Abstract

Streptococcus agalactiae are often the cause of Streptococcosis disease which attacks tilapia and results in mass death. Disease management needs to be done to control S. agalactiae infection using herbal ingredients and as an alternative to existing methods. The study consisted of two treatments (control and chitosan) of three repeats each. The treatment was tested in vivo by injection and challenged with S. agalactiae. Parameters observed include changes in morphology, fish behavior, and survival rates. The results of chitosan treatment on the parameters of changes in fish morphology and behavior showed milder infection than control, and a survival rate of 53.33%.

Abstract

The production of aquaculture in East Kalimantan Province in 2023 was recorded at 162,124 tons. This data indicates that the need for fish feed (pellets) is also very large. Meanwhile, it is known that the price of feed continues to climb. This study aims to observe the effect of the use of palm kernel meal, as an alternative feed ingredient, which is fermented using EM4 with different doses on the activity of digestive enzymes and the growth of gourami fish weight. The doses of EM4 used were 0 mL/kg (P1), 4 mL/kg (P2), and 8 mL/kg (P3). Based on the results of the analysis of variance, it was known that the inclusion of fermented palm kernel meal significantly (P<0.05) affected activities of amylase, protease, and lipase enzymes. The highest value of digestive enzyme activity was observed in P2 which produced amylase enzyme activity of 6.31 U/mL, protease 0.46 U/mL, and lipase 0.38 U/mL, and then followed by P3 which produced amylase enzyme activity of 4.76 U/mL, protease 0.39 U/mL, and lipase 0.35 U/mL. The lowest value of activity was observed in gourami treated with P1 which produced amylase enzyme activity of 4.048 U/mL, protease 0.36 U/mL, and lipase 0.31 U/mL. Analysis of variance also showed that fermented palm kernel meal had a significant effect (P<0.05) on the weight growth of giant gourami. The highest weight gain was produced by P3 (2.16 g), then followed by P2 (1.79 g), and P1 (1.21 g). The best feed conversion was produced by P2 (2.32), followed by P3 (2.94), and P1 (3.28).

Abstract

Pasuruan sea waters are one of the strategic waters in East Java Province. Ecologically, Pasuruan Waters is a habitat for various types of aquatic organisms including phytoplankton. The Pasuruan sea area is the estuary of the rivers in Pasuruan which carry household, factory and other waste. This is feared to result in a decrease in water quality which can interfere with the growth of phytoplankton in the waters. Phytoplankton is a biological parameter that can be used as a bioindicator to evaluate the quality and fertility of a waters. The purpose of this study was to determine the composition and abundance of phytoplankton in Pasuruan Waters, East Java. This study used a descriptive explorative method with data collection using a purposive sampling method. The results showed that 22 genera were found from 5 divisions, namely the Chlorophyta division (6 genera), the Baccilariophyta division (11 genera), the Miozoa division (1 genera), the Cyanobacteria division (3 genera), and the Dinoflagellate division (1 genera). The abundance of phytoplankton ranges from 961 – 1815 cells/liter. The diversity index is in the low category with a range between 0 – 0.153. The dominance index of 0.6 - 0.8 indicates dominance in the waters and shows that the community structure is unstable. The dominant type of phytoplankton is Bacillariophyta.  Keywords:  Composition, abundance, phytoplankton, Pasuruan waters

Abstract

The high cost of feed makes farmers more creative and innovative in making fish feed as an alternative feed, especially for sangkuriang catfish (Clarias gariepinus var.). Alternative natural feed can be given to reduce costs incurred during maintenance such as the results of decomposition by palm loose fruits. The purpose of this study was to determine the effect of alternative natural feeding with the palm loose fruits decay method on the growth of length and body weight of sangkuriang catfish (Clarias gariepinus var.). Palm loose fruits was taken from oil palm plantations in the Gunung Lagan area, Gunung Meriah District, Aceh Singkil Regency, Aceh Province. This type of research is a type of experimental research with the research data obtained analyzed using the one-way ANOVA test to see the differences between treatments (A) softened palm loose fruits, (B) palm loose fruits that have caterpillars on the decaying media and (C) control treatment, taken softened palm loose fruits for treatment (A) and (B) that have caterpillars, then given to catfish as much as 2 handfuls and spread evenly in the pond. For treatment (C) or control treatment, commercial feed type FF-999 is given as much as 2 handfuls. The results showed that the body weight of sangkuriang catfish in treatment A with 3 replications was 55.87 g, treatment B was 62.72 g and treatment C was 58.56 g. Meanwhile, the body length of sangkuriang catfish in treatment A with 3 replications was 12.49 cm, treatment B was 14.61 cm and treatment C was 13.55 cm. In treatment C, the average value is not much different from treatment A.
