Abstract The present study was aimed at comparing the brain size of mahseer (Tor putitora) in relation to their body weight and standard length, investigate potential impact rearing environment on development fish. three its subdivisions cerebellum (CB), optic tectum (OT), telencephalon (TC) were measured for both wild hatchery-reared data analysed using multiple analysis covariance (MANCOVA), ...

Naked mole rats (NMRs) are subterranean eusocial mammals, known for their virtual absence of aging in their first 20 to 30 years of life, and their apparent resistance to cancer development. As such, this species has become an important biological model for investigating the physiological and molecular mechanisms behind cancer resistance. Two recent studies have discovered middle and late-aged ...

  Gravid wild kutum broodstock, Rutilus frisii kutum, on their upstream migration to Valiabad River (northern Iran) were kept in captivity to allow them to ovulate (captive ripe). Then the impact of captivity on some reproductive and physiological parameters (i.e., plasma cortisol and glucose levels, fertilization percentage, gonadosomatic index and fecundity) were assessed and results were com...

Pedigrees are essential components in selective breeding programs to manage genetic diversity and obtain accurate parameter estimates ensure long-term response selection captive populations. High throughput cost-effective sequencing technologies has offered opportunities of using single nucleotide polymorphisms (SNPs) resolve penaeid shrimp pedigrees from mass spawning cohorts communal rearing....
