Quick answers to common questions
Understanding the dynamics of disease transmission and outcomes for impacted individuals is challenging in natural systems, so fish health experts often try to replicate natural conditions in the laboratory. However static baths, often used for dosing studies, are not reminiscent of flowing water riverine environments.
Today’s paper is an assessment of angler attitudes regarding Striped Bass populations, angling tactics, and regulations. It’s the culmination of a substantial online survey of anglers (N=1,651), and provides a wide variety of angler perspectives.
The project looked at zooplankton harvest from fishless aquaculture ponds, what impacts that had on the phytoplankton and zooplankton communities in those ponds, and how that compared to control systems. It also included the rationale for why one might want to undertake such an activity…
Today’s paper caught my attention, as it looks at the relationship between fish and water quality. That’s long been an area of interest for me. The title addresses changing water clarity, but the causal factor is invasive mussels in the Great Lakes.
“Failing to respond to efforts restricting climate change research, scientific knowledge sharing, and management strategies to alleviate human-caused climate change will continue to have ever-more dire consequences for human societies and our planet.”
Today’s paper is from NAJFM, and it caught my attention because it reminded me about the great Black Bass 2025 meeting that was held in association with the AFS Annual Meeting. The paper also relied on angler-derived data, which I think is a substantial area of growth for fisheries management.
Today is a special Fishy Friday, because you get both a paper and a video! Today’s paper is from TAFS, and it documents fish passage in the Eel River, Indiana, following the installation of a Kynard fishway at a lowhead dam. The accompanying video addresses this type of innovative fishway, and its success in passing small bodied fish.
Ecosystem‐level reference points: Moving toward ecosystem‐based fisheries management, by Wendy E. Morrison, Stephanie A. Oakes, Melissa A. Karp, Max H. Appelman, and Jason S. Link
Real‐time triplex loop‐mediated isothermal amplification (LAMP) using a turbidimeter for detection of shrimp infectious hypodermal and hematopoietic necrosis virus (IHHNV), by Narong Arunrut, Sarocha Jitrakorn, Benyatip Tondee, Vanvimon Saksmerprome, and Wansika Kiatpathomchai.
Multiscale analysis predicts native species presence based on habitat and nonnative species abundance, by Crosby Hedden, Skyler Hedden, Keith Gido, Alexander C. Cameron, David Propst, and William Stewart.
Today’s paper caught my attention for a couple of reasons. One, I read a separate blue crab/Blue Catfish article a couple weeks ago. Two, one of my staff was at a family gathering recently, and indicated they were asked if the Chesapeake Bay blue crab fishery was going to be shut down – they apparently were supposed to know the answer because they are involved in fisheries!
Today’s paper caught my eye because I have read a few items regarding the introduction of salmon to the Great Lakes. I was aware of the variety of issues that caused the decline of the Lake Trout, including the thiamine issue due to the Alewife diet. I was unaware that similar issues were prevalent in other salmonids, or of the high offspring mortality due to thiamine deficiency in Chinook Salmon eggs.
