Abstract

Catfish (Clarias sp.) is a freshwater fish species with high economic potential. One of the most important aspects of catfish aquaculture is hatchery technology. This process involves several critical stages, including broodstock selection, which applies breeding programs and phenotypic analysis to select broodstock with superior characteristics. Hormonal stimulation is also an essential method, in which broodstock are injected with hormones to accelerate gonadal maturation, using both natural and synthetic hormones. However, challenges in the spawning process remain, such as determining the appropriate hormone dosage and timing, as well as maintaining broodstock health. Environmental factors, including temperature, pH, and water quality, also influence spawning success and the quality of produced larvae. In addition, feed management and stocking density must be carefully controlled to support larval growth and survival. To increase the production of catfish seed, research and development of effective hatchery techniques are essential. This study aimed to improve the success and efficiency of OODEV hormone application through intramuscular injections at a dose of 0.5 mg per broodstock body weight, administered once at intervals of 3 days prior to spawning, in order to optimize fertilization rate (FR), hatching rate (HR), and survival rate (SR) of superior catfish larvae. The results showed that OODEV hormone administration influenced the reproductive process of catfish larvae. The use of OODEV hormone has potential to be applied in catfish aquaculture as an alternative method to enhance larval reproductive success.

Abstract

Tiger prawns produced in traditional ponds in North Kalimantan, especially Tarakan City, are a superior commodity susceptible to attack by pathogens. One way to prevent disease is to add probiotics. Probiotics are live microbes that help the host maintain microbial balance in the digestive tract. Prebiotics, conversely, are foods that cannot be digested by the host body but have a positive effect by selectively stimulating the growth of some bacteria in the intestine, such as Lactobacillus sp, thereby improving the host's health. To support the survival and growth of beneficial bacteria in the digestive tract, synbiotics combine probiotics and prebiotics in a balanced manner. It is hoped that administering probiotics and prebiotics will allow the growth of probiotic bacteria and other beneficial bacteria to improve the host's health. The research was carried out using a Completely Randomized Design (CRD) consisting of 5 feed treatments with three replications, namely 1: negative control consisting of commercial feed Feng Li-0, 2: positive control consisting of commercial feed Feng Li-0 added with a physiological solution and egg white, 3: prebiotic honey added to commercial feed Feng Li-0 along with physiological solution and egg white, 4: probiotic Lacto-B added to commercial feed Feng Li-0 along with physiological solution and egg white, and treatment 5: synbiotic honey and bacteria (Lacto-B) added to commercial feed Feng Li-0 along with physiological solution and egg white. This research aims to determine how effective prebiotics, probiotics and synbiotics are in producing black tiger shrimp juvenile survival. In this research, the synbiotic treatment showed the highest average survival value, final weight, and length in black tiger shrimp (Penaeus monodon) juvenile.
