Assessing the threat of non-native salmonids to Lahontan cutthroat trout recovery in a subalpine watershed [PDF]

, 2018
Introductions of non-native fishes complicate native fish recovery and introductions of non-native salmonids have been implicated in the decline of inland cutthroat trout subspecies.

Future Trends in Angler Behavior Based on a Delphi Study in the Nordic Countries

Fisheries Management and Ecology, EarlyView.
ABSTRACT Recreational fisheries are dynamic social‐ecological systems. Identification of anticipated future trends supports the design of policies and management to deliver outcomes for fisheries resources, users, and communities. To this end, we applied a forecasting method (i.e., Delphi survey) to recreational fisheries in five Nordic countries.

Embracing nanotechnology for selenium application in aquafeeds

Reviews in Aquaculture, Volume 15, Issue 1, Page 112-129, January 2023., 2023
Abstract Selenium (Se) is an important micronutrient that has been used in aquafeeds for the normal growth, welfare and health of aquatic animals. Through nanotechnology, Se can be converted into nanoparticles that are more bioavailable, utilized and absorbed by aquatic animals.

Quantitative Estimates of Nutrient Inputs From Angling Baits in Lakes Supporting Different Recreational Fisheries

Fisheries Management and Ecology, EarlyView.
ABSTRACT Recreational anglers use ground baiting to attract fish and increase catch inputs organic matter that can have important effects on water quality by increasing eutrophication. However, nutrient inputs from angling bait by recreational fisheries have not yet been estimated.

Environmental risk assessment of non‐native salmonid escapes from net pens in the Chilean Patagonia

Reviews in Aquaculture, Volume 15, Issue 1, Page 198-219, January 2023., 2023
Abstract Here, we review extensive information to estimate environmental risks from escaped non‐native salmonids based on the assessments of hazard, sensitivity and exposure of discrete water bodies in Chile. In 2020, the country harvested about 1 million tons salmonids from net pens located along 1500 km of highly biodiverse coastline.

Effects of Temperature, Air Exposure Time, and Bleeding on Post‐Release Movement of Angled Channel Catfish

Fisheries Management and Ecology, EarlyView.
ABSTRACT Catch‐and‐release angling is an effective conservation tool only when released fish survive. Measuring the physiological response of sportfish to capture has recently been enhanced by the use of accelerometers to measure post‐release movement.

Reproductive sterility in aquaculture: A review of induction methods and an emerging approach with application to Pacific Northwest finfish species

Reviews in Aquaculture, Volume 15, Issue 1, Page 220-241, January 2023., 2023
Abstract Aquaculture is the fastest‐growing food‐production sector and is striving to become a long‐term sustainable approach to meet the rising global demand for seafood. During the expansion and advancement of aquaculture, minimizing ecological impacts should occur concomitantly with maximizing production. Farmed fish, often genetically distinct from

Creatine: A valuable supplement in aquafeeds?

Reviews in Aquaculture, Volume 15, Issue 1, Page 292-304, January 2023., 2023
Abstract Creatine is an amino acid derivate commonly found in vertebrate muscle tissue. Creatine facilitates the recycling of adenosine triphosphate and thus contributes to the energy supply of the muscles as well as the brain. Creatine is used as a supplement for several reasons and its effects in humans, particularly in sports medicine, have been ...
