Abstract

Glass strain carp (Cyprinus carpio) is highly demanded by farmers due to its delicious, dense meat and fewer spines. To meet the increasing demand for carp, it is necessary to improve the efficiency of aquaculture. The season is known to stimulate one hormone production. The purpose of this study was to determine the effect of season (rainy and dry seasons) on reproductive hormones (follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone and estrogen, and interstitial cell-stimulating hormone)) in C. carpio glass strain. Idi research was conducted using the descriptive method by rearing fish in different seasons (rainy season and dry season). The results showed that the reproductive hormone of C. carpio strain glass increased during the rainy season. During the rainy season, changes in the environment and water flow patterns are detected by the fish's sensory system. The results showed that the highest hormones in a row were: ICSH hormone (12.82 pg/mL), FSH hormone (male: 3.73 ng/mL; female: 12.10 ng/mL), LH hormone (12.48 MIU/ml), testosterone hormone (9.27 ng/mL) and estrogen hormone (21.84 ng/mL). Further research is needed to observe the growth and abnormality of fish larvae produced in different seasons.

Abstract

Carp (Cyprinus carpio) is one of the most widely cultivated freshwater fish species worldwide. C. carpio is increasingly widespread with the presence of the C. carpio glass strain. This fish farming is inseparable from the influence of the season. The purpose of this study was to determine the sperm quality and fertility of glass carp strain produced in the rainy season and dry season. The method used in this research is descriptive. This research was conducted for 3 months (April - June 2024). Samples of glass strain carp C. carpio broodstock and research carried out at the Punten Aquaculture Fisheries Installation (IPB), with a total of 12 broodstock (6 males and 6 females with body size between 25-30 cm). The results showed that the sperm of C. carpio glass strain fish produced in different seasons showed different quality. The best sperm quality was produced in the rainy season with motility (70.44%), concentration (26.75 X 109 cells/ml), and viability (79.81%). However, the rainy season produced the highest abnormality (5.53%). Fecundity of C. carpio glass strain fish was highest in the rainy season reaching 10,875 grains. Further research is needed to determine the success of carp larvae in different seasons.

Abstract

The drying process is often a problem in maintaining the stability of probiotics and the quality of microcapsules in the processing of synbiotic microencapsulation. This study aims to optimize the temperature and drying time to maintain the core material's stability and the microcapsules' quality. The research design in this study was a completely randomized design with two factorials, namely drying temperature (30°C, 35°C, and 40°C) and drying time (2, 2.5, and 3 hours). The results showed that the highest viability and efficiency values ​​were obtained in the drying process at 40°C for 2 hours, which were 9.29 log CFU/mL and 98.10%. In addition, the water content and gel strength of the microcapsules obtained also showed optimal conditions. Based on the results obtained, it can be concluded that the drying process at 40°C for 2 hours is the best treatment, with the highest viability and EE values ​​and low water content values.
