Abstract

Turi leaf (Sesbania grandiflora) is a natural ingredient with antibacterial compounds. This research was conducted from April to June 2022 at the Fish Nutrition Laboratory and the Laboratory of Parasites and Fish Diseases, Faculty of Fisheries and Marine, Universitas Riau. This study aimed to obtain the best dose of fermented turi leaves in feed seen from hematology before and after the challenge test with A.hydrophila. The method used in this study is an experimental method using a one-factor Completely Randomised Design (CRD) with five treatment levels, namely Kn: (no treatment), Kp: (no cure and infected with A.hydrophila), P1: (fermented feed containing 15% turi leaves, 85% soy flour), P2: (30% turi leaves, 70% soy flour), and P3: (45% turi leaves, 55% soy flour). Fish were reared for 46 days. The challenge test was conducted on day 32 with A.hydrophila bacteria at a density of 108 CFU/mL, as much as 0.1 mL/head. The results showed that fermented feed contained 45% turi leaves and 55% soybeans (P3). Wheat flour obtained total erythrocytes 2.51x106 cells/mm3, hematocrit 40.33%, hemoglobin 10.40 g/dL, total leukocytes 10.13x104 cells/mm3, phagocytosis activity 21.13%, survival rate 90%, and absolute weight growth 9.52g. Water quality parameters were temperature ranging from 27-300C, pH 5.9-6.2, DO 5.5-5.9 mg/L, and NH3 0.015-0.017 m g/L. Based on the results of the study, it can be concluded that there is an effect of adding fermented turi leaves to feed on the hematology of gouramy before and after the A.hydrophila bacterial challenge test has a significant impact.

Abstract

Moringa leaves (Moringa oleifera) contain flavonoids and saponins that can help improve fish health. Fish health and immune conditions can be predicted based on fish haematology. The study aimed to determine the effects of powder addition of Moringa leaves in fish feed pellets on the haematological disorders of saline tilapia. It was carried out from July to August 2022. Moringa leaf flour was mixed well with pelleted feed, and the dose of Moringa leaf flour was as follows: 0 (Control, without the addition of Moringa leaves), P1 (10 g/kg), P2 (15 g/kg), and P3 (20 g/kg). Fish were stored in round plastic containers (25 L, equipped with an aerator and circulation pump) for 42 days, 15 fish/container. During the study, fish were fed three times/day at satiation. Sampling was carried out twice, namely before treatment and at the end of the experiment (day 42). The results showed that adding Moringa leaf flour to fish feed pellets affected fish haematology. Fish fed with turmeric-enriched pellets showed a higher percentage of lymphocytes, increasing the fish's immunity. The best treatment was P2, which showed 81.66% lymphocytes, 7.11% monocytes, 8.66% neutrophils, and 2.55% thrombocytes. Data obtained showed that fish fed with Moringa leaf pellets had better haematological conditions than fish not fed with Moringa leaf pellets.

Abstract

Goldfish (Carassius auratus) at Maju Mapan Farm is one of the leading ornamental fish commodities with a high mortality rate due to disease. For this reason, this research aims to know about the type, prevalence, and intensity of ectoparasites at Maju Mapan Farm. The method in this research was random sampling for fish sampling 30 fish/pond. The type of parasites, prevalence, and intensity were analyzed descriptively and described in figures, tables, or graphs. This observation and identification showed that ectoparasites infected by goldfish at Maju Mapan Farm consisted of 3 types: Trichodina sp, Dactylogyrus sp, and Gyrodactylus sp. The types of ectoparasites that dominated both were Trichodina sp (96.11%), Dactylogyrus sp (3.61%), and Gyrodactylus sp (0.28%). Prevalence of ectoparasites was Trichodina sp (83.33%), Dactylogyrus sp (43.33%), and Gyrodactylus sp (6.67%). The intensity of ectoparasites were Trichodina sp (129 ind/fish), Dactylogyrus sp. (9 ind/fish), and Gyrodactylus sp (4 ind/fish). Trichodina sp. and Gyrodactylus sp. were commonly found in mucus, while Dactylogyrus sp. only infected goldfish in the gill organ. Prevalence and intensity of ectoparasites were found in goldfish with medium-stage infection at Maju Mapan Farm. The result of measuring water quality parameters was not optimal, causing ectoparasites to infect and multiply rapidly in goldfish at Maju Mapan Farm.

Abstract

ABSTRACT Fish quality is very important to determine the selling price of fish in the market; therefore, it is necessary to have special handling in storage so that the quality of fish does not decrease. Fishermen usually use styrofoam-insulated coolboxes to maintain fish quality. This study aims to determine the lowest temperature and temperature stability. This research was conducted in April-June 2022 at the Integrated Fisheries Laboratory, Faculty of Fisheries and Marine Science, Teuku Umar University. The method used is a quantitative experimental method using a completely randomized design (CRD) with 1 control, 2 treatments, and 3 replicates. Tests were carried out by measuring the temperature of the coolbox room filled with 3 kg of bulk ice and looking at temperature changes within 9 hours. The lowest temperature test results contained in the rice husk coolbox were 17.4°C, the corn cob coolbox had the lowest temperature of 19.3°C, and in the styrofoam coolbox (control), the lowest temperature obtained was 13.6°C. The temperature comparison between the styrofoam coolbox, rice husk insulation coolbox, and corn cob insulation coolbox shows that, in terms of the lowest temperature point, the styrofoam coolbox is still better than the rice husk and corn cob coolbox, while the rice husk coolbox is still lower in temperature than the corn cob coolbox.
