V. anguillarum is the most well-studied and widespread fish-pathogenic Vibrio species, and is responsible for the majority of fish loss in aquaculture worldwide (Austin and Austin 2007).
Excess N delivered to estuaries and oceans produces harmful algal blooms, which can lead to hypoxia and even dead zones resulting in widespread fish kills [2], [3].
In view of the widespread fish-trading industry, this hybrid clone may eventually emerge through exports of Israeli tilapia stocks, in remote geographic locations.
Over the recent 20 years, the South Florida ecosystem has experienced excessive mercury bioaccumulation, resulting in widespread fish consumption advisories (FDOH 2008).
Rainbow trout (Oncorhynchus mykiss) is one of the most widespread fish invaders in the world, having been introduced to 90 countries worldwide (Casal 2006) and being listed as one of the '100 World's Worst Invasive Alien Species' (ISSG 2008).
In this study, we present a comparative study aimed at evaluating the effects of anthropogenic river fragmentation on the genetic integrity of four widespread fish species (the European chub, Leuciscus cephalus; the rostrum dace, Leuciscus leuciscus; the gudgeon, Gobio gobio and the European minnow, Phoxinus phoxinus).
In this study, we identify DUs in an even more widespread fish species that occurs across a variable landscape, which displays remarkable variation within and between populations in ecology, life-history evolution and biogeographic history, and which has high taxonomic and phenotypic complexity.
Cattle breeding is widespread, and fishing is practiced off the coast.
Over the past few decades, the Danube has witnessed drastic changes in land use, over-exploitation of natural resources, hydraulic re-engineering through damming, embankment and re-channeling, and widespread illegal fishing.
