Abstract

The demand for catfish increases every year, the production that occurs is not yet able to handle market demand. To meet the demand optimally, artificial spawning is carried out using gonadotropin hormones at different doses. This research aims to determine the right use of dosage in the artificial spawning process of sangkuriang catfish based on fecundity, FR, HR and SR. This research was carried out using 3 doses, namely for treatment P (0.1 ml/kg), Q (0.2 ml/kg) and R (0.3 ml/kg), each treatment was carried out in 3 repetitions. The results showed that the administration of gonadotropins achieved the highest fertility level in in spawning with a gonadotropin dose of 0.3 ml/kg of 62,150 grains. Meanwhile, the lowest fecundity value occurred in spawning with a gonadotropin dose of 0.1 ml/kg of 46,240 grains. The highest FR value was obtained when using a gonadotropin dose of 0.1 ml/kg which resulted in the highest FR value of 98.36% and the lowest FR using a gonadotropin dose of 0.3 ml/kg of 87.85%. The highest HR value was obtained at a dose of 0.1 ml/kg of 94.20%, and the lowest HR value at a dose of 0.2 ml/kg of 68.5%. The highest SR value was obtained at a dose of 0.1 ml/kg at 94.61% and the lowest SR value at a dose of 0.2 ml/kg of 54.39%. Based on the FR value at a dose of 0.1 ml/kg of 98.36%, for the HR value at a dose of 0.1 ml/kg of 94.61%. The results of the observations concluded that the use of gonadotropins with the highest fecundity value was obtained at a dose of 0.3 ml/kg with a total of 62,150 grains. The good dose of FR, HR and SR values for artificial spawning of sangkuriang catfish with gonadotropin hormone were found at a dose of 0.1 ml/kg where the fertilization rate (FR) value is 98.36%, Hatching rate (HR) is 94.2% and survival rate (SR) is 94.61%. The value of FR, HR and SR is influenced by environmental conditions and the care carried out. Because the condition of the larvae is still very vulnerable, the immunity is still weak, rudimentary organs are still in their infancy.

Abstract

Fortification of essential amino acids in self-formulated feed is a strategic approach to improve nutrient efficiency and reduce production costs in barramundi (Lates calcarifer) aquaculture. This study aimed to evaluate the effect of dietary lysine supplementation at 0.5% in self-formulated feed on growth performance and feed utilization efficiency. The experiment was conducted from March to June 2023 using a completely randomized design with two treatments: commercial feed as control and self-formulated feed supplemented with lysine, each with three replicates. Fish were reared under controlled conditions and fed to satiation. Observed parameters included weight gain, length increment, specific growth rate (SGR), feed conversion ratio (FCR), feed efficiency (FE), and water quality. The results demonstrated that lysine supplementation significantly improved growth performance and feed utilization. Fish fed lysine-supplemented feed showed higher weight gain (13.87±0.37 g) compared to the control (11.99±0.31 g), as well as lower FCR (1.76±0.10) than commercial feed (2.70±0.10). Feed efficiency was also significantly higher in the lysine treatment (56.8±3.17%) compared to the control (37.1±1.31%). However, no significant difference was observed in SGR between treatments. In conclusion, lysine fortification in self-formulated feed enhances growth performance and feed efficiency of barramundi, indicating its potential as a cost-effective and sustainable feeding strategy in aquaculture practices.
