Growth is a priority trait from the point of view of genetic improvement. Molecular markers linked to quantitative trait loci (QTL) have been regarded as useful for marker-assisted selection in complex traits as growth. Polymorphisms have been studied in five candidate genes influencing growth in gilthead seabream (Sparus aurata): the growth hormone (GH), insulin-like growth factor-1 (IGF-1), m...

In recent years, with the advent of next-generation sequencing along with the development of various bioinformatics tools, RNA sequencing (RNA-Seq)-based transcriptome analysis has become much more affordable in the field of biological research. This technique has even opened up avenues to explore the transcriptome of non-model organisms for which a reference genome is not available. This has m...

Abstract Oryzias woworae , one of the endemic ricefish species from Sulawesi, is threatened with extinction in their habitat. Domestication aquaculture way to preserve conservation these fish. The success factor for cultivation adaptation immature broodstock a controlled environment gonadal maturation. Adaptation performance after closed system transport first study O. at start an adjustment re...

The Ciparanje inland aquaculture area has emerged as a hub for breeding ornamental fish, with koi fish being prominent species. increasing demand led to surge in businesses. What sets apart from some other species is their ability breed throughout the year, unaffected by specific seasons. However, natural habitat, typically spawn at onset of rainy season, triggered enticing aroma soil. growth i...

Betta fish are freshwater ornamental that very popular and have quite high economic value, but the reproductive process still depends on spawning season, so an increase in potential is needed. The experiment was conducted order to determine role of each induction Oocite development (Oodev) hormone diet betta female final maturation morphology gonads. Completely randomized design (CRD) with one ...

In the present study, biological function of recombinant gonadotropin-releasing hormone associate peptide (rGnRH) was tested for induction ovulation and spawning in Sterlet sturgeon (Acipenser ruthenus) broodstock. For this purpose, broodstock were divided into four treatments treated with following preparing procedure: 0.9% NaCl (C); 2.5 ?g kg body weight?1 (BW) LHRH-A2 (luteinizing hormone-re...

Many new classes of Polymerase Chain Reaction (PCR) -based genetic markers have been developed over the last decade. Of these, microsatellite markers are widely regarded as one of the most useful identifi ed so far1,2,3. The signifi cance of microsatellite markers derives from their abundance in the genome, single locus nature, simplicity of assay, high levels of allelic diversity, mendelian in...

In this study, age-dependent changes of sperm quality parameters in Rutilus frisii were investigated. Also, fertilization capacity of breeders was tested using two age groups of males (3 and 4 year old breeders) and one female group (i.e. 4 year old breeders). For fertilization trials, the breeders were crossed randomly among age classes. Between the two age groups, spermatological parameters d...
