The first otlicial occurrence of the exotic species Clarias gariepinus (Burchell , 1822) in the Rio Paraopeba (Sao Francisco river basin), the Rio Grande (Parana river basin), and the Rio Doce (Doce river basin), is reported, with comments on the possible ecological consequences and on the conservation of freshwater fish biodiversity due to non-native species introductions.

A range expansion of the Taiwan sardinella Sardinella hualiensis to the Philippines is reported. The data suggested that the southern translocation of S. hualiensis occurred across oceanographic features that are typically barriers to small, pelagic fish dispersal. With this addition, the Philippines is among the most diverse countries for Sardinella biodiversity in the world, second only to In...

Fish is a distinctive aquatic food item that benefits both physical and mental health. serves as useful diet contributes to human growth development well the prevention treatment of many ailments are linked modern civilization. High quality protein, fat, carbohydrate, minerals, vitamins found in fish all beneficial nutrition. The most important requirement for sustainable eradicate hunger malnu...

A recent threat to European fish diversity was attributed to the association between an intracellular parasite, Sphaerothecum destruens, and a healthy freshwater fish carrier, the invasive Pseudorasbora parva originating from China. The pathogen was found to be responsible for the decline and local extinction of the European endangered cyprinid Leucaspius delineatus and high mortalities in stoc...

The long-term species diversity patterns in marine fish communities are garnering increasing attention from ecologists and conservation biologists. However, current databases on quantitative abundance information lack consistent long-term time series, which are particularly important in exploring the possible underlying mechanism of community changes and evaluating the effectiveness of biodiver...

The marine biodiversity of Gabon, West Africa has not been well studied and is largely unknown. Our examination of marine communities associated with oil platforms in Gabon is the first scientific investigation of these structures and highlights the unique ecosystems associated with them. A number of species previously unknown to Gabonese waters were recorded during our surveys on these platfor...

Most of Singapore’s coastline has been modified by coastal development with variable influences on marine biodiversity. Marinas are typically designed as a semienclosed environment with a complex mix of structures that provide ecological niches throughout the water body. Water flow is inevitably reduced with a possible decline of water quality. This investigation was conducted to determine how ...

Coral reefs, one of the most biologically diverse and important ecosystems on Earth, are experiencing unprecedented and increasing ecological decline, yet the fish faunas of such reefs and other tropical shoreline habitats remain poorly known in many areas. Rotenone, a natural substance traditionally used by subsistence fishers, is a uniquely efficient tool for sampling reef and other shore fis...

Most marine animals, particularly marine mammals and fish, are very sensitive to sound. Noise can travel long distances underwater, blanketing large areas, and potentially preventing marine animals from hearing their prey or predators, finding their way, or connecting with mates, group members, or their young. Decreased species diversity in whales and dolphins was related to an increase in seis...
