A global baseline for spawning aggregations of reef fishes.
Species that periodically and predictably congregate on land or in the sea can be extremely vulnerable to overexploitation. Many coral reef fishes form spawning aggregations that are increasingly the target of fishing. Although serious declines are well known for a few species, the extent of this behavior among fishes and the impacts of aggregation fishing are not appreciated widely. To profile...
متن کاملA video method for quantifying size distribution, density, and three-dimensional spatial structure of reef fish spawning aggregations
There has been growing interest in measuring individual sizes of fishes at liberty and capturing three dimensional (3D) attributes of fish schools or aggregations in situ (Parrish and Hamner, 1997), particularly on exploited populations that have not been assessed using fisheries independent methods. There is a relatively long history of using ship-mounted sonar for quantifying attributes of fi...
متن کاملBiotransformation of inorganic arsenic in a marine herbivorous fish Siganus fuscescens after dietborne exposure.
Arsenic (As) is well known to be biodiminished along marine food chains. The marine herbivorous fish at a lower trophic level are expected to accumulate more As. However, little is known about how marine herbivorous fish biotransform the potential high As bioaccumulation. Therefore, the present study quantified the biotransformation of two inorganic As species (As(III) and As(V)) in a marine he...

15 صفحه اولSpatio-temporal dynamics of a fish spawning aggregation and its fishery in the Gulf of California
We engaged in cooperative research with fishers and stakeholders to characterize the fine-scale, spatio-temporal characteristics of spawning behavior in an aggregating marine fish (Cynoscion othonopterus: Sciaenidae) and coincident activities of its commercial fishery in the Upper Gulf of California. Approximately 1.5-1.8 million fish are harvested annually from spawning aggregations of C. otho...
