Soluble antigen of Renibacterium salmoninarum (Rs) was detected by a polyclonal enzyme-linked immunosorbent assay (ELISA) at significantly higher prevalences in adult chinook salmon Oncorhynchus tshawytscha that matured in freshwater than in the same cohort of fish spawned after maturation in seawater. The cumulative results were consistent during 4 yr of comparison at the Little Port Walter Ha...

This paper reviews the current knowledge on shrimp broodstock nutrition with special reference to developments during the last decade. Biochemical studies and diet studies are discussed with the aim of identifying the nutrients that are important to sustain optimal shrimp maturation, reproduction and offspring quality. Additionally, an overview is given of the efforts to reveal the nature of ma...

High exploitation of the blue swimming crab (Portunus pelagicus) has significantly reduced its wild populations. The domestication process this species been started; however, breeding program not yet successful. Therefore, study aimed to examine reproduction performance intraspecific hybrids from Sorong (Papua) and Barru (South Sulawesi), Indonesia. P. pelagicus a bigger size, while better perf...

The production of cultured limpets is a recent research field contributing to aquaculture diversification, focusing on low trophic species while reducing the carbon footprint. Limpets are gastropods that colonize rocky substrates and mostly present tidal subtidal shores. This animal group in high commercial demand endangered several regions. has been traditionally challenging. most successful r...

The smooth clam Callista chione (Linnaeus, 1758), is distributed on sandy bottoms throughout the Mediterranean Sea and European Atlantic coasts over 0-180 m depth range (SALAS, 2011). This species is of great commercial interest in Spain, and is intensively exploited along the Catalan coast (DOGC, 2008). Catches have dramatically decreased over the recent years, threatening the biological and e...

The article describes the problems, which are of greatest interest for formation fish broodstock, such as process gameto- and gonadogenesis duration spawning cycles in broodstock reared artificial conditions. Under Research Experimental Aquaculture Complex BIOS CaspNIRKH formed paddlefish 63 females matured 2020. There were studied 11 born 2002 2003, whose roe was taken food purposes. following...
