Abstract

Water fertility is the capacity or ability of waters to provide suitable nutrients for the life of phytoplankton so that it can produce optimum production. This research was conducted on June 2021 in the Waters of Bungus Teluk Kabung, Padang, West Sumatra. The purpose of this study was to determine the fertility level of Bungus Teluk Kabung waters based on the concentration of nitrate, phosphate, and the abundance of phytoplankton. The results of this study show that the fertility rate of Bungus Teluk Kabung waters based on the value of nitrate concentration, phosphate, and phytoplankton abundance in the waters of Bungus Teluk Kabung, Padang, West Sumatra, belongs to the category of waters with low fertility levels (Oligotrophic) to moderate fertility levels (Mesotrophic). The concentration of nitrate and phosphate has a weak relationship with the abundance of phytoplankton in the waters of Bungus Teluk Kabung and there isn’t any significant effect between the concentration of nitrate and phosphate with the abundance of phytoplankton in the waters of Bungus Teluk Kabung, Padang, West Sumatra.

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.
