Recent Region-wide Declines in Caribbean Reef Fish Abundance [PDF]

Current Biology, 2009
Profound ecological changes are occurring on coral reefs throughout the tropics, with marked coral cover losses and concomitant algal increases, particularly in the Caribbean region. Historical declines in the abundance of large Caribbean reef fishes likely reflect centuries of overexploitation.

Spatial and temporal variation of fish assemblage structure in a neotropical Mexican river

Revista Mexicana de Biodiversidad, 2021
The introduction of non-native fish into the Teuchitlán River, in west-central Mexico, was suggested as a key factor behind the change in the fish assemblage, and even in the extinction of endemic species. The characterization of the fish assemblage and

Time-based method for determining fish abundance in fishing rivers

Vestnik of Astrakhan State Technical University. Series: Fishing industry, 2020
The article touches upon the problem of the rational use of fish stocks in fishing water bodies, which implies using modern accounting methods for fish abundance and fish stocks. To this end, instrumental surveys are carried out. In the fishing rivers of Kazakhstan (the Zhayik and Kigash Rivers) there was previously used the biostatistical method of ...
