A new species of Bregmaceros (Gadiformes: Bregmacerotidae) from the eastern Pacific Ocean, with comments on B. atlanticus and B. japonicus.

A new species of Bregmaceros is described based on a series of specimens from the eastern Pacific Ocean from near the Hawaiian Islands eastward to the California Current region. The new species bears considerable similarity in body shape and pigmentation to other overall darkly pigmented species with moderately high anal-fin counts (5159 in B. moseri) and modified prehaemal anal-fin pterygiophores (B.

Draft genome sequence of sp. from whole cantaloupe, with inhibition capacity against .

We report the draft genome sequence of a novel species, sp., isolated from a freshly harvested and untreated cantaloupe in North Carolina. The strain wild type exhibited inhibitory activity against the foodborne pathogen , including strains of diverse serotypes and genotypes, both on agar media and in biofilms.

Transcriptional regulation of prolactin in a euryhaline teleost: Characterisation of gene promoters through in silico and transcriptome analyses.

The sensitivity of prolactin (Prl) cells of the Mozambique tilapia (Oreochromis mossambicus) pituitary to variations in extracellular osmolality enables investigations into how osmoreception underlies patterns of hormone secretion. Through the actions of their main secretory products, Prl cells play a key role in supporting hydromineral balance of fishes by controlling the major osmoregulatory organs (ie, gill, intestine and kidney). The release of Prl from isolated cells of the rostral pars distalis (RPD) occurs in direct response to physiologically relevant reductions in extracellular osmolality.

Enhanced biodiversity of gut flora and feed efficiency in pond cultured tilapia under reduced frequency feeding strategies.

Feed constitutes 50-70% of total production costs of tilapia, one of the most widely cultured finfishes in the world. We evaluated reduced-feeding strategies for improving production efficiency of Nile tilapia (Oreochromis niloticus). In a 12-week pond trial, fish were fed daily, every other day, every third day, or not at all.

Leptin Stimulates Cellular Glycolysis Through a STAT3 Dependent Mechanism in Tilapia.

We assessed if leptin, a cytokine hormone known to enhance energy expenditure by promoting lipid and carbohydrate catabolism in response to physiologic stress, might directly regulate cellular glycolysis. A transcriptomic analysis of prolactin cells in the tilapia () pituitary rostral pars distalis (RPD) revealed that recombinant leptin (rtLep) differentially regulates 1,995 genes, . Machine learning algorithms and clustering analyses show leptin influences numerous cellular gene networks including metabolism; protein processing, transport, and metabolism; cell cycle and the hypoxia response.
