Abstract

Cyprinus carpio is an economically crucial freshwater commodity in Indonesia and across the globe. Fish demand has a rising trend, which not in line with productivity. Innovation and aspects of food safety are the primary keys to increasing productive capacity. Therefore, the utilization of Manihot utilissima leaves as an alternative to improve national fish's productivity rate is a worthy consideration. They have multiple nutrients, including protein and fat needed by C. carpio seeds. This study aims to determine the optimal dose of M. utilissima supplementation to increase the productivity of C. carpio seeds. The methodology consisted of four treatments (0.5 mL/250 g, 10 mL/250 g, 15 mL/250 g) with four replications for 21 days. The outcome showed that P4 treatment (15 mL) could increase the relative growth rate by 21.10%/day, and it decreased the feed conversion ratio by 0.84. However, there is no significant effect on the survival rate. The study concludes that P4 treatment (15 mL) has positively increased the relative growth rate of C. carpio, and decreased its feed conversion ratio.

Abstract

The community's need for saline tilapia seeds (Oreochromis niloticus) until now still shows a significant increase, the development of tilapia aquaculture business is growing from the sector of breeding and enlargement. This study aims to determine the level of hatchability of saline tilapia eggs (Oreochromis niloticus) with different containers to provide alternatives to the community in using saline tilapia egg hatching containers This research was conducted at the Laboratory of the Fish Seed and Feed Production Technology Study Program of the Polytechnic of Indonesia Venezuela (POLIVEN) in March-April 2024. The research method used was an experimental design, namely a non-factorial Completely Randomized Design (CRD) consisting of 4 treatments, namely A (using a gallon), B (using a teapot), C (using a chicken drinking funnel), D (using a flower pot) each carried out 5 times with test parameters including egg hatchability, larval abnormality, and water quality parameters. Based on the research that has been done, the highest degree of egg hatching is in treatment C (chicken dringking funnel) with a value of 92% an the lowest is in treatment D (flower pot) with a value 51%. The highest larva abnormality is in treatment B (teapot). The annova test result showed that the application of different containers on egg hatchability had a significant effect on the hatching of saline tilapia eggs (Oreochromis niloticus). Based on the results of Duncan's further test showed that the treatment of chicken drinking funnel with 92% percentage is the best treatment compared to other treatments.Keywords:AbnormalityHatchabilityWater qualityTilapia Fish
