An elegant new study shows that multiciliated cells in the noses of aquatic vertebrates generate flow fields that help odor detection and processing.

Many recreational anglers practice catch-and-release angling, where fish are returned to the water with the presumption that they will survive. However, not all fish survive, and those that do often experience sublethal consequences including injury and stress. There is compelling scientific evidence that angler behavior and gear choice can affect the success of catch-and-release as a managemen...

The effect of catch-and-release fishing on the survival of peacock bass (Cichla spp.) was evaluated by comparing two types of artificial bait (jig and shallow-diver plugs) and two types of post-catch confinement. Two experiments were conducted during the periods January-February and October-November 2012 in the Unini River, a right-bank tributary of the Negro River. In total, 191 peacock bass w...

We recently identified saffron cod Eleginus gracilis as a dominant fish species in nearshore habitats (<5 m deep, <20 m offshore) of western Prince William Sound (PWS), Alaska, USA. Saffron cod have not been previously reported in PWS, and their capture suggests that fish community structure has changed in nearshore habitats. Nearly 16 000 saffron cod were captured in 49 of 95 beach seine hauls...

The dactylopterid fishes are non-commercial fishes and occasionally caught as a by-catch during commercial trawling. Two specimens of Dactyloptena peterseni were collected during the survey of commercial trawl catch at Karachi fish harbor. This is the first report on the occurrence of Dactyloptena peterseni in the Pakistani waters. The present study gives the detail description of morphometric ...

This paper summarizes a natural resource damage assessment for the State of Montana. Mining wastes have caused significant reductions in trout stocks in a 145-mile stretch of Montana's Silver Bow Creek and Clark Fork River. To estimate economic damages from decreases in catch rates, we develop and estimate an individual-based utility-theoretic model of where and how often an angler will fish as...
