Global molluscan aquaculture production is continuously increasing, dominated by five species, among which the Pacific cupped oyster, Crassostrea gigas, predominates. Hatchery production is accompanying this increase to assist consistent availability of juveniles for restocking, fishery enhancement, genetic improvements as well as for species diversification. Hatchery development contributes si...

A total of 523 bacterial strains were isolated during a 4-year period from mollusc hatcheries (flat oyster and clams) in Galicia (NW Spain). All of the strains were tested for their antibacterial activity against three larval pathogens (Vibrio anguillarum USC-72, V. neptunius PP-145.98, and Vibrio sp. PP-203). Of the isolates, 52 inhibited at least one of the target strains, and 11 inhibited al...

Second-generation sequencing technology has allowed a very large increase in sequencing throughput. In order to make use of this high throughput, we have developed a pipeline for sequencing and de novo assembly of multiple mitochondrial genomes without the costs of indexing. Simulation studies on a mixture of diverse animal mitochondrial genomes showed that mitochondrial genomes could be reasse...

Apoptosis is an important mechanism for the preservation of a healthy and balanced immune system in vertebrates. Little is known, however, about how apoptotic processes regulate invertebrate immune defenses. In the present study, we show that noradrenaline, a catecholamine produced by the neuroendocrine system and by immune cells in molluscs, is able to induce apoptosis of oyster Crassostrea gi...

Aquatic molluscs of three extensive nature reserves (Žabakor, Podtrosecká údolí, Údolí Plakánek) in the Český ráj Protected Landscape Area (northern Bohemia) were studied 2019. Altogether 33 mollusc species found at 40 sites including streams, fishponds, pools, and wetlands. Results compared with previous research. The occurrence endangered bivalves Sphaerium nucleus Pisidium amnicum was confir...

Monitoring physicochemical and biological parameters at regular intervals in marine ecosystems is necessary to protect water quality prevent pollution. This study aims review the scientific research articles published between 2000-2022 on heavy metal contents of mollusc species Dardanelles region. Levels metals were also discussed for human consumption by comparing existing data edible tissues ...

Distribution of molluscs in the eastern part of the Persian Gulf were studied during the PG-GOOS cruise (Oct-Nov 2012), using the 250 cm2 Van Veen grab for sampling. Sixty gastropod and 23 bivalve taxa in addition to one scaphopod taxon were identified. Gastropods constituted 80% of molluscs. The abundance of molluscs averaged 1398.36 (±261.95) ind./m2. Costellaria sp. was the most abundant ...

The aim of this study was to obtain a basic knowledge of the fatty acid compositions and consequently, determination of diet for Turbo coronatus by means of fatty acids biomarkers. Samples were collected during a year (April, July, October 2007 and February 2008) in coastal areas of Chabahar Bay in Oman Sea. Biomarker fatty acids revealed that diet of Turbo coronatus included phytoplankton, zoo...
