Tryptophan (Trp) is an essential amino acid, commercially available as a feed-grade product, and precursor to serotonin melatonin, which are both important molecules in stress mitigation. Meagre have high potential for marine aquaculture diversification but highly susceptible stressful conditions. This study aimed assess the role of dietary tryptophan supplementation meagre juveniles order mini...

Sciaenid fishes are important models of fish sound production, but investigations into their auditory abilities are limited to acoustic pressure measurements on five species. In this study, we used auditory brainstem response (ABR) to assess the pressure and particle acceleration thresholds of six sciaenid fishes commonly found in Chesapeake Bay, eastern USA: weakfish (Cynoscion regalis), spott...

Chromogranin A (CgA) has recently reported as stress marker in superior vertebrates. It is stored granules of the chromaffin tissue and released to bloodstream from adrenal medulla pituitary after situations. The objective this work was study chromogranin variation for acute chronic fish, aiming at determining if those proteins could be suitable markers. experiment conducted consisting two trea...

The effects of black soldier fly (Hermetia illucens) meal (HM) on gut morphology, microbial community, and humoral immune response was evaluated in meagre (Argyrosomus regius) juveniles. For that purpose, fish with 18.0±0.02 g were fed a control diet (CTR) without HM, 3 other diets including 10, 20 30% HM (diets HM10, HM20 HM30, respectively), replacing 17, 35 52% (FM), for 9 weeks. distal inte...
