Effective management of rare species, including endangered native species and recently introduced nonindigenous species, requires the detection of populations at low density. For endangered species, detecting the localized distribution makes it possible to identify and protect critical habitat to enhance survival or reproductive success. Similarly, early detection of an incipient invasion by a ...

Reef-building corals begin as non-calcifying larvae that, upon settling, rapidly begin to accrete skeleton and a protein-rich skeletal organic matrix that attach them to the reef. Here, we characterized the temporal and spatial expression pattern of a suite of biomineralization genes during three stages of larval development in the reef-building coral Pocillopora damicornis: stage I, newly rele...

Purpose. Provide a comprehensive productive and biological characterization of carps the new selective breeding type, first generation — Nesvich zonal type in year life. Methodology. The study was conducted fish farms Lviv Volyn regions Ukraine. material for were young-of-the-years age-1 type. main parameters studied during test harvests growing season according to generally accepted methods fa...

This study, it was aimed to be enabling to use of fish scale as a bio-indicator for heavy metal pollution that is gradually increase in natural waters. For this purpose scaled carps, Cyprinus carpio (Linnaeus, 1758) were exposed to 7.5, 15, 30 and 60 μg L concentrations of trivalent chromium for 21 day and deformities appearing on the scales were examined under electron microscopy. It was found...

Recently, commercial nanometer sized silver is extensively used for its antibacterial effect; however, nanoparticles may also have ecotoxicological effects after being discharged into aquatic ecosystems. Nanometer sized silver can flow into water ecosystems, where it can exert a variety of physiologically effects in aquatic animals, including fish. The current research aimed to examine the effe...

4 1 Understanding the genomic signatures of population differentiation is fundamental to obtain a 4 2 comprehensive view of the evolutionary process of organisms. Grass carp is one of the most 4 3 important fish species in the world due to its significant value in aquaculture and worldwide 4 4 vegetation biocontrol. However, little is known about the contemporary population structure 4 5 and al...

Macrobrachium rosenbergii popularly known as 'scampi' has been expanding in India recent years. Scampi farming gained momentum after the set-back in shrimp farming due to disease outbreaks and other factors. The infrastructure available to produce shrimp seed and process the shrimp was helpful in providing support to scampi farming. The existing culture system includes both monoculture and poly...
