Abstract

Red tilapia (Oreochromis sp.) has been widely cultured throughout the world. Red tilapia is generally cultured in intensive system to increase production. However, many problems could be aroused from intensive culture including deterioration of water quality and fish health. Probiotics can be applied to overcome these problems. Probiotics contain beneficial microbes that can decompose metabolic products and stimulate the cellullar immune responses, thus enhancing the health and the growth of the fish and maintaining the quality of the water in ponds. The study aims to determine the effect of probiotics on the growth and survival of the red tilapia (Oreochromis sp.). The study was designed in a completely randomized design (CRD), which consisted of 4 treatments and 5 replicates. The treatment consisted of treatment A (control) without probiotics, treatment B (0.01 mL of probiotics / 30 L of water), treatment C (0.1 mL / 30 L), and treatment D (1.0 mL / 30 L). Analysis of variance (ANOVA) showed that administration of probiotics with different concentrations in the cultured medium had a high significant effect on the absolute growth of the red tilapia (P<0.01). The highest absolute growth (8,94 g) and survival rate (84%) were found in cultured media with probiotic dose of 1.0 mL / 30 L of water media.Keywords: Red tilapia, probiotics, growth, survival rate.

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

The current study was conducted to identify ectoparasites, infected organs, prevalence and intensity of ectoparasites in cultured common carp (Cyprinus carpio L.). Experimental animals were collected from ponds in 9 villages in 3 subdistricts in Sigi District. It was found that generally the common carp was infected by Dactylogyrus sp., Trichodina sp., Argulus sp., Epistylis sp., Chilodonella sp. and Ichthyophthirius multifilis. Infected organs consist of skin, fins and gills. The prevalence of ectoparasites per subdistrict was between 0.0 and 66.7 % and the intensity ranged from 0.0 to 3.0 individuals/fish. Key words: common carp, ectoparasites, prevalence, intensity.

Abstract

The objective of the research was to determine the effect of stocking density, feed type and feeding time on the growth and survival rate of juvenile whiteleg prawn (Penaeus vannamei) cultured in an extensive pond. A completely randomized design (CRD) was applied to a split-split plot design with three factor (stocking density as primary factor, feed type as sub-factor, and feeding time as sub-sub factor), giving 8 treatment combinations with 3 replicates (24 experimental units). Analysis of variance did not indicate any significant interaction between the effects of treatments on whiteleg prawn growth of any two or three factors (P > 0.05). Both stocking density (5 or 10 prawns/m3) and feed type (snails or corn) had a significant effect (P <0.05) on growth, while the effect of feeding time (day or night) was not significant (P > 0.05). Absolute growth of juvenile whiteleg prawn ranged from 2.16 to 7.03 g/prawn with a survival rate range of 60-100%.Keyword: whiteleg prawn, stocking density, feed type and feeding time.

Abstract

The pathogenicity of warm-water fish bacteria, Edwardsiella tarda in eel (Anguilla marmorata) was investigated.  This study was designed using a completely randomized design (CRD) with three treatments of E. tarda concentration (2.52 × 107, 105, 103 cfu/mL) and three replicates.   Regression analysis showed that the lethal concentration fifty (LC50) of E. tarda in eel was 2.56 × 104 cfu/mL. The mortality of eel in all treatments occurred 24 hours after injection. Clinical signs of disease in infected eel were melanization, inflammation, necrosis, pale liver, exopthalmus, ascites, and petechial haemorrhage.Keyword: Anguilla marmorata, Edwarsiella tarda, pathogenicity, lethal concentration.

Abstract

This study was conducted to determine the ability of aquaponic systems using different numbers of water spinach (Ipomea aquatica) clumps in reducing ammonia in tilapia (Orechromis niloticus) culture. This study was designed in a Completely Randomized Design (CRD) with 5 treatments and 4 replicates, namely Treatment A (without water spinach), B (3 clumps of water spinach), C (6 clumps of water spinach), D (9 clumps of water spinach) and E (12 clumps of water spinach). This study was conducted for 60 days in November-December 2018 at the Fish Reproduction Laboratory, Brawijaya University, Malang. The results showed that the use of different numbers of water spinach clumps in the aquaponic system had a significant effect (P<0.05) on the reduction of ammonia and nitrite concentrations, but had no significant effect (P>0.05) on the reduction of nitrate and absolute growth of tilapia. The highest ammonia and nitrite reduction concentrations were found in the treatment of 12 water spinach clumps 84.31% and 69.88%, respectively.
