Abstract

Fluctuations in various pond water quality parameters can lead to low survival rates and suboptimal shrimp growth, ultimately affecting production targets. One of the factors influencing the water quality is the presence of phytoplankton. This study aimed to analyze the dynamics of phytoplankton abundance and composition, as well as their impact on the specific growth rate of Pacific whiteleg shrimp. The method consisted of water sampling, identification and calculation of phytoplankton abundance, water quality measurement, and shrimp growth sampling. The abundance of phytoplankton in the B5 pond ranged from 4.78±4.35 × 105 mL-1 cells. The abundance of phytoplankton in the B6 pond was approximately 4.14±2.14 × 105 mL-1 cells. Phytoplankton abundance in the B7 pond ranged from 5.05±3.57 × 105 mL-1 cells. The abundance of phytoplankton in all ponds fluctuated, and the composition of phytoplankton was in accordance with the standards for all three ponds. Based on the results of the Pearson correlation test, there was no direct relationship between phytoplankton abundance and the specific growth rate.

Abstract

Tilapia fish hatchery in Klaten uses the Dengkeng River as a water source for fish hatchery. The polluted water quality of the Dengklek River has an effect on the increasing number of ectoparasites that can infest tilapia seeds. The purpose of this study to evaluate the effect of ectoparasites on red tilapia in Klaten area, Central Java. This research was conducted at the Freshwater Fish Seed Work Unit, Loka Janti, Klaten. The research sample used red tilapia seeds Oreochromis niloticus measuring ±4-6 cm. Fish sampling was carried out randomly at the Freshwater Fish Seeding Work Unit Loka Janti, Klaten. Sampling was taken as many as 5 samples from 28 semi-permanent ponds. Physical and ectoparasite examinations were carried out on tilapia seeds. The data analyzed included water quality, epidemiology, parasite count measurements, specific growth rates, financial values, and Sensitivity Analysis. Ectoparasites can affect tilapia cultivation activities and cause losses. Fortunately, the ectoparasites in Loka Janti did not cause harm. Tilapia hatchery harvest size 2–3 cm with a selling price of Rp75.00 fish-1 resulted in an income of Rp426.062.70,00 and a profit of Rp71.814.554,00. The R/C ratio obtained is 1,20, and the payback period is 4,4 years.
