Abstract

The cultivation of oysters has a significant historical background in the South Pacific region. The cultivation of pearls has been a significant source of livelihood for numerous island nations. Despite the significant cultural, dietary, and subsistence value of bivalve molluscs among Pacific Islanders, there has been limited advancement in the aquaculture of edible oysters in To enable a comprehensive assessment of the viability of cultivating edible oysters in Fiji, an estimation was conducted pertaining to the growth rate of mangrove oysters Magallana bilineata. A total of 105 oyster spat were cultured in Laucala Bay, Suva, Fiji, over the course of one year, from January 25th, 2021 to January 26th, 2022. The investigation documented exponential growth in oysters, with measurements of 87.3 ± 1.0 mm in length, 67.4 ± 0.7 mm in width, 49.8 ± 0.6 mm in depth, and 104.90 ± 22.6 g in weight. The findings of the study indicated the occurrence of positive isometric growth in relations to weight, length, width, and depth. The observed survival rate was 94%. The growth rates observed in oyster farming in Fiji exhibit similarities to those documented in other geographical locations, thereby providing a favourable indication for the progress of oyster aquaculture in the region.

Abstract

Tilapia is one of the fish that is widely cultivated in Indonesia. The obstacle to tilapia cultivation is high reproduction, which inhibits growth. An alternative to increase growth is by inhibiting gonad growth, so that feed energy is focused on somatic development. The aim of this research was to analyse the effect of velvet bean extract concentration on individual growth and gonad development of female tilapia fish and to determine the optimum concentration of velvet bean extract to increase growth and reduce reproductive activity in female tilapia fish. This study used a Completely Randomized Design (CRD) with the addition of various velvet bean extracts and compared with the control (without velvet bean extract). The use of velvet bean extract had a significant effect (p<0.05) on growth parameters such as length, weight, fecundity and egg diameter. The best treatment was found in treatment 3 (velvet bean extract 5 ml.kg-1 ) which resulted in growth in individual length of 16.1 cm, individual weight of 89.43 g, fecundity of 2206 and egg diameter of 1.11 mm. In addition, the dose in this treatment may reduce the reproductive activity of tilapia.

Abstract

The uncontrolled use of organochlorine insecticides in the agricultural sector has an impact on water pollution and threatens the lives of organisms in it. Pollutants can reduce water quality and interfere with the performance of fish organ systems, triggering stress and even death. The purpose of the study was to determine the sublethal effects of the organochlorine insecticide endosulfan on the level of oxygen consumption and histopathology of tilapia seed gills. The research was conducted at the Faculty of Fisheries and Marine Science, Universitas Airlangga, from March to May 2021. This study used a completely randomized design (CRD) experimental method. The treatment used was exposure to organochlorine endosulfan doses of 10%, 30%, 50%, and 70% with LC50-96 hours, which was observed for 28 days. Oxygen consumption data were analyzed by Analysis of Variance, followed by DMRT (Duncan's Multiple Range Test). While gill histopathology data were analyzed descriptively by comparing normal and abnormal gill histopathology. The results showed that the sublethal toxicity of the organochlorine insecticide endosulfan had a significant effect (p<0.05) on the level of oxygen consumption and had an impact on the histopathological condition of the tilapia seed gills. The types of gill damage found were oedema, hyperplasia, lamellar fusion, hemorrhage, and necrosis.

Abstract

Moina macrocopa is natural feed that commonly found in tropical waters. Ephippia can be stored and hatched at any time. Embryo stability can be protect by controlling the water content through coating technology. Honey solution can be used as a coating that have a osmotic regulation for prevent embryo from drought while ephipia entering the dormant stage. This research aims to determine the effect of concentration on the hatchability of ephipia and the survival of M. macrocopa nauplii. The research method used in this study was experimental with a completely randomised design (CRD) using five treatments and four replications. The results showed that coating ephipia using honey had a significantly different effect on the hatchability of M. macrocopa ephipia (p<0,05). However, the concentration of honey was not significantly different on the survival of M. macrocopa nauplii. Keywords : Ephipia, Honey, Moina macrocopa, Coating

Abstract

Increasing the number of heavy metals in the aquatic environment results in the accumulation of contaminants in fish body tissue, making fish an ideal bio-indicator of environmental pollution. The spleen included in the hematopoietic tissue contains macrophages. Macrophages form aggregates that contain pigments referred to melanomacrophage centres (MMCs). This research aims to analyse the metric profiles of MMCs on the common carp (Cyprinus carpio) spleen as a non-specific cellular immune response against mercury chloride exposure. This study used a Completely Randomized Design method with four treatments at different concentrations of mercury chloride (HgCl2) of 0 mg.l-1 , 0.01 mg.l-1 , 0.05 mg.l-1 , and 0.1 mg.l-1 . Each treatment was replicated five times. Data on the number and size of MMCs were analyzed by Analysis of Variance (ANOVA) and continued by using Duncan's Multiple Range Test (DMRT) to determine the differences between treatments. The result showed that the concentration of mercury chloride in water affects the metrics profile of spleen MMCs of carp. The number and size of MMCs of carp spleen increased at the concentration of 0.01 mg.l-1 and 0.05 mg.l-1 but decreased at the level of 0.1 mg.l-1 . The results suggest that the profile of MMCs as a non-specific cellular immune response can function as bio-indicators of environmental pollution.

Abstract

Fish transportation is a crucial step in maintaining fish quality during the shipping process from one region to another. The closed-wet system, which is commonly used for fish transportation, has several obstacles in the form of fish stress and mortality. Stressed fish generate primary, secondary, and tertiary stress responses. The purpose of this study is to assess the secondary stress response of tilapia during transportation by giving different doses of hydrogen peroxide. 3% hydrogen peroxide applied to water resulting in three different doses i.e. 0.3 ml.L-1 , 0.1 ml.L-1 , 0.08 ml.L-1 and without hydrogen peroxide used as control groups. Data was obtained by measuring blood glucose levels and the ventilation rate of tilapia. The results showed an alteration in blood glucose levels and ventilation rate of tilapia during transportation. Treatment with 0.1 ml.L-1 hydrogen peroxide gave the lowest glucose levels during 10 hours of transportation. Changes in ventilation rate of tilapia were observed in the treatment with 0.1 ml.L-1 of hydrogen peroxide which indicated miled stress conditions. It can be concluded that the optimal dose of hydrogen peroxide in the transportation process is 0.1 ml.L-1 of hydrogen peroxide.

Abstract

Betta sp. is an ornamental fish that is favoured by all ornamental fish hobbyists in Indonesia. Various strains of this fish have been produced by many farmers. However, almost all of the most popular strains are male. This study aims to determine the effect of different lengths of natural honey soaking on the masculinisation of hickey fish. The method used in this study was a completely randomised design with 4 treatments and 3 replicates. The treatment used in this study is the length of immersion (22 - 26 hours) of each treatment compared to the control (without immersion) which was then maintained for 60 days. The results of this study showed that immersion using natural honey on larvae in a 5 ml/L honey solution had no significant effect on masculinisation of hippopotamus. However, the best masculinisation was found with 22 hours of immersion at 63.6% and the lowest without immersion at 49.6%.
