Eric and Heather have been downloading the receiver array in the Strait of Belle Isle and the salmon have begun to pass through.  They have also been fishing the fyke net, though have not caught any post-smolts yet. Lots of capelin and a lone adult salmon have been caught and released on their way however. They are now out on the big boats with the live-trawl in the strait itself, and we eagerly wait to hear details of what they find. </div><div class="plain"><br></div><div class="plain">They did have a few visitors in the form of killer whales over the past few days. While the Orcas frequent inshore waters on the Pacific Coast, out here they tend to stay offshore, except for some areas of Newfoundland and Labrador and the Strait of Belle Isle. <br></div><div class="plain"><br></div><div class="plain"><img width="750" daid="17832813" src='//0104.nccdn.net/1_5/180/11c/250/Orca-SOBI-July-2018.jpg' height="562" border="0"><br></div><div class="plain"><br></div><div class="plain">Back in New Brunswick, ASF staff were at the Department of Fisheries and Ocean's Mactaquac Biodiversity Facility taking some samples from migrating salmon for the fish health project. These fish were caught by DFO as they reach the Mactaquac Dam, are sorted and measured and then trucked beyond the dam to continue on their way. We're taking a few small tissue samples to compare disease agent presence between stocks that have to pass through aquaculture areas and those that don't. The sampled fish are anesthetized before hand and are released with the rest of the fish afterwards. The day went well and we'll be back late this week to finish the sampling. Unfortunately, the numbers returning to the Saint John River so far this year are not too high.</div><div class="plain"><br></div><div class="plain"><img width="750" daid="17832814" src='//0104.nccdn.net/1_5/180/11c/250/20180718_112147.jpg' height="421" border="0"><br></div><div class="plain"><br></div><div class="plain"><i>Graham Chafe, ASF Research.</i><br></div><p class="plain"></p> Graham 2018-07-18T17:12:30-07:00 Capelin, Killers and Salmon What the Fyke? http://asf.ca/pc_url_38563470 It's the beginning of July and ASF biologist Eric Brunsdon and Dalhousie University summer student Heather Perry are searching for post smolt at the Strait of Belle Isle. Post smolt are juvenile salmon on their first ocean migration and ASF's research has shown that almost all of them coming from Gulf of St. Lawrence rivers pass through the Strait of Belle Isle. <div class="plain"><br></div><div class="plain">Capturing post smolt will give valuable information about their size and condition, and by eventually tagging these growing young salmon, ASF will be able to expand the reach of our tracking program further into the Labrador Sea. <br><br>Eric and Heather began the week by setting up a fyke net off L'Anse-Amour on the Labrador side of the Strait of Belle Isle. A fyke net is a fixed trap with hoops and long wings that gently captures fish moving along the coast. It's shaped so fish that have entered the fyke net are discouraged from leaving. The net will be checked at least once a day for post-smolts and to release any by-catch. The fish are not harmed by becoming trapped in the net. It took a long day to site and set it up, but it is now fishing well.<br><img width="700" daid="17823589" src='//0104.nccdn.net/1_5/052/0b5/01e/DSCN5461.JPG' height="525" border="0"><br><br>They are also checking on and downloading the receiver array recently deployed across the strait. The fyke net and data downloads will serve to alert them that post-smolts are passing through the strait. They will then begin live-trawling using local fishers to capture the fish as they pass the strait. Meanwhile, back at the office, ASF Biologist Jason Daniels is using the early data from the receivers in the Miramichi River and sea-surface temperature data to predict when the post-smolts will arrive where Eric and Heather are. So far, it looks like they are ahead of the game and are well-prepared for the arrival of post-smolts from southern Gulf of St. Lawrence rivers. We'll keep in contact with the crew in Labrador for any updates, no salmon so far, but they have seen some whales and a few icebergs!<br><i>Graham Chafe, ASF Research.</i><br><p class="plain"></p></div> Graham 2018-07-04T09:32:58-07:00 What the Fyke? SoBI It. http://asf.ca/pc_url_38555138 <p class="plain"></p><div class="plain">As the end of June nears, salmon smolts from Gulf of St. Lawrence rivers are getting closer to the Strait of Belle Isle (SoBI). For many years, ASF has deployed lines of receivers across the strait to detect tagged smolt as they pass. Last week, ASF's Vice President of Research Jon Carr and Newfoundland and Labrador program director Don Ivany laid out the receivers with the help of lobster fishermen Loomis Way. There are two lines to increase the chances of detection and each line consists of receivers placed about 600m apart. The southern line also has sentinel tags, the same as those placed inside out migrating smolt, fixed in place between some receivers. These sentinel tags allow us to gauge the detection probability, or effectiveness of the line. While tags can be heard by receivers several hundred meters away in optimal conditions, conditions in the ocean are usually less than ideal. This allows us to calculate how many fish we may have missed and adjust our estimates accordingly.</div><div class="plain"><br></div><div class="plain"><img width="700" daid="17820449" src='//0104.nccdn.net/1_5/063/2c8/080/A7B0C7E5-4A86-4CC9-B11D-88A3FD434D1A.jpeg' height="525" border="0"><br></div><div class="plain"><br></div><div class="plain">Once Jon Carr finished deploying gear, he went over to the Labrador side to meet up with ASF Biologist Eric Brunsdon and Dalhousie student Heather Perry to help with preparations for their activities. They'll be conducting some surveys of the passing smolts using live trawl and fyke nets. Their attempts will help guide our activities over the next few years and hopefully with emerging technologies to extend our tracking capabilities into the North Atlantic. We look forward to more updates and photos from our staff in the field in the coming weeks.</div><div class="plain"><br></div><div class="plain">Happy Canada Day.</div><div class="plain"><br></div><div class="plain"><i>Graham Chafe, ASF Research.</i><br></div><p class="plain"></p> Graham 2018-06-27T07:36:48-07:00 SoBI It.

Mike and Eric are waiting on the weather to visit Miramichi receiver installations to download some and retrieve others. The smolts have passed by now and are on their way to the Strait of Belle Isle. At the strait, Don Ivany and a local fisher are gearing up to get the array into the water there to be ready for the smolts' passing.

We were collecting receivers we had placed there a month ago to detect passing smolts. While some receivers further downstream are left in, these are removed much earlier. Since the smolts have passed and the adults are detected eslewhere, we remove these receivers to make sure we get the data and so that they are out of the way of any anglers in those sections.</div><div class="plain"><br></div><div class="plain">Eric and Heather, our other Dalhousie University summer student, will be headed to Newfoundland on the weekend to begin our expanded activites there. They'll be looking to capture post-smolts to collect information from them before releasing them on their way. They'll also be sampling for a fish health program, looking at the presence of certain pathogens from Gulf of St. Lawrence salmon.

We've also seen a few adult alewife, the ones that ascended early and are on their way out already. To date, we've also counted three small chain pickerel, an invasive species in the system that have taken hold.</div><div class="plain"><br></div><div class="plain"><img width="400" daid="17803309" src='//0104.nccdn.net/1_5/1b6/13d/09a/20180529_093406.jpg' height="711" border="0"><br></div><div class="plain"><br></div><div class="plain">The upstream passage on the same system is busy with alewife on their way to spawn in the river. While we don't count them, nor are there facilities to do so, the run last year seemed larger than usual. It definitely was a bigger year for the neighbouring St. Croix River and early indications for 2018 seem to suggest the same. The photo above shows a few alewife climbing from pool to pool on the fish ladder. The pools are full of them and they move mostly in sunny weather. There was at least one larger predator after them just below the ladder the other day. Although we didn't see it directly, it did create a very large wake as it scattered the alewife all over the place.

Eric and Michael were up on the Restigouche tagging kelts. Thanks to David Leblanc, the Restigouche River Watershed Management Council and all the volunteer anglers for making it a success. They didn't manage to tag all the fish we had planned, but considering the late season and tricky conditions, it went very well. Meanwhile, Jason and I were on the Northwest Miramichi after smolts. The run wasn't too strong while we were there so Eric and Michael stopped by on the way home and finished up for us so we could head to the Southwest Miramichi for another batch of tagging. The Miramichi Salmon Association and Kelsey McGee get a big thanks for setting up and operating the smolt wheel and fishing it every day for us.  Thanks also goes to Debbie Norton and the Upper Oxbow camp for supporting us while we were there.

Eric and Ellen went up to the Grand Cascapedia River a few days ago to acoustically tag kelts. This is the first year we've tagged kelts in that river and hope for some good results. This project is being undertaken with the Cascapedia River Society and with big help from anglers from the Gesgapegiag First Nation. The folks on the river clearly knew when and where the fish would be, they caught and tagged 17 on the first day and the last 6 on the second.

Depending on ice conditions in the bay and when we can get the Chaleur line out, they will be recorded there as well. Fish destined to be alternate spawners are likely to cross the Strait of Belle Isle in early July and our receiver line there will be in place by then.It will be interesting to see how their timing compares to the nearby Restigouche River where we've been tagging black salmon for several years.</p><p class="plain"><br></p><p class="plain"><img width="400" daid="17778385" src='//0104.nccdn.net/1_5/02a/271/2af/5.5.jpg' border="0"><br>Speaking of the Restigouche, we'll be tagging kelts there in about a week and a half, sometime between the 5th and 8th of May, and several days earlier on the Northwest Miramichi.

We'll be investigating our ability to capture post-smolt as they move through the strait on their way to the North Atlantic. Any salmon captured will be have some measurements taken and samples of a few scales and a tiny bit of tissue. This will yield more knowledge about what conditions and changes these fish faced as they moved through the Gulf of St. Lawrence. Additionally, knowing the size and weights of the fish allow us to plan for future technologies for potential tagging opportunities when they present themselves. Currently we can't track fish much past that point, but in the future it may well be an option and we'd like to be ready.<br><br><img width="750" daid="17774777" src='//0104.nccdn.net/1_5/22a/0f0/2af/Snapshot_0.png' height="421" size="-1" border="0"><br><br>The trawl itself has a live box, adapted from some friendly researchers south of the border, that will move fish into a chamber out of the push of the water and be well-protected.

From September to the end of January, a student lives in Saint Andrews and works with the ASF Research Department. This year, Clement Taron was our guest for five months. He was interested in fish in general and salmon specifically and so followed in the footsteps of Caroline, Marine and Alaia before him. He integrated well into our department and jumped right in to working with some of our data. He also enjoyed his time in Canada and traveled some within New Brunswick and Quebec. For some reason, all the interns from Agrocampus Ouest spend Christmas in New York City and Clement was no exception. Though the weather caused him a five day delay returning from New York, he was back at it in the beginning of January.<br><br><img width="700" daid="17722409" src='//0104.nccdn.net/1_5/2fd/209/170/Clement-Taron-with-Research-Department-2-Feb-2018.jpg' height="525" size="-1" border="0"><br><br>Clement was interested in the relationship between temperatures in the Gulf of St. Lawrence and post-smolt migration.

Improving Passage http://asf.ca/pc_url_38325889 <p class="plain">With dams all over the province, NB Power is an important player for fish passage. While we all want and need our electricity, the sourcing of that power has large effects on the environment. Hydro power, often touted as renewable, has a particularly obvious effect on migratory fish populations. Its hard enough swimming upstream, but when a dam is in the way it changes things completely. Fish ladders, trap and truck and fish lifts all exist in New Brunswick and have varying degrees of success.<br><br><img width="400" daid="17714016" src='//0104.nccdn.net/1_5/163/114/032/20180124_153545.jpg' height="225" border="0"><br><br>In an upcoming refit of the Milltown dam in St. Stephen, NB Power is planning to use newer technology for both upstream and downstream passage. The dam, the oldest continually running hydro plant in the country, will be outfitted with DIVE turbines from Germany that are apparently more fish friendly. However the real intent is for fish to use a new 'Hydroconnect' system. It is a double rotating hydropower screw in a large tube. It is kind of like two Archimedes screws, one inside the other and going in opposite directions to lift fish up or pass fish down. <br><br>While both the turbines and fish passage systems have been used in Europe, Milltown will be the first installations in North America. Good for NB Power for exploring the potential of new and emergent technology. It will take some tweaking and working with flows and timing  to figure it out, but if all goes well it will be an example for other dams in our area and beyond. If it doesn't work too well, the existing fish passage facilities will remain.<br><br>ASF staff and many others were at a stakeholder meeting yesterday, which was followed by one for the public in the evening. Several concerns were raised (will fish be able to find the Hydroconnect entrance amidst all the water in the tailrace for example) over the afternoon. I encourage anyone interested to attend other consultations and offer their input.

Ellen Mansfield began this week as Office Manager with our department. She comes to us from Southwest NB Service Commission where she was the Safety/Environmental Affairs staff for several years.

They have moved from the holding pools to spawning grounds and are busy working towards future generations. Also on the river are salmon biologists, conservationists and anglers who are looking to see the results of that activity. When salmon spawn, the female dig depressions in the gravel, called a redds, in which to deposit her eggs. The male moves alongside the female over the redd and expresses his milt while she deposits her eggs. Thus they are fertilized as they sink into the depression. She then covers over the redd so that the eggs are protected from many predators while they develop over the winter.<br><br><img width="550" alt="" daid="17658789" src='//0104.nccdn.net/1_5/0fb/27e/069/Z' title="" height="387"><br><br>While the eggs are buried and hidden, the recently turned gravel is a giveaway to those who know what to look for (Lee is pointing to a redd in the photo). Many watershed associations, angling groups and biologists head out on the rivers around this time of year to count redds. They won't achieve exact number of eggs laid of course, typically only certain areas are surveyed, but it does give an idea of any given year's returns or useage of a reach compared to the past. It also provides eyes and ears on the rivers to look out for new obstructions or other impediments to migrating fish. The ASF's Geoff Giffin and Graham Chafe have recently been out with Lee Robinson of the Hammond River Angling Association counting redds on that river. I was there was just after a rise and fall in the water and redds were harder to spot as they had been re-silted and so didn't stand out as much. Geoff and the Hammond group covered a few kilometers of river and counted many redds, a good sign and always reassuring that spawning is continuing. <br><br>If you're interested, look to local watershed or angling groups to take part in a redd count, it is a great way to spend a late fall day wandering a river or stream and contributes to knowledge about our favourite fish species.<br><br><i>Graham Chafe, ASF Research.</i><br></p> Graham 2017-11-15T12:17:23-08:00 Seeing Redd Grates and Ladders http://asf.ca/pc_url_38164506 <p class="plain">At this point in the year, we don't have a lot of field work left, desk season is approaching. There are a few things left, temperature loggers across Charlotte County that need to be picked up and the Magaguadavic fishway needs checking a few times a week.<br><img width="400" alt="" daid="17644694" src='//0104.nccdn.net/1_5/273/06d/3e5/Z' title="" height="224"><br>The high winds and heavy rains of the past several days took the leaves off the trees, removing a lot of the colour from the landscape in the course of hours. When we checked the fishway over the weekend, it seemed like most of the leaves had ended up in there, clogging grates and threatening to hold back the flow. It also seemed that the high water and faster flows may have washed a few fish below the dam. The landlocked salmon here made its way back up the ladder, was quickly measured and photographed before continuing its way back to- the river.<br><br>We don't expect to see many more fish, but we'll keep checking until mid-December. At that point we'll bypass the research trap so fish can make their way freely into the river.<br><br><i>Graham Chafe, ASF Research.,</i><br><br><br><br><br><br><br><br><br><br></p> Graham 2017-11-01T05:41:04-07:00 Grates and Ladders Great Scott http://asf.ca/pc_url_38125699 <p class="plain">The ASF Research Department has been tagging salmon kelts with pop-up satellite tags since 2012. These tags are archival, meaning that they record information every so often and store it on-board. Some archival tags need to <img width="250" align="left" daid="17626984" src='//0104.nccdn.net/1_5/1cd/008/1aa/callum.jpg' style="margin: 15px 15px 15px 0px;float: left" size="250" border="0">be retrieved in order to access that data, but in the case of pop-up archival satellite tags (PSATs), they can transmit the data. They 'pop-off' the fish at a pre-determined time, or when sensors suggest the fish has died, and float to the surface. From there, virtually anywhere on the planet, they can transmit to the ARGOS network of satelites. That network is used by scientists for all kinds of fascinating research.<br><br>In the spring of 2015, we tagged a kelt in the Northwest Miramichi River with a PSAT. Unfortunately we never received any transmissions from the tag. In the summer of 2016, we found out why. The tag had washed ashore on the Outer Hebrides, Scotland, where it happened to be found by young Calum McLeod. He noticed two things about the tag, that the antennae was broken and information on the tag asking finders to contact the ASF. He did just that and sent it back, along with some fishing stories and hand-drawn art of some of his catches.<br><br><img width="750" daid="17626960" src='//0104.nccdn.net/1_5/324/198/2a9/IMG_20160807_192317344.jpg' height="421" size="-1" border="0"><br><br>The data took some time to extract and analyse the data (more data is available for recovered tags than can be transmitted), but that process is complete now. The kelt in question was tagged in early May, went to see soon after and meandered towards Gaspe and Anticosti Island. Throughout June it moved along the north shore of the Gulf of St. Lawrence, out the Strait of Belle Isle and then offshore. By July it was way off West Greenland. Unfortunately at this point the data shows that it was predated. The temperature data after predation show much warmer temperatures than the surrounding water, warm enough to be consistent with a marine mammal.  The unfortunate truth for wild Atlantic salmon is that they are prey species for some other animals, however it is nice to know that this particular fish did reproduce at least once before meeting its fate.<br><img width="700" daid="17626953" src='//0104.nccdn.net/1_5/36f/2a9/2a0/148263-2015-Track.PNG' height="633" size="-1" border="0"><br>Thanks to Calum for keeping his eyes open that day on the beach and reaching out to us. The data from this tag will add to a growing knowledge base of the marine migration routes and diving behaviour of Atlantic salmon kelts as well as predation events.<br><br><i>Graham Chafe, ASF Research.</i><br></p> Graham 2017-10-11T10:11:24-07:00 Great Scott
