Abstract

Udang vanname (Litopenaeus vannamei) adalah salah satu spesies udang yang saat ini banyak dikembangkan oleh para pembudidaya udang di Indonesia. Kegiatan produksi yang dilakukan dimulai dari persiapan wadah dan media, penebaran benur, manajemen pakan, manajemen kualitas air, monitoring pertumbuhan dan kesehatan, pengendalian hama dan penyakit, serta panen dan pasca panen. Metode pengumpulan data dilakukan dengan cara observasi dan wawancara sedangkan identifikasi masalah dilakukan dengan menggunakan diagram fishbone dan root cause analysis berdasarkan data key performance indicator yang diperoleh. Selama pemeliharaan, udang terinfeksi penyakit IMNV (Infectious Myo Necrosis Virus) yang diketahui berdasarkan gejala klinis yang dilihat secara visual pada tubuhnya serta udang mengalami kegagalan moulting yang menyebabkan kematian. Berdasarkan hal tersebut, terlihat dari data monitoring pertumbuhan dan hasil panen, seluruh wadah pemeliharaan tidak mampu mencapai target umur pemeliharaan. Pemanenan dilakukan sebelum umur 90 hari dimana size panen terbesar dihasilkan oleh wadah B1/P2 dengan size 48 ekor.kg-1 serta wadah C3/P2 dengan size 54 ekor.kg-1, sedangkan wadah lainnya menghasilkan size panen 94,6 – 222 ekor.kg-1. Data Survival Rate (SR) juga menunjukkan 4 wadah pemeliharaan tidak mencapai target (<85%) dimana SR terendah terdapat pada wadah A2/P1 dengan nilai 28,45%. Penelitian ini bertujuan untuk merancang usulan-usulan intervensi yang disusun bersama berdasarkan permasalahan-permasalahan yang dihadapi untuk meningkatkan produktivitas pada siklus selanjutnya.

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

This study aims to analyze the effectiveness and determine the dosage of soybean extract that can increase the motility of catfish sperm stored at preservation temperature. The research method used is RAL (Completely Randomized Design) with 4 treatments 3 replications where P1 0 ml soybean extract / 1 ml sperm, P2 0.3 ml soybean extract / 1 ml sperm, P3 0.6 ml soybean extract / 1 ml sperm, and P4 0.8 ml soybean extract / 1 ml sperm. The pH of catfish sperm before and after mixing soybean extract is 8. While after cryopreservation, the pH in treatment P1 is 5, treatments P2 and P4 are 6, and in treatment P3 with a value of 7. The volume of sperm used in treatments P1, P2, P3, and P4 before being diluted is 3 ml. The color of catfish sperm in P1 is milky white, while in P2, P3, P4 the color of the sperm is cream and smells fishy. Meanwhile, the viscosity level in P1 was thick, P2 was thin, and P3 and P4 were liquid. The results of observations of catfish sperm motility obtained the best value in treatment P3 (0.6 ml of soybean extract/1 ml of sperm) with a value of 2.6 (good). Meanwhile, the worst motility value was obtained in treatment P1 (without the addition of extract) with a motility value of 0.6, which is considered poor.
