Neuroanatomical distribution and partial sequence of cDNA encoding brain cytochrome P450 aromatase (P450aromB) in pejerrey Odontesthes bonariensis
Fish Physiology and Biochemistry - Tập 28 Số 1 - Trang 51-52 - 2003
The molecular cloning of a cDNA encoding the pejerrey brain cytochrome P450 aromatase (P450aromB) is described. This form shares higher identity to other brain aromatases than with their respective ovarian counterparts and the self ovarian aromatase. Tissue-specific expression of both aromatases was examined in pejerrey by RT-PCR. The immunocytochemical distribution of P450aromB was described.
Advanced broodstock diets for the mangrove red snapper and a potential importance of arachidonic acid in eggs and fry
Fish Physiology and Biochemistry - Tập 28 - Trang 489-491 - 2003
Mangrove red snapper fed advanced broodstock diets containing squid meal and squid oil exhibited higher hatching rates, cumulative survival and survival activity index than those fed a basal diet or a basal diet supplemented with mixture of antioxidants. On the other hand, fatty acid analyses of ovaries and fry of wild fish and eggs and larvae of broodstock fed raw fish revealed high arachidonic a...... hiện toàn bộ
Molecular characterization of superoxide dismutase and catalase genes, and the induction of antioxidant genes under the zinc oxide nanoparticle-induced oxidative stress in air-breathing magur catfish (Clarias magur)
Fish Physiology and Biochemistry - Tập 47 Số 6 - Trang 1909-1932 - 2021
Stress-induced changes in the affinity and abundance of cytosolic cortisol-binding sites in the liver of rainbow trout, Oncorhynchus mykiss (Walbaum), are not accompanied by changes in measurable nuclear binding
Fish Physiology and Biochemistry - Tập 12 - Trang 499-511 - 1994
Plasma cortisol levels and the number (Nmax) and affinity (Kd) of specific hepatic cortisol-binding sites were determined in rainbow trout subjected to chronic confinement stress for 14 days. Confinement significantly elevated plasma cortisol levels to 47.3 ± 13.5 ng ml−1 within 24h and although levels declined to 8.0 ± 3.0 ng ml−1 after 14 days, they were significantly higher throughout than leve...... hiện toàn bộ
Erratum to: Effect of taurine supplementation on hepatic metabolism and alleviation of cadmium toxicity and bioaccumulation in a marine teleost, red sea bream, Pagrus major
Fish Physiology and Biochemistry - Tập 43 - Trang 911-912 - 2017
Postprandial kinetics of gene expression of proteins involved in the digestive process in rainbow trout (O. mykiss) and impact of diet composition
Fish Physiology and Biochemistry - Tập 42 - Trang 1187-1202 - 2016
The impact of increased incorporation of plant ingredients on diets for rainbow trout was evaluated in terms of gene expression of gastric (gastric lipase, pepsinogen) and intestinal (prolidase, maltase, phospholipase A2) digestive enzymes and nutrient transporters (peptide and glucose transporters), as well as of postprandial levels of plasma glucose, triglycerides and total free amino acids.

Hormonal profile of growing male and female diploids and triploids of the blue tilapia,Oreochromis aureus, reared in intensive culture
Fish Physiology and Biochemistry - Tập 13 - Trang 209-218 - 1994
Triploidy as a result of thermal shock exposure of fertilized eggs decreases the growth rate ofOreochromis aureus as compared to their diploid controls, but this is due to the higher female ratio present in triploids (86%) and the lower growth rate of females. When females and males are considered separately, the growth rate is not significantly different in diploids and triploids. Since triploidy...... hiện toàn bộ
Plasma levels of immune factors and sex steroids in the male seahorse Hippocampus erectus during a breeding cycle
Fish Physiology and Biochemistry - Tập 43 - Trang 889-899 - 2017
To better understand the endocrine- and immune-response pattern during reproduction in a fish species having parental care behaviors and also to accumulate the endocrine- and immune-related data for future explanations of the low reproductive efficiency in seahorse species, the variations of immune factors and sex steroids in the plasma of the male lined seahorse Hippocampus erectus at different b...... hiện toàn bộ
A first observation of spermatogenesis in mature male scalloped hammerheads (Sphyrna lewini) from Zinkwazi, KwaZulu-Natal, South Africa
Fish Physiology and Biochemistry - Tập 47 - Trang 713-723 - 2020
Sharks are not only threatened, but also have a low fecundity as they are being overfished. The shark family, Sphyrnidae, consists of nine species of which three are found in South African oceans. One of the three Sphyrnidae species, the scalloped hammerhead (Sphyrna lewini) are the most common, but their biology and mode of reproduction are not extensively studied in terms of their reproductive b...... hiện toàn bộ
Effects of transportation on physiological indices and metabolomics of the large yellow croaker Larimichthys crocea
Fish Physiology and Biochemistry - Tập 49 - Trang 641-654 - 2023
The aim of this study was to investigate the survival rate, biochemical indices, and metabolome changes of the large yellow croaker after 48 h of live transportation. Two hundred and forty large yellow croakers (body weight: 23.4 ± 5.3 g, total length: 12.2 ± 0.7 cm) were used in this experiment. The transport buckets were filled with fresh seawater and the parameters of the water were a temperatu...... hiện toàn bộ
