Using a semi-balloon otter trawl, crab fisheries in the main bays of Guangdong Province, China, were carried out seasonally . A total of 70 species were found, all belonging to the South China Sea Faunal sub region in the tropical India-West-Pacific Faunal Region. The clustering and nMDS ordination analysis revealed the existence of three groups. Group 1 included Hailing Bay and four bays to ...

This study identified the discard species generated by crab gillnet for targeting blue swimming Portunus pelagicus (Linnaeus 1758) in Banyuasin estuarine of South Sumatra, Indonesia. The fishing gear yielded discarded catch about 12% (25.68 kg) total weight (212.68 kg). For catch, 703 individuals represented 18 from 3 phyla (Arthropoda, Chordata, and Mollusca). crustaceans Charybdis helleri (Mi...

A gene encoding a putative GTP-binding protein, a TrmE homologue that is highly conserved in both prokaryotes and eukaryotes, was cloned from Thermotoga maritima, a hyperthermophilic bacterium. T. maritima TrmE was overexpressed in Escherichia coli and purified. TrmE has a GTPase activity but no ATPase activity. The GTPase activity can be competed with GTP, GDP, and dGTP but not with GMP, ATP, ...

Male swordtails in the genus Xiphophorus display a conspicuous ventral elongation of the caudal fin, the sword, which arose through sexual selection due to female preference. Females mate regularly and are able to store sperm for at least 6 months. If multiple mating is frequent, this would raise the intriguing question about the role of female choice and male-male competition in shaping the ma...

There is a close conceptual relation between the notions of religious disenchantment and scientific naturalism. One way resisting philosophical cultural implications image subsequent process can be found in attempts at sketching reenchanted worldview. The main issue accounts reenchantment rejection results that flies face good reason. Opposed to such naturalism which implies an entirely disench...

In this study we sequenced the genomes of three economically important swimming crabs Portunus trituberculatus, Charybdis japonica , and Callinectes sapidus using next-generation sequencing approach made a basic assembly. The species are characterized with high heterozygosity (>1.2%) repeat content (>50%). Genome comparative analysis revealed 40 long conserved fragments (>5...

In reviewing the work on the generic hybrids between Platypoecilus maculatus and X iphophorus hellerii, one is confronted by evidence which seems to point to a definite correlation between melanotic conditions in the hybrid fishes and their characteristic color pattern. In some cases, normal and pathological hybrids occur together in the same brood, born and reared in the same aquarium. But it ...
