Freshwater fish are a group that is especially susceptible to biodiversity loss as they often exist naturally in small, fragmented populations that are vulnerable to habitat degradation, pollution and introduction of exotic species. Relatively little is known about spatial dynamics of unperturbed populations of small-bodied freshwater fish species. This study examined population genetic structu...

A total of 117 species of freshwater decapod crustaceans are known from Brazil. Knowledge regarding the fauna of Decapoda from inland waters in the state of Bahia, northeast Brazil, is incipient. In spite of its wide territory and rich hydrographic net, only 13 species of limnetic decapods have been reported from that state. The objective of this contribution was to survey decapod crustaceans o...

The shrimp Palaemon serratus is a coastal decapod crustacean with a high commercial value. It is harvested for human consumption. In this study, we used Illumina sequencing technology (HiSeq 2000) to sequence, assemble and annotate the transcriptome of P. serratus. RNA was isolated from muscle of adults individuals and, from a pool of larvae. A total number of 4 cDNA libraries were constructed,...

Since 2022, the possibility of trawl fishing on Khanka Lake has been opened. In 2018 and 2020, accounting work was carried out using a beam trawl. Studies have shown that highest biomass in catches far eastern freshwater shrimp (Palaemon modestus), noodle fish, sharpbelly, bagrid catfish humpback. According to survey, stocks small fish species amounted 3,5–4,6 thousand tons. Taking into account...

In food deprivation assays, several different responses have been observed in crustaceans. However, studying energy reserves utilization among more than one species during the same starvation period has not yet been performed, particularly to discern whether the responses are due to intrinsic and/or environmental factors. We hypothesize that decapod species with similar feeding habits have the ...

Individual animals, including fish, often differ consistently in their behaviours, which is known as personality. An individual’s values on the five axes of personality, are activity, aggression, anxiety, boldness, and sociality, come together form syndromes. The major syndromes, proactive or reactive, characterize an expected behaviour. cunner wrasse, (Tautogolabrus adspersus), only warm-water...
