Nonnative species that form novel habitats strongly affect ecosystem processes. The effects of these ecosystem engineers can be both positive and negative but the mechanisms behind their effects are not well described. In this study Jeffrey T. Wright...
AQUAPLAN 2014-2019 - Australia's National Strategic Plan for Aquatic Animal Health
AQUAPLAN 2014–2019 is Australia’s third national strategic plan for aquatic animal health. It outlines the priorities to strengthen Australia’s arrangements for managing aquatic animal health, and to support sustainability, productivity, and market...
When Is Spillover from Marine Reserves Likely to Benefit Fisheries?
The net movement of individuals from marine reserves to the remaining fishing grounds is known as spillover and is frequently used to promote reserves to fishers on the grounds that it will benefit fisheries. Here Colin D. Buxton et al, University of...
Stickleback Fish Dads Influence Offspring Behaviour and Gene Expression
Researchers report that some stickleback fish fathers can have long-term effects on the behavior of their offspring. The most attentive fish dads cause their offspring to behave in a way that makes them less susceptible to predators. These behavioral...
Eyeless Mexican Cavefish Eliminate Circadian Rhythm to Save Energy
Eyeless Mexican cavefish show no metabolic circadian rhythm in either light and dark or constant dark conditions, according to a study published September 24, 2014 in the open-access journal PLOS ONE by Damian Moran from Lund University, Sweden, and colleagues....
The Secret Life of the Sea Trout
Jan G. Davidsen and his graduate students are spies. They use listening stations and special tags they attach to their subjects to track their movements. They follow their subjects winter and summer, day and night.They are in pursuit of secrets and are...
Persistence of Tetracapsuloides Bryosalmonae (Myxozoa) in Chronically Infected Brown Trout
Proliferative kidney disease is a widespread disease of farmed and wild salmonid populations in Europe and North America, caused by the myxozoan parasite Tetracapsuloides bryosalmonae. Ahmed Abd-Elfattah et al, University of Veterinary Medicine, Austria,...
Fisheries and Aquaculture of the United States 2013
This publication is the annual National Marine Fisheries Service (NMFS) yearbook of fishery statistics for the United States. The report provides data on U.S. recreational catch and commercial fisheries landings and value. ...
Effects of Temperature, Digestion on the Swimming Performance of Juvenile Chinese Bream
To test whether digestion affected swimming performance in an active forager and whether the possible effects varied with temperature, Jing Peng et al, Chongqing Normal University, investigated the critical swimming speed (Ucrit) and the resting and active...
The Noisy World of Mud Crabs
Fish are not silent crea­tures. Just like the ter­res­trial world, there’s a ver­i­table sym­phony of sound echoing under the sea. ...
Farmed Milkfish as Bait for the Tuna Pole-and-line Fishing Industry in Eastern Indonesia: A Feasibility Study
Pole-and-line fishing is considered to be a sustainable method for catching tuna. However, the reliance on baitfish, which are commonly very variable in their availability, has the potential to introduce unsustainable elements to the fishery, write Arun...
The Role of Fish in the First 1,000 Days in Zambia
Fish is especially rich in essential omega-3 long-chain polyunsaturated fatty acids and micronutrients, including bioavailable calcium, iron and zinc. Fish features prominently in the diet of most, especially poor, Zambians. Despite this, its significance...
Effects of Salmon Lice Infection on the Behaviour of Sea Trout in the Marine Phase
Salmon lice Lepeophtheirus salmonis Krøyer may affect survival and growth of anadromous salmonids through physiological stress and/or behavioural changes. Using acoustic telemetry tracking, Karl Øystein Gjelland et al, Norwegian Institute for Nature...
Improving the Management of Baitfisheries Associated with Pole-and-Line Tuna Fishing in Indonesia
The International Pole & Line Foundation (IPNLF) and its Indonesian stakeholders are working on improving the management of Indonesian pole-and-line fisheries and the associated bait fisheries. ...
African Cichlid Fish Study Reveals Diverse Molecular Mechanisms Underlying Evolution
In an effort to understand the molecular basis of adaptation in vertebrates, BBSRC-funded researchers have sequenced the genomes and transcriptomes of five species of the African cichlid fish and uncovered a variety of features that enable the fish to...
