“…This correlation is also true for pangasius catfish in that smaller sized broodstock produce smaller sized eggs and larvae. Given the high fingerling demand for commercial production (Nguyen et al., 2013; Nguyen & Dang, 2009), pangasius catfish broodstock have been forced to mature faster and spawn at smaller sizes when reared under aquaculture conditions (Bui et al., 2010). Pangasius catfish, including those potentially used as broodstock for this study, are generally confined to pens containing a large number of fish and used as spawning broodstock when females and males are approx.…”

“…Herein, we report the effects of the T 4 and DOM on spawning profile and gonadal maturation and development in female rabbit fish. For many years in the field of aquaculture, scientists have attempted to develop techniques to induce reproduction in fish using hormonal stimulation (De Silva et al ; Nguyen et al ). In this study, we showed that T 4 exposure of female rabbit fish increased spawning performance.…”

Thyroxin (T4) is proven to have various functions in fish reproduction. In this study, we investigated oocyte maturation and spawning performance in the rabbit fish, Siganus guttatus, orally exposed to different doses of T4 (0.05, 0.25, and 0.5 mg/kg fish) during vitellogenesis. No statistically significant differences of reproductive characteristics were observed among the treatments. However, the group that was exposed to the dose of 0.5 mg/kg spawned after receiving a hormone injection. The findings suggest that feeding T4 during vitellogenesis did not advance oocyte maturation, but probably could induce spawning in rabbit fish. In a separate experiment, we investigated the effects of orally administered domperidone (DOM) on reproductive performances of the female rabbit fish. The study showed that oral administration of DOM during the early stages of the reproductive cycle had no significant effects on oocyte maturation and spawning performance. Overall, these findings suggest that DOM may not be needed for the induction of maturation and spawning of this species under aquaculture conditions. These practical investigations were conducted with a view to attempt reducing drug use, production costs, and support sustainable aquaculture.

“…world and has the potential to improve food security [2]. The success of aquaculture production depends on the all phase in aquaculture include broodstock holding, hatchery production of fry, nursing system, and grow out to market size [3]. Especially in fish larval farming on the hatchery, the obstacle is the availability and quality of live food at the right amount and size that suitable for the mouth size of the fish larva at the time of the first feeding.…”

Abstract. This study aimed to investigate the effect of the administration of rice washing water in culture medium on the growth performance of Daphnia sp. This research using three different doses of rice washing water i.e 1 mL/L, 3mL/L, and 5 mL/L. Daphnia sp. was cultured with an initial density of 20 ind/L. Observed parameters include growth parameters (population density, size and specific growth rate) and water quality. This result showed that a concentration of 3 mL/L created the highest population of Daphnia sp. density about 620±20 ind/L, number small size (young stage) 81.2%, and the highest specific growth rate about 56.68±0.55%. The water quality content of DO, temperature and pH during this study were in the good range of Daphnia sp. life and reproduction. The research has a conclusion that rice washing water can be used to nutritional sources of Daphnia sp. In the future, it is necessary to make further observations about the reproductive performance of Daphnia sp, given rice washing water through clone culture.Keywords: Live food, Population density, Rice washing water, Size of Daphnia sp., Specific growth rate
