Hypoxia-mediated inhibition of cholesterol synthesis leads to disruption of nocturnal sex steroidogenesis in the gonad of koi carp, Cyprinus carpio Fish Physiol. Biochem. (IF 2.242) Pub Date : 2020-10-09 Aritra Bera, Narinder Kumar Chadha, Subrata Dasgupta, Srijit Chakravarty, Paramita Banerjee Sawant
Reproductively mature koi carps (Cyprinus carpio) showed a prominent diurnal variation of sex steroids with sustained nocturnal rise. Exposure to chronic hypoxia (DO < 0.8 mg/l) disrupted nocturnal sex steroid production in koi carp gonads. Inhibition of sex steroidogenesis is linked to the down-regulation of HMG-Co A reductase (p < 0.05), which acts as a rate-limiting enzyme in the mevalonate pathway

Egg-sperm interaction in sturgeon: role of ovarian fluid. Fish Physiol. Biochem. (IF 2.242) Pub Date : 2020-09-14 Vitaliy Kholodnyy,Borys Dzyuba,Hermes Gadêlha,Jacky Cosson,Sergii Boryshpolets
Fertilization of freshwater fish occurs in the environment which negatively affects a lifespan of gametes mostly due to the osmotic shock; therefore, male gametes should reach the female gamete, as soon as possible. The existence of mechanisms controlling the encounter of gametes would be highly expedient in this case. By analogy with other species for which guidance was demonstrated, it is likely

Identification, tissue distribution, periprandial expression, and anorexigenic effect of spexin in Siberian sturgeon, Acipenser baeri. Fish Physiol. Biochem. (IF 2.242) Pub Date : 2020-08-14 Zhengzhi Tian,Shaoqi Xu,Mei Wang,Ya Li,Hu Chen,Ni Tang,Bin Wang,Xin Zhang,Zhiqiong Li
Spexin (Spx), an endogenous peptide, is considered to be a neuropeptide. In a few fish and mammals, it has been proved to play a role in the regulation of animal feeding. However, the possible mechanisms of spexin regulating food intake are mostly blurry in vertebrates including Siberian sturgeon. In this study, firstly, the coding sequence of spexin cDNA was cloned and sequenced in Siberian sturgeon

Impact of herbicide pretilachlor on reproductive physiology of walking catfish, Clarias batrachus (Linnaeus). Fish Physiol. Biochem. (IF 2.242) Pub Date : 2020-08-09 Rakesh Soni,Sushant Kumar Verma
Herbicide pretilachlor is widely used in paddy fields to control annual weeds. The present study has been carried out in walking catfish, Clarias batrachus, to evaluate the impact of herbicide pretilachlor on reproductive physiology after chronic exposure. Based on the median lethal concentration value (96 h), fish were exposed to three nominal test concentrations of pretilachlor ((SL-I (1/20th LC50)

Comprehensive physiological and transcriptomic analysis revealing the responses of hybrid grouper (Epinephelus fuscoguttatus♀ × E. lanceolatus♂) to the replacement of fish meal with soy protein concentrate. Fish Physiol. Biochem. (IF 2.242) Pub Date : 2020-08-07 Yan Chen,Wenkan Liu,Jun Ma,Yaorong Wang,Hai Huang
Plant proteins are suitable and alternative to fish meals (FMs), with less cost compared with that of all other types of fish feeds. In recent years, soy protein concentrate (SPC) has emerged as a cost-effective alternative to FM; however, little is known regarding the effects of dietary SPC on general fish physiology and well-being. This study aimed to perform comprehensive physiological and transcriptomic

Dietary exposure to ochratoxin A reduces growth performance and impairs hepatic purinergic signaling in tambaqui (Colossoma macropomum). Fish Physiol. Biochem. (IF 2.242) Pub Date : 2020-08-07 Matheus D Baldissera,Carine F Souza,Jefferson A da Silva,Danilo C Barroso,Eduardo M Glória,Bernardo Baldisserotto,Adalberto L Val
The practice of replacing costly animal-derived proteins with more economical plant proteins has augmented the risk of mycotoxin contamination in fish feeds, including contamination with ochratoxin A (OTA). OTA is a secondary metabolite produced by molds commonly found in fish feeds that causes impairment of performance in several fish species and some hepatic biochemical alterations. However, the

Effects of ammonium sulfate on stress physiology and innate immunity of Western mosquitofish (Gambusia affinis). Fish Physiol. Biochem. (IF 2.242) Pub Date : 2020-08-05 Elyse Schnabel,Travis E Wilcoxen
Fertilizers increase yield of crops but may have unintended negative effects on fish as a byproduct of runoff into bodies of freshwater. The objective of this study was to determine if environmentally relevant concentrations of an ammonium fertilizer impacts stress and innate immunity in Western mosquitofish (Gambusia affinis). The mosquitofish were exposed to different concentrations of ammonium sulfate

Valine acts as a nutritional signal in brain to activate TORC1 and attenuate postprandial ammonia-N excretion in Chinese perch (Siniperca chuatsi). Fish Physiol. Biochem. (IF 2.242) Pub Date : 2020-08-04 Jie Wang,Xu-Fang Liang,Shan He,Yan-Peng Zhang,Jiao Li,Kang Huang,Lin-Jie Shi,Ping Ren
An emerging concept is that the hypothalamic nutrient sensor can regulate peripheral energy metabolism via a brain-liver circuit. Valine is an essential branched-chain amino acid (BCAA) that drives intracellular signaling cascades by the activation of target of rapamycin complex 1 (TORC1) which is critical to protein metabolism in mammals. However, in teleost fish, it remains scarce in this area especially

Effects of MC-LR on histological structure and cell apoptosis in the kidney of grass carp (Ctenopharyngodon idella). Fish Physiol. Biochem. (IF 2.242) Pub Date : 2020-07-25 Li He,Lin Liu,Changgao Lin,Jiming Ruan,Ximei Liang,Ying Zhou,Lili Wei
Microcystin-LR (MC-LR) is a well-known hepatotoxin; however, increasing evidence suggests that it might induce kidney injury. Grass carp (Ctenopharyngodon idella) is one of the most important farmed species and may be affected by MC-LR releasing into waterbody during cyanobacterial bloom. Here, this present study aimed to explore the nephrotoxicity of grass carp by MC-LR. The grass carp received a
