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

Jelawat fish (Leptobarbus hoevenii Blkr.) is one of the fish that is in great demand by the public. This production has problems with the body shape of fish fry which has many asymmetries and abnormalities. The cause of this cannot be ascertained, but the assumption is due to the influence of high pressure and water currents. For this reason, there needs to be clear research so that the exact cause is known. This study aims to see the fluctuations of asymmetry and abnormality in jelawat fish (L. hoeveni Blkr.) as a result of semi-intensive spawning. This research method is a sampling method on fish from semi-intensive spawning that is 2-3 cm in size. Then meristic measurements were taken and asymmetric fluctuations and abnormalities were calculated. The results of the study found that the value of number asymmetric fluctuations (FAn) ranged from 0.451 to 0. 864, while the magnitude asymmetric fluctuation (FAm) ranges from -0.044-0.053. For an abnormality of 1.05%, absolute length growth of 3.15 cm/head, absolute weight growth of 0.55 grams/head and survival rate of jellyfish larvae 99.5%.%, The results of water quality measurements were temperature range from 26-28.1oC, pH 6.7-7, dissolved oxygen of 4.7-5.3 mg/L, carbon dioxide of 5.3-8 mg/L and ammonia content in maintenance water of 0.001-0.011.

Abstract

Jelawat fish cultivation activities are still experiencing problems with low production. In order to increase the production of jelawat fish seeds during the grow-out phase, research needs to be carried out regarding the type of containers for the cultivation. This research aims to determine the best type of container for jelawat fish (Leptobarbus hoevenii) breeding regarding production performance and physiological responses. This study used a completely randomized design with four different treatments in rearing containers and three replications including aquarium (A), fiber tanks (B), concrete tanks (C) and floating net cages (D). The fish seeds used in this study were 2.76 0.15 cm long and weighed 0.17 0.17 g. During breeding process, the fish were given commercial feed with a protein content of 41% and air changes were carried out at 30% of the total air volume every 2 days. The parameters observed in this research include production performance, physiological responses, and air quality. The research results showed that different types of rearing containers had a significant effect on production performance parameters, total cholesterol, and hemoglobin. Total cholesterol and hemoglobin at the start of cultivation were 191 mg/dL and 11.6 g/dL, decreasing at the end of cultivation to 120.28-141.59 mg/dL and 9.03-12.83 g/dL. Air quality was still within the appropriate range for rearing jelawat fish seeds.Keywords:Aquariumsconcrete tanksfloating net cagestarpaulin pondsjelawat fish

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.
