Myogenesis of skeletal muscles in vertebrates is controlled by extracellular signalling molecules together with intracellular transcription factors. Among the transcriptional factors, the members of the myogenic regulatory family, including MyoD, Myf5, Myogenin and MRF4, play important roles regulating skeletal muscle development and growth. To characterize the gene structure and expression of ...

We have isolated and characterized several recombinant lambda phage clones carrying growth hormone (GH) cDNA of striped bass (Morone saxatilis). Nucleotide sequence and the predicted amino acid sequence of sbGH was determined from a recombinant clone carrying the longest cDNA insert. The sbGH cDNA encodes a pre-hormone of 204 amino acid residues. Comparison of the predicted amino acid sequence ...

Estrogen is an essential hormone for many reproductive and non-reproductive functions. The function of estrogen in the reproductive cycle of seabream (Sparus aurata), a protandrous hermaphrodite teleost fish, is complex but it is understood to be involved in sex inversion, a process that occurs in some individuals during the second reproductive season. Estrogen action is mediated by two estroge...

Aquaculture has been the fastest-growing area of worldwide food production and is becoming a vital component global economy to feed rising world population. Hence, directed toward continuing current level per head consumption, comprehensive aquaculture needs attain eighty million tonnes by 2050. However, some cultured marine fish species, such as salmonids, striped bass, gilthead seabream, well...

Phenols are plant metabolites characterised by several interesting bioactive properties such as antioxidant and bactericidal activities. In this study the application of a phenols concentrate (PC) from olive vegetation water to two different fresh products - gilt-head seabream (Sparus aurata) and chicken breast - was described. Products were treated in a bath of PC (22 g/L; chicken breast) or s...

A 120-day experiment investigated the new organic raw materials for Gilthead seabream (Sparus aurata) feeding on growth, nutritional parameters, digestibility, and histology. An control diet (CON) three diets with 100% materials—the rest of rainbow trout, visceral Iberian pig, insects as a protein source (TRO, IBE, INS)—were tested. After experiment, histology were measured. The CON diet-fed ob...

OBJECTIVE To investigate seasonal variations in tissue phosphorus (P) levels, P to protein ratio, and P to omega-3 fatty acid (ω3-FA) ratio in 2 species of fish that are commonly consumed in Lebanon. We aim to determine suitability for dietary management of renal patients. DESIGN AND SETTING Siganus rivulatus (rabbitfish) and Diplodus sargus (white seabream) were caught in traps off the coast...

The potential of the hepatic transcriptome expression profile evaluated in a sentinel feral fish to serve as an environmental biomarker was examined. Expression profiles of Lithognathus mormyrus individuals were exhibited using cDNA microarray and were related to the set of exposure conditions at their sites and dates of collection. Expression profiles of individual fish were reasonably cluster...

the black-striped pipefish, syngnathus abaster, is a species of the syngnathidae family. this study provides data on the morphometric, meristic and genetic structuring of the caspian sea pipefish, syngnathus abaster. eight morphometric characteristics based on total length and five morphometric characteristics based on standard length were analyzed. a total of 50 specimens were collected in bra...

This study was performed to determine the optimum level of soybean meal diets for two banded sea bream for growth performance, nutrient utilization, body composition and serum biochemistry. Two banded seabream were fed five experimental diets which were formulated replace fish meal by soybean meal at 0, 20, 30, 40 and 50%. Up to 40% of dietary fish meal was successfully replaced with no growth...
