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...
When Is Spillover from Marine Reserves Likely to Benefit Fisheries?

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...
European Seabass Perform Better in Cages With a Big Volume
Although the effects of fish density on the performance of fish have been widely studied, there has been little work done into the effect of cage size on seabass performance, said Athanasios Samaras speaking at Aquaculture Europe 2014, writes Lucy Towers,...
