Abstract

Humpback grouper Chromileptes altivelis is a marine fish that lives in tropical waters, especially in Indonesia. This fish has a high economic value and is the most expensive type of grouper in Indonesia. It can be used as ornamental fish or raised for consumption. Hatchery activities were started from brood rearing to produce productive broodstock, proper broodstock selection, multivitamin administration, and good environmental management. Humpback grouper was spawned en masse with a male to female ratio of 1:2. Fecundity of 1 female humpback grouper >300,000 eggs with a rematuration period of 20-30 days. Spawning using natural techniques accompanied by environmental manipulation, fish spawn for seven days during the dark moon. The number of eggs obtained was 560,000-2,000,000 eggs, with fertilization rate was 30-60%, and the hatching rate was 65-88%. The eggs that hatch into larvae were stocked with a density of 15-25 L-1. The larvae were transferred to a seed container at a size of 2-3 cm with a maintenance period of 40-45 days. Feeding at satiation using pellets measuring 1.1-2.0 mm with a protein content of 52-54% and 9-12% fat. Seeds were harvested at the age of 60 days when they reached a size of 5-6 cm, the survival rate was 3-5%.

Abstract

The issue of low survival rates and high mortality of larvae is commonly encountered during the rearing process. The success of larval rearing is significantly influenced by optimal stocking density, good water quality, and controlled feed management, all of which affect the growth and survival of the larvae. The aim of this applied research is to implement rearing techniques with different stocking densities and assess their effects on the growth and survival of galaxy rasbora (Danio margaritatus) larvae. This study employed a Completely Randomized Design (CRD) with four different stocking density treatments: 1 fish L⁻¹ for treatments KT1 and PT1, 2 fish L⁻¹ for treatment PT2, and 3 fish L⁻¹ for treatment PT3, each with three repetitions. The results showed that different stocking densities had a significant effect on the growth and survival of the larvae. The highest survival rate was observed in treatment PT2, with 96% survival. The control treatment (KT1), which used a semi-intensive system, achieved the highest absolute length growth of 6.87 mm and the highest daily length growth rate of 32.73% day⁻¹. The stocking density of 2 fish L⁻¹ in treatment PT2 demonstrated optimal results in terms of survival and growth.

Abstract

The freshwater lobster Cherax quadricarinatus is an aquaculture commodity with high economic value, yet it remains relatively unfamiliar to the general public. Nevertheless, market demand for this species has shown a significant upward trend, both domestically and internationally. In Indonesia, the increase of aquaculture production specially on freshwater lobster has not been sufficient to meet existing demand, primarily due to the limited availability of high-quality broodstock and the low reproductive capacity of female brood lobsters. One potential strategy to address this issue is the optimization of feed quality. This study aims to evaluate the effects of a dietary combination consisting of mung bean sprouts (Vigna radiata), white sweet potatoes (Ipomoea batatas), and commercial pellets enriched with vitamin E on the reproductive performance of female freshwater lobsters. The results indicated that the best feed formulation was observed in Treatment P3, which consisted of 25% mung bean sprouts, 50% Fengli 3 pellets + vitamin E, and 25% white sweet potatoes. This treatment accelerated gonadal maturation to 25 days and resulted in a fecundity of 467.33 eggs, a fertilization rate (FR) of 97.84%, a hatching rate (HR) of 92.70%, and a survival rate (SR) of 90.87%. The content of vitamins A, C, and E in mung bean sprouts is known to stimulate spawning and enhance embryo hatchability, while bioactive compounds in white sweet potatoes contribute to the synthesis of reproductive hormones such as estrogen and vitellogenin.
