Abstract

This study was conducted as an initial step in the domestication process of endemic fish in Jambi Province through an artificial feed adaptation approach. In addition, there is little data and research in Jambi Province that systematically discusses and tests artificial feed adaptation as part of domestication. This study aims to analyze the feed adaptation response in the cultivation of sepat fish (Trichopodus pectoralis), tambakan fish (Helostoma temminckii), and betok fish (Anabas testudineus) originating from the public waters of Kota Karang Village, Kumpeh Ulu District, Muaro Jambi as the initial stage of domestication. This study used a completely randomized design) with three treatments and three replicates. The treatments applied were different types of endemic Jambi fish, including sepat fish (T. pectoralis, treatment A), tambakan fish (H. temminckii, treatment B), and betok fish (A. testudineus, treatment C). The fish used in this study were wild fish obtained from public waters in Kota Karang Village, Kumpeh Ulu District, Muaro Jambi Regency. The average initial weight and length of sepat fish were 3.37±0.98 g and 6.32±1.52 cm, tambakan fish 7.65±0.74 g and 8.17±0.59 cm, and betok fish 8.03±1.13 g and 7.57±1.14 cm. Maintenance was carried out for 4 weeks, during which the test fish were fed artificial feed or commercial feed (39% protein). The feeding method was Ad-restricted. Feeding frequency is three times a day, namely in the morning, afternoon, and evening. The results of the study show that the SR value produced is 100% for all treatments. The highest PBM value is found in treatment A (sepat fish) at 1.34 g and the lowest PBM value is found in treatment C (betok fish) at 0.82 g. The highest PPM value was found in treatment A (sepat fish) at 1.12 cm, and the lowest PPM value was found in treatment B (tambakan fish) at 0.39 cm. The highest LPS value was found in treatment C (betok fish) at 6.40%/day, and the lowest LPS value was found in treatment A (sepat fish) at 3.54%/day. In general, the water quality parameters of the maintenance medium were suitable for the growth and survival of freshwater fish.

Abstract

Low fry quality and the lack of continuous fry availability are major constraints in Nile tilapia cultivation. One of the primary factors contributing to poor fry quality is the inadequate nutritional quality of broodstock feed. Egg stimulant is a feed additive containing multivitamins and minerals that can enhance egg production, improve egg quality, extend the spawning phase, and accelerate gonadal maturation. However, its effectiveness depends on species, broodstock age, and environmental conditions. This study aimed to evaluate the effectiveness of egg stimulant supplementation on larval productivity of Nirwana strain Nile tilapia at Ernawati Farm Galunggung (EFG) through broodstock feeding. Five treatments with three replications were applied, consisting of egg stimulant dosages of 0.25 g/kg, 0.33 g/kg, 0.5 g/kg, 1 g/kg, and a control. Observed parameters included the number of larvae produced per harvest and the daily growth rate of both female and male broodstock during the spawning period. Supplementation of egg stimulant to broodstock feed significantly increased the number of larvae produced per cycle, with the best performance observed in treatment P IV (1 g/kg). However, feed supplementation with egg stimulant did not result in a significant difference in broodstock body weight growth for either sex. Nevertheless, numerical improvements in weight gain were observed, indicating that the supplementation did not inhibit growth and supported the physiological performance of the broodstock

Abstract

The success of Nile tilapia (Oreochromis niloticus) cultivated is influenced by many factors, such as broodstock and fry quality, water quality, pond and feed management, and also the control of pests and diseases. The selection of appropriate spawning containers is critical, as it affects broodstock adaptation, comfort, behavior, and overall spawning success. This study aims to compare spawning performance of Nile tilapia in conventional earthen ponds and with hapa systems. A qualitative descriptive methodology was employed, with data collected at Ernawati Farm Galunggung (EFG), Tasikmalaya. Results demonstrated that larval productivity in the conventional earthen pond system was more stable than in the hapa system. Specifically, larval output over 10 spawning cycles with three replicates ranged from 30,000 to 94,000 individuals in the conventional system, compared to 10,000 to 110,000 individuals in the hapa system. The greater swimming space available in the conventional system likely facilitated nest building prior to spawning, contributing to increased productivity stability. In contrast, the restricted movement in the hapa system appeared to induce stress among broodstock, resulting in less consistent larval output. Larval survival rates were 100% in both systems, with larvae harvested at three days post-hatching.
