Abstract

Fisherman is someone who works to do fishing activities in the sea with the aim of some or all of the proceeds sold. Fishermen have a high risk to their work, therefore the importance of safety and security culture in fishermen and the environment is very important to develop. The certification to fishermen through education and training of Basic Safety Training Motor Sailboats is an effort to improve the development of educational and economic aspects. In the aspect of education, certification will provide education to the community especially fishermen about the importance of safety and security while in the economic aspect is improving welfare and job search opportunities through certification in the community. The results of support for the development of the education sector and the economy are expected to increase the number of human development indexes, especially in central Java. Observations are carried out based on literature studies and then an approach to the implementation provided is through the implementation of community empowerment training programs. The human development index in Central Java Province which has increased by 0.20% in 2020 is expected to continue to increase, therefore observations are carried out in an effort to find out what things can support the sustainability of increased development, especially in economic aspects and education in the maritime field.

Abstract

Hematologic analysis of plasma proteins by testing for hemoglobin, erythrocytes, and leukocytes against ectoparasite infection in cages was carried out by taking samples of fish with consumption sizes of 15-20 cm. The aim of this study was to find out the amount of exposure to ectoparasites internally in the body of tilapia based on blood protein hematology test. Analysis of the data used is analysis of variance (ANOVA) with the aim of knowing the effect of sampling and the parameters tested. The results showed that the presence of infection identified normal hemoglobin levels of 7.438 g/dL, erythrocytes were quite low at 1.5605 x1012/L, this is the nutritional factor given to tilapia and leukocytes were still in normal condition, namely 61.985x109/L. The ectoparasites found were Streptococcus sp, Lernea sp, Aeromonas sp, and Trichodina sp. The effect of the value of plasma protein content in blood for hemoglobin and leukocytes is still in normal condition, but erythrocytes are below the normal point so that from internal factors of tilapia disease, hematological blood plasma protein affects tilapia disease, especially on erythrocyte variables that affect fish anemia to mass death. This is in accordance with the situation in the field where tilapia in the KJA (Floating Net Cage) experienced sudden and mass death in a short period of time even though previously routine controls had been carried out by cage cultivators. When fish experience stress, fish blood glucose levels will increase while fish blood plasma total protein levels decrease.

Abstract

Pangasianodon hypophthalmus is a freshwater fish that can grow well in dark condition. In no light condition, fishes are more responsive to feed provided. However, phytoplankton may not grow well, and as a consequence the water quality was poor and it negatively effects the fish health in general. The combination of biofloc and photoperiod manipulation systems is expected to improve the water quality as well as the fish health. To understand health status of the fish in general, the histological structure gill, kidney and liver was investigated. Sample were fixed in 5% formalin, paraffin processed and Haematoxylin Eosin stained. There were 2 factor, 3 treatment applied, namely natural (control), 18G (18 hours dark), 24G (24 hours dark) and 3 repetition. Parameter measured were survival rate and histological structure of gill, kidney, intestine and liver. Results shown that there are not difference of histological structure of the organs of fish reared under biofloc and manipulated photoperiod systems. There were light abnormalities in the gill, such as hyperplasia, hypertrophy, oedema and necrosis. There is no negative effect of biofloc system and photoperiod manipulation in structure of fish organ as there is only light abnormalities that can be cured when the water quality is good.

Abstract

The growth of giant gouramy in the pre-enlargement phase is very important, so the fish can grow and develop optimally until the enlargement phase. Water temperature is one of the many factors that directly affect the growth of fish. Water temperature significantly affects the rate of egg hatching of giant gouramy and the development of larval organs. The aim of this research is to determine optimum of water temperature on the growth of giant gourami fingerlings in pre-enlargement phase on controlled tanks. This research used a completely randomized design method with four treatments and two replications. The treatments in this study were: Control (maintenance without water heater); P1 (maintenance at 30 oC); P2 (at 32oC); and P3 (at 34oC). This research was conducted for 30 days by using giant gouramy fingerlings measuring 3,11± 0,14 cm with 50 ind/tank. The results showed that giant gouramy fingerlings was cultured at 32oC experience an absolute length growth of 5.29±0.21 cm, a daily growth rate of 3.32±0.07% and a survival rate of 94±2.82%. This indicates that the maintenance water temperature of 32oC is able to provide optimal growth for giant gouramy fingerlings in the pre-enlargement phase.
