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

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.

Abstract

Tanjung Jabung Timur Regency still has a relatively low fish production in Jambi Province, especially for freshwater fisheries, so there is still a high potential for increasing production. In order to increase fish production and the community's economy, it is necessary to conduct research related to the feasibility study of developing a freshwater fish farming area in the selected area. This research aims to select sites and assess the feasibility of developing freshwater aquaculture areas in Tanjung Jabung Timur Regency. The research was conducted over 8 months, from April to December 2022. There are three locations for the feasibility study of freshwater aquaculture area development, namely Talang Babat Village, Parit Culum II Village, and Rano Village, Sabak Barat Subdistrict, Tanjung Jabung Timur Regency. These three candidate locations are potential subdistricts in this regency that have generally been used (land use) for freshwater fish farming activities. The research was conducted by comparing the results of the suitability of the research parameters used between one candidate location and another. Several aspects of location suitability were used, including legal aspects, natural resources/technical aspects, artificial resources/infrastructure, socio-cultural aspects, and business/economic aspects. Based on the results of the semi-quantitative analysis, it was found that.
