Abstract

Betok fish is an economically important fish and is very popular with the community but not many people have cultivated this Betok fish. For this reason, there needs to be an innovation in aquaculture technology so that Betok fish production increases. Stimulation of the work of pituitary hormones of broiler chickens to stimulate gonad maturation in Betok fish spawning to increase production due to overfishing. The purpose of this study was to test the effectiveness of broiler chicken pituitary extract on spawning betok fish (A. testudineus, Bloch) on latent time of ovulation, fecundity, and hatching rate. The study time for 30 days used 4 treatments 3 times, with P0 treatment: Control, P1 treatment: Broiler Chicken Pituitary Extract 0.2 ml/kg, P2 treatment: Broiler Chicken Pituitary Extract 0.4 ml/kg, and P3 treatment: Broiler Chicken Pituitary Extract 0.6 ml/kg. The results showed that treatment A. 0.2 ml / kg had a good effect on the ovulation latency time of betok fish, which was 8 hours 7 minutes, fecundity of 6618 eggs and hatchability of 94.67%. The results of water quality measurements showed that the temperature ranged from 28o-29o C, dissolved oxygen of 3.2-4.8 mg / L, pH of 7.3-7.7 and ammonia of 0.012-0.013 mg / L.

Abstract

The unusual body shape of jelawat fish fry can inhibit growth due to limited foraging movements and increases the risk of being preyed upon by healthier fry (cannibalism). This abnormality problem is usually only discovered when the seeds are around 1-2 months old. Increasing water levels can speed up the use of energy for finding food and breathing, causing more of the available energy to be used for movement rather than growth. This inhibits bone formation and body growth, causing abnormal fish growth. The aim of this research is to determine the optimal water level to increase the growth of jelawat fish seeds (L. hoevenii Blkr). This research used a Completely Randomized Design (CRD) with 4 different Water Height Treatments (A = 15cm; B = 20cm; C = 25cm; D = 30cm), and each treatment was repeated 3 times. The results of the research showed that water level had a significant effect on the growth of jelawat fish seeds. The optimal water height is 25 cm, with an abnormality rate of 1.05%, absolute length growth reaching 3.15 cm per fish, absolute weight growth of 0.55 grams per fish, and survival rate of catfish fry reaching 99.5%.

Abstract

. This study aims to determine the optimum density and to analyze the effectiveness of zeolite and activated carbon additives in the transportation of jelawat fish seed 2-inch for 12 hours. This research was conducted in March-May 2023. Transportation was carried out for 12 hours with the mode of transportation being a 4-wheeled minibus with travel routes starting from Jambi City to West Tanjung Jabung Regency. The experimental design used was a Completely Randomized Design (CRD) with 4 (four) treatments and 3 (three) replications, the treatments given were densities including: treatment A density of 100 individuals/container, treatment B density of 200 individuals/container, treatment C density 300 individuals/container and treatment D at a density of 400 individuals/container. In each container, 20 g and 10 g of zeolite and activated carbon were added. After being transported, the fish were maintained for 14 days. The results showed that during the transportation there were no fish deaths in all treatments so that the survival rate in all treatments was 100%. The average blood glucose level before transportation ranged from 56.3 – 57.3 mg/dL. The survival rate of post-transported barnet fish fry on day 0 to day 7 was 100%, while on day 14 the survival rate ranged from 90.1% -92.3%. Absolute length growth ranged from 1.30 cm/head – 1.38 cm/head. Absolute weight growth ranged from 0.30 gram/head-0.32 gram/head. Blood glucose levels at the start of maintenance ranged from 62.0-87.0 mg/dL. On the 14th day it ranged from 38.3 mg/dL-48.7 mg/dL. The water quality during the transportation and rearing process is still in the optimal range for barley fingerlings

Abstract

The low oxygen content in the rearing medium causes the larvae of jellyfish to become abnormal, growth is disturbed, and the survival rate is low. The study used a Complete Random Design (RAL) with 4 (four) treatments, namely A: 1 (one) aeration point, B: 2 (two) aeration points, C: 3 (three) aeration points, D: 4 (four) aeration points. Each treatment was carried out 3 times. The results showed that the difference in the number of aeration points given during the rearing of jellyfish larvae had a real effect on the abnormality and performance of the growth of larvae (Leptobarbus hoevenii Blkr). The best treatment for this study was treatment A with the number of aeration points used as much as 1 aeration point for the maintenance of jellyfish larvae (Leptobarbus hoevenii Blkr) in an aquarium with an Absolute Weight Growth (PBM) value of 0.492gr/head, Absolute Length Growth (PPM) 2.97cm/head, abnormality rate of 0.83%, Survival Rate

Abstract

The nursing phase of Jelawat Fish (Leptobarbus hoevenii Blkr) is a crucial stage in aquaculture, where preparing healthy and robust fry poses a significant challenge. The availability of fry for grow-out activities remains low, consequently limiting the production of Jelawat Fish. This study aims to determine the optimal stocking density under an intensive culture system by evaluating production performance and physiological conditions in a recirculating system for 40 days. The study was conducted using a Completely Randomized Design with four treatments and three replications for each treatment: A (5 individuals/L), B (10 individuals/L), C (15 individuals/L), and D (20 individuals/L). The results showed that high stocking densities significantly affected absolute weight gain (AWG), absolute length gain (ALG), feed conversion ratio (FCR), weight variation coefficient (WVC), and length variation coefficient (LVC). The weight gain increased from 0.50±0.09 g/individual to between 1.51±0.03 g/individual and 1.86±0.05 g/individual, while the initial length of 4.10±0.29 cm/individual increased to a final range of 5.36±0.05 to 5.72±0.06 cm/individual. The lowest FCR was observed at a stocking density of 10 individuals/L (1.33), whereas the highest FCR was found at 20 individuals/L (1.52). Water quality parameters remained within the optimal range for Jelawat Fish culture throughout the study. Therefore, a stocking density of 10 individuals/L is recommended as the best option to achieve optimal growth while maintaining stable physiological conditions in fish.
