Phyto additives and their bioactive ingredients prove to be effective in enhancing the nutritional content of fish feed. This study aimed elucidate impact incorporating powdered herbal seeds (fennel, fenugreek, anise) as feed supplements at 5 g / kg on zootechnical performance, entire body chemical composition, hemogram, hepato-renal biomarkers, immune response, diversity intestinal microbiota European sea bass (Dicentrarchus labrax). During a 90-day feeding trial, cohort 240 with an average...
This study aimed to assess the genetic differentiation and relationship among five sea cucumber species from Red Sea in Egypt, namely Holothuria atra, H. impatiens, leucospilota, Actinopyga crassa A. mauritiana, using Inter Simple Sequence Repeated (ISSR) Start Codon Targeted (SCoT) markers. A collection of 100 specimens, with 20 individuals per species, was gathered for analysis. With ten ISSR primers, 135 amplified bands were detected, including 11 distinct species-specific bands,...
A quaculture farmers are concerned with achieving the highest growth rates regardless of condition water quality; therefore, farms set up in areas unsuitable parameters have been under-performing production and thus unsustainable (Stewart et al., 2013).Furthermore, anthropogenic actions led to degradation freshwater habitats concomitant depletion fish populations (Closs 2015; Gordon
Seasonal rhythms affect paddlefish farming practices due to the interactions among internal and external environmental factors in aquatic ecosystem, including different types of biological, chemical, or physical stressors.In present study, seasonal variations succession seasons during periods represent a striking force that reflects reality sustainable development under Russian aquaculture conditions.Five age groups (28, 29, 30; 26, 27, 28; 24, 25, 26; 19, 20, 21; 18, 20) were studied based...
Paddlefish (Polyodon spathula) facilities are centered in the regions of southern Russia, especially those located Delta-Volga River, where activities aquaculture observed intensively (Vasilyeva and Elnakeeb, 2019).Estuary Volga River North Caspian basin
