Genetic study of populations of two species of genus <i>Trachurus: T. lathami and T. symmetricus</i>
Journal of Renewable Natural ResourcesWe conducted a population genetics study of two species of the genus Trachurus: T. symmetricus and T. lathami by analyzing the genetic structure of each species. This was performed by enzymes and mitochondrial DNA electrophoresis in starch, polyacrylamide and agarose respectively to establish the degree of relationship between species. The results show

Patterns of distribution and abundance of larval phosichthyidae (actinopterygii, stomiiformes) in southeastern Brazilian waters [PDF]
, 2011 Horizontal and vertical distribution patterns and abundance of larval phosichthyids were investigated from oblique and depth-stratified towns off Southeastern brazilian waters, from São Tomé cape (41ºW.; 22ºS.) to São Sebastião island (45ºW.; 24ºS.). The

The Northern Anchovy reduction fishery for the 1978-79 through 1981-82 seasons [PDF]
, 1985 Nearly 49,000 metric tons (MT) of anchovies were taken during the 1978-79 season, followed by 32,390 MT in 1979-80, 60,678 MT in 1980-81 and 45,150 MT in 1981-82. A total of 14,076 fish was sampled during the four seasons for age, length and sex.

Initiation and spread of escape waves within animal groups [PDF]
, 2015 The exceptional reactivity of animal collectives to predatory attacks is thought to be due to rapid, but local, transfer of information between group members. These groups turn together in unison and produce escape waves.
