Abstract

Red tilapia (Oreochromis niloticus) has its advantages compared to other cultivated fish. Namely, it can proliferate, is easy to breed, and is efficient for feeding. Besides, these fish can also tolerate changes in the aquatic environment. With these advantages, this fish is increasingly popular among cultivators. The need for tilapia fish seeds is increasing every year. The UPT of Freshwater Aquaculture Fisheries (PBAT) of Pasuruan Regency is one of the superior seed supply units for fisheries in East Java. The superior commodity is tilapia fish seeds. The purpose of this research is to know hatchery techniques for Red Tilapia (Oreochromis niloticus) at UPT PBAT Pasuruan Regency. The research was carried out directly through active participation in all Red Tilapia hatchery activities. The results are: Red tilapia hatchery at UPT PBAT Pasuruan Regency, uses natural spawning techniques with a male to female ratio of 1: 3. The spawning period is 21 days until harvest with two types of broodstocks, namely mature sires (2500-2700gr) and novice sires (300-500gr); The hatchery technique stages are media preparation, parent selection, spawning, larva harvesting, larva treatment, nursery, and seed harvesting; Water quality is still within the quality standard set by PP. 82 of 2001 with details of the average temperature of 29C, DO 7.7 mg / L, pH 8.325, and water depth of 50 cm.

Summary

INTRODUCTION

One type of freshwater fish that has great potential for cultivation is red tilapia (Oreochromis niloticus). The female parent has three channels: anus, a hole for removing eggs, and a urinary hole [3]. Red tilapia has its advantages compared to other cultivated fish. It can proliferate, is easy to breed, and is efficient for feeding. The need for tilapia fish seeds is increasing every year [4]. The superior commodity is tilapia fish seeds All broodstock in this UPT has been certified by the Fisheries Service. Throughout the year, it can continuously produce fish seeds, especially tilapia. Tilapia hatchery techniques are usually done naturally These fish can spawn all year round in the tropics. The spawning pond is made entirely of concrete, while the nursery pond is given a tarpaulin layer
