Abstract

Palm kernel meal is considered very potential to be used as fish feed because it contains 15.43% crude protein. The problem by aquaculture is the imbalance in income obtained compared to production costs that have been incurred. This is because farmers depend on manufactured feed so that the price of commercial feed issued is high. The purpose of this study was to analyze the effect of different soybean meal and palm kernel meal feed substitutions on the growth and survival of catfish (Clarias sp). The study used a Completely Randomized Design with 3 treatments and 4 repetitions, consisted of three main treatments, namely: the first treatment (P1) feed based on a ratio of 80% soybean meal with 20% palm kernel meal and the second treatment (P2) feed based on 70% soybean meal and 30% palm kernel meal and (P3) feed based on 60% soybean meal and 40% palm kernel meal...The highest Weight gain value was found in P1 at 71.3 gr, followed by P2 at 51.5 gr, and P3 at 47.6 gr. The results showed that the highest RGR value was found in treatment P1 at 0.3% followed by treatments P2 and P3 at 0.2%. The best Feed Covertion Ratio (FCR) was found in treatment P1 at 4.31, followed by treatment P2 at 5.85 and treatment P3 at 6.22. The highest SR in treatment was found in treatment P1 at 91.7% followed by P2 and P3 at 90%.

Abstract

Vannamei shrimp (Litopenaeus vannamei) is one of the world's leading aquaculture commodities. Sukamara Regency is a leading regency for whiteleg shrimp cultivation in Central Kalimantan Province. Vannamei shrimp are euryhaline organisms, meaning they can survive in salinities ranging from 0.5 to 50 ppt, but optimal growth is generally reported to be in the range of 15 to 25 ppt. Shrimp's osmoregulation mechanism allows them to adjust their body's osmotic pressure to the environment, but this process requires extra energy. At salinities outside the optimal range, energy allocated for growth is diverted to maintaining ion balance, thus reducing growth rate. This study aimed to examine the effect of different salinities on the growth and survival of whiteleg shrimp. This research was conducted at the PSDKU Sukamara Fish Farming Laboratory and Workshop over a four-month period, from preparation to data analysis. The method used in this study was a completely randomized design consisting of 3 different salinity treatments and 4 replications. The highest growth performance results were found in P3 (salinity 20 ppt) followed by P2, and P1. While survival did not show any significant difference, with the highest survival rate in P3 treatment at 85%, followed by P1, and P2 at 75%. Water quality parameters showed that the water quality of cultivated fish was still in optimal condition, which showed that the temperature ranged between 26-28 oC, pH ranged between 7.8-8.2, and DO ranged between 10.4-10.9 mg/L.
