In the breeding process of high quality economy parent fish, the identification and the information storage and management of the parent fish are often through artificial way. This way takes workload too much and is hard to get high reliability. It is difficult to track and manage the breeding process of the parent fish well for us. Based on the RFID (Radio Frequency Identification, RFID) techn...

Environmental complexity and season both influence brain cell proliferation in adult vertebrates, but their relative importance and interaction have not been directly assessed. We examined brain cell proliferation during both the breeding and non-breeding seasons in adult male electric fish, Brachyhypopomus gauderio, exposed to three environments that differed in complexity: (1) a complex natur...

The aim of this study was using Bayesian approach via Gibbs sampling (GS) for estimating genetic parameters of production, reproduction and health traits in Iranian Holstein cows. Data consisted of 320666 first- lactation records of Holstein cows from 7696 sires and 260302 dams collected by the animal breeding center of Iran from year 1991 to 2010. (Co) variance components were estimated using ...

a larger proportion of energy intake for reproduction and also low food availability maydecrease the growth rate of other organs during the late stage of the gonadal development. themain goal of this study is to examine the biological characteristics and organs growth pattern inclupeonella cultriventris during the late stages of gonad development. samples were collectedby capturing 300-350 kilk...

To estimate the current significance of area for fish breeding, species composition and abundance young-of-the-year coastal zone Volga-Sviyazhsky Volga stretch Kuibyshev reservoir 2021, 2022 were considered. The work to assess young was carried out at 7 stations, depths less than 2 meters. number calculated per unit effort fingerling seine. Species diversity assessed using Shannon-Weaver index....

The zebrafish (Danio rerio) is used extensively as a model species for studies on vertebrate development and for assessing chemical effects on reproduction. Despite this, the molecular mechanisms controlling zebrafish reproduction are poorly understood. We analyzed the transcriptomic profiles of the gonads of individual zebrafish, using a 17k oligonucleotide microarray, to define the molecular ...
