Abstract

Abstract One of the problems in giant prawn cultivation is female giant prawns laying eggs during rearing. They will incubate their eggs for three weeks so that the energy from the expected feed for growth is used for egg development and other reproductive activities. Giving MPA hormone to giant prawns either by injection or oral could inhibit gonadal maturation and increase growth rate. The maturation process of the prawn ovary consists of the activation of some complex cellular mechanisms involving genes that regulate the stages of oocyte development. This study aimed to evaluate the response of gonadal maturity and the expression of the MrvWD-Kazal gene in giant prawns fed with a diet containing MPA hormone. The design used in this study was a completely randomized design with four treatments and five replications. The treatments were feeding a diet added with MPA with a concentration of 0 mg.kg-1 feed as control (K), 50 mg.kg-1 feed (P1), 100 mg.kg-1 feed (P2), and 150 mg.kg-1 feed (P3). MPA hormone at a concentration of 50-150 mg/kg feed could inhibit the gonadal maturation of female prawns. In 100 mg/kg of feed concentration showed the lowest gene expression level, indicating an inhibition of gonadal maturation molecularly. The administration of MPA hormone through the feed is a recommended method of aquaculture because it is more applicable and effective than by injection, even though it has a non-uniform impact on each individual. Highlight Research Administration of MPA hormone through the feed to female giant freshwater prawns can inhibit the level of gonad maturity. Expression of von Willebrand factor D (vWD) – Kazal gene were analyzed in different levels of prawn maturity Gonadosomatic index and gonadal histology confirmed that different levels of administration of MPA hormone through the feed could affect the gonad development. The administration of MPA hormone through the feed is a recommended method for aquaculture because it is more applicable and effective to inhibit early maturation of prawns.

Abstract

Graphical Abstract   Highlight Research The crossbred performance of the four tilapia strains showed diverse heterosis values, with some being better, worse, or the same as their parents. Crossbred of black tilapia produced the best growth and fecundity performance. A hybrid of Mozambique tilapia and black tilapia showed the highest mid-parent heterosis value on growth traits but produced negative heterosis on fecundity, biomass, and survival traits. Crossbred of black tilapia and Mozambique tilapia have the potential to be used as candidates for cultivation and performance improvement through selection, although there are depressions and crossover advantages that are not prominent.     Abstract Increased tilapia production is challenged by genetic decline. Hybridization efforts for performance improvement through a selection of the best parent and strain pairs were a promising option. The objective of this study was to evaluate the crossing of black tilapia, red tilapia, and Mozambique tilapia against the performance of fecundity, growth, and survival and estimate the value of heterosis. The experimental design used a completely randomized design with 3 replications with the treatment of different populations of crosses. The rearing activities were carried out in earthen ponds for 150 days with a stocking density of 10 fish/m2. The parameters observed included egg fecundity, growth, survival, and the value of heterosis. The results showed that the fecundity and growth values of crossbred black tilapia were significantly higher than others (p<0.05). The highest survival rate was shown by crossing pure strains of red tilapia. The hybrid of Mozambique tilapia and black tilapia (♀ MJ x ♂ NW) showed the highest mid-parent heterosis value on growth characters but produced negative heterosis on characters, fecundity, biomass, and survival. Overall, the crossbred of black tilapia (♀BS x ♂ NW) performed better than the inbred strains, with positive mid-parent heterosis in all characters measured. These results indicate that crossbreeding has the potential to be used as a candidate for cultivation and performance improvement through selection, although there were depressions, and the superiority of the crosses was not prominent.
