The materials on the retrospective and current catch of marine fish species in Far Eastern region are presented. In seas, from 3.0 to 3.4 million tons LMR captured, constituting more than 2/3 total Russian catch. 2019, commercial fishes, for which TAC is set, amounted 2.3 tons. structure dominated by walleye Pollock (75%), herring (11%), cod (6%), flounder (3 %), saffron (2.5%). non-quota 354.6...

Feeding habits of Caspian marine shad Alosa braschnikowii (Borodin, 1904), inhabiting in the western part of Caspian Sea such as prey spectrum and seasonal dynamics have been studied. As in other parts of Caspian Sea, throughout the year, the main hunt of Caspian marine shad constituted kilkas, gobies and shrimps while other groups of zoobenthos were represented in a lesser extent. Importance o...

The steps by which neutral, random and/or negative biological interactions evolve into mutualistic ones remain poorly understood. Here, we study Elacatinus gobies and the 'client' fishes they clean. Colourful stripes are common to mutualist cleaners and noncleaning sister species. Blue stripes are unique to cleaners and are more conspicuous to predators than are basal yellow or green stripes. I...

In this article, the complete mitogenome of the amphidromous, red-tailed goby, Sicyopterus lagocephalus has been amplified and sequenced by long polymerase chain reaction. This mitochondrial genome consists of 16,500 bp, with 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes, and a non-coding control region (CR), and its gene arrangement is identical to those of most vertebr...
