Abstract

The low survival value of gourami fish juvenile is because gourami is easily stressed. Changes in temperature in the rearing media environment can affect fish life and can even cause stress. Cortisol and blood glucose are indicators of early stress in fish which then naturally respond to the presence of environmental stressors by producing stress proteins such as mitogen-activated protein kinases (MAPKs). The purpose of this study was to analyze changes in growth, survival and p38 MAPKs of gourami fish juvenile reared at different temperatures. The working method used in this research is the experimental method. This research was conducted with 3 treatments and 3 replicates. The treatments given include (A) 27°C temperature treatment, (B) 29°C temperature treatment, (C) 31°C temperature treatment. Observations made were measurements of growth, survival, and p38 MAPK levels as well as physical and chemical parameters. The results of this study indicate that 31°C is the best temperature for gourami, the expression of p38 MAPK shows low distribution characterized by little brown color, survival rate of 80%, length growth of 1.8-2cm and daily growth rate of 0.21 g/day. During the study the pH in the treatments ranged from 7.3-8.1, while oxygen levels ranged from 4.2-7.7mg/l.

Abstract

Vaname shrimp is a fishery commodity with high economic value and a large export contribution. The maintenance period is long enough to make production results need to be considered directly. Feed as an important component that can affect growth, water quality, and production costs needs to be considered properly. The feed management program using blind feeding techniques has shown a significant impact on shrimp growth. The water quality factor does not have such a significant effect, except for ammonia which has increased due to the increase in the mortality rate of diseased shrimp. Water quality management with a blind feeding technique can be controlled with feed tests. The results of this observation were obtained directly from observation and active participation during the implementation of the street vendors.

Abstract

Goldfish (Carassius auratus) is a type of ornamental fish with various body shapes and colors. Goldfish in Indonesia are classified as high-economic fish, because they are in great demand by the public, especially ornamental fish hobbyists. The demand for goldfish is quite high, it is necessary to increase the goldfish hatchery activities so that the supply of seeds can be fulfilled with good quality and quantity. This scientific article aimed to describe the goldfish hatchery techniques and discover the obstacles in goldfish hatchery activities. This activity was carried out on 26 December 2022 – 30 January 2023 at BPPP Tegal, Central Java. Goldfish hatchery techniques include preparation of spawning facilities, parent selection, broodstock rearing, broodstock spawning, egg hatching, and water quality control. The fertilization rate of the oranda goldfish is 97%, the hatching rate of the oranda goldfish is 91.79%, the survival rate of the larvae of the oranda goldfish is 60.25% and the survival rate of the seeds of the oranda goldfish is 59.46%. The temperature during the breeding activity is 24-33°C, DO at 4-11 mg/l, pH at 6-8, and ammonia at 0-0.25 mg/l. Water quality at the breeding site is good and optimal for goldfish hatchery activities. Water quality control is usually performed by changing the water by 50% of the pond height.

Abstract

This study aimed to observe the culture technique of Chlorella sp. at BPTPB Cangkringan, Yogyakarta. Data were collected from direct observation by following the culture implementation and various literature studies in fresh water. From the observation result, the semi-mass scaled culture obtained the highest population density after 8-th day of culture at 2.970 x 104 cells/ml. The growth rates of Chlorella sp. in semi-mass scaled culture were 0.4298 x 104 cells/ml. The water quality of Chlorella sp. culture in semi-mass conditions was remained at 27-28oC, pH 7, and salinity 1 ppt. Nevertheless, the semi-mass scaled culture activity depends on the weather condition and good fertilizer quality to optimize the Chlorella sp. growth.
