Abstract Black tiger shrimp (Penaeus monodon) is a commercially important species. It is reported to have low reproductive maturation rates in captivity. To improve the production of this species via sustainable aquaculture, genetic techniques are required to improve its maturation rates. However, to date, reports on P. monodon reproduction at a transcriptional level are limited. To […]

Abstract Black soldier fly (BSF, Hermetia illucens) meal is a prominent ingredient to keep up with the increasing demand of protein sources for aquafeeds. This study evaluated the digestibility of defatted BSF larvae meal (DBSFL) by indirect method, growth performance, haematological parameters, and carcass composition of tambaqui (Colossoma macropomum) fed diets containing DBSFL. The apparent

Abstract Environmental condition is a significant factor that directly affects the growth, metabolism and productivity of marine algae. This study examined the influences of diluted seawater on the growth, antioxidation capacity and accumulation of bioactive compounds of the marine macroalga, Sargassum muticum. Compared to the natural seawater (30 ppt, parts per thousand) control, the specific growth

Abstract The study explored the effect of increasing α-linolenic acid (LNA; 18:3n-3)-to-linoleic acid (LA; 18:2n6) ratios on the growth, fatty acid (FA) composition/deposition, hepatic expression of various genes responsible for fatty acid metabolism, fatty acid binding proteins (fabp1) from the level of DNA methylation and liver/intestinal histology in Chinese perch, Siniperca chuatsi. A total of

Abstract The study determined the combined effect of dietary l-carnitine (non-essential organic nutrient) and ractopamine (feed additive) on growth performance and nutritional composition of Labeo calbasu. To ascertain this, a 60-day feeding trial was carried out under a controlled condition where two hundred and twenty-five healthy L. calbasu fingerlings (avg. wt. 3.47 ± 0.1 g) were divided into

Abstract The abuse of antibiotics is creating a public health crisis and leads to the emergence of drug-resistant bacteria. Short-chain fatty acids (SCFAs) are the ferment products of gut microbiota with carbohydrate and play a pivotal role in host health. To date, there is very limited research on the potential anti-infection effect of SCFAs. In

Abstract The study appraised effects of Bacillus tequilensis (KF623287), through diets or water, on the growth and health status of rohu, Labeo rohita fingerlings. A basal diet (35% protein) was fed to the control (without B. tequilensis supplementation) and other experimental groups in triplicate for 60 days. B. tequilensis was added either to the diets at 1 × 107 cfu/g (D1),

Abstract The experiment was performed to examine the effect of Lactobacillus paracasei l61-27b (LP) isolated from Nile tilapia intestine on the growth rate, skin mucus and serum immune parameters and disease resistance. Fish (25.40 ± 0.33 g) were distributed into glass tank (150 litres tank−1) at 20 fish tank−1 and fed with different levels of dietary L.
