Abstract

Siamese fighting fish (Betta splendens) is a freshwater ornamental fish that has a potential both in the domestic market and international market (export). Some studies on biological aspects of the Siamese fighting fish have been conducted.  However, information on the embryonic development of the fighting fish is lack.  The study aims to determine the stage of embryonic development in fighting fish. The experiment was conducted at the Laboratory of Aquaculture, Faculty of Animal Husbandry and Fisheries, Tadulako University, Palu. The results showed that the development of fish embryo can be divided into several stages, including cleavage, morula, blastula, gastrula, and organogenesis. The egg of the fighting fish was hatch in 35 hours after fertilization. Key words: Betta splendens, fish egg, embryogenesis, and larvae

Abstract

This study aims to determine the effect of stocking density on growth of Trout Grouper (Plectropomus leopardus) were cultured in the floating net cage. The study was conducted in Tolobundu Bay, Popidolon Village, Liang District, the residence of Banggai Islands, Central Sulawesi Province, during period of June to August 2011. Experimental organisms used were Trout Grouper (Plectropomus leopardus) with initial body weight of 200 g/head. Twelve 1 m x 1 m x 1m floating net cages with mesh sizes 1 inch were used for this experiment. Feeds given were trashed raw fishes amounted to 4-5% of the grouper biomass, fed three times daily. Experimental design used was completely randomized design (CRD) with 3 treatments, namely stocking densities of 15; 20 and 30 heads/m3, respectively, and with four replications. The results showed that the stocking density have a highly significant effect on the growth of Trout Grouper (Plectropomus leopardus), where the highest growth was performed by those cultured with stocking density of 15 heads/m3.Key words : stocking density, growth, Trout Grouper.

Abstract

This study aimed to determine the effect of extract tuba root (Derris elliptica) the length of time anesthesia carp (Cyprinus carpio). This study was conducted in March 2016, using the research material 180 carp fry and given a dosage of different tuba root extract, namely A (0.8 ml / 5 L of water), treatment B (1 ml / 5 L of water) , treatment C (1.2 ml / 5 L of water). Parameters measured were anesthetized seeds start time and duration anesthetized goldfish carp seed. Analysis of data using analysis completely randomized design (CRD) with a further test Significant Difference (LSD). The results showed that higher doses of tuba root extract the faster start time sedated and the longer duration of anesthesia seed carp. Treatment C (1.2 ml / 5 L of water) to give effect anesthetized fastest start time (28.25 minutes) and gave effect anesthetized longest time (205 minutes), whereas treatment A (0.8 ml / 5 L of water) to give influence anesthetized longest start time (41.10 minutes) and gave effect anesthetized fastest (111.17 min). The higher the dose of tuba root extract the faster start time sedated and the longer duration of anesthesia seed carp.Keyword: anesthesia, extract, tuba root, hatchery

Abstract

Some problems in Betta splendens cultivate activities were slow growth and mortality rates still high in the larval stage. Generally, Betta splendens larvae require a feed type based to the larval mouth. Some types of feed that can be given for larvae were Infusoria and yolk suspension. The study aims to find out the growth and survival rate of Betta splendens giving different first feeding. The study was conducted in January-February 2019 at Laboratory of Water Quality and Aquatic Biota, Faculty of Animal Husbandry and Fisheries, Tadulako University. The study used a Completely Randomized Design consisting of 3 treatments: A (infusoria); B (egg yolk); C (infusoria and egg yolk). Data were analyzed with ANOVA. The results showed that giving different first feeding did not significantly affect the growth of Betta splendens. The highest weight in the treatment of infusoria feed and the highest percentage of survival rate in the treatment of egg yolk.

Abstract

The problem that often becomes an obstacle in common carp culture is that the artificial feeding of common carp seeds has not yet had an optimal effect on survival and growth rates. due to the digestive system of seeds has not morphologic or physiologic differentiated, so the ability of seeds to digest feed still requires the addition of supplements such as probiotics. The research aims to analyze the effect of EM-4 probiotics addition on feed to growth SGR, FCR and survival rate of common carp seeds. The study was conducted in April to May 2019 at the Water Quality and Aquatic Biota Laboratory, Tadulako University. The study used a Completely Randomized Design consisting of 5 treatments and 4 replications. The treatments in this study were variations in the dose of EM-4 mixed addition in commercial feeding: A (0 ml/kg of feed); B (2 ml/kg of feed); C (6 ml/kg of feed); D (10 ml/kg of feed); E (14 ml/kg of feed). Data analysis used ANOVA and continued with LSD tests. The results showed that the use of EM-4 probiotics in feed significantly affected (P <0.05) on SGR, FCR and survival rate. Treatment D (10 ml / kg of feed) was the best treatment that resulted in SGR 0.014%, absolute weight growth of 7.775 g, FCR of 0.350 and 95% survival rate.
