Abstract

Pond bottom sediment conditions influence shrimp culture. As benthic organisms, shrimp are mainly on the surface of the pond bottom, so cultivation preparations related to improving sediment quality are essential. Pond bottom practice, such as drying, liming, and fertilizing, is common. However, in bottom pond conditions where total drying cannot be carried out, other treatments are needed, such as the addition of hydrogen peroxide. The purpose of this study was to determine the effect of adding hydrogen peroxide in pond sediments on the performance of shrimp growth and water quality. The study was conducted with five doses of hydrogen peroxide (0.25 mL, 0.5 mL, 1 mL, 2 mL) mixed with 350 g of pond soil sediment. Ten shrimps with an average weight of 0,27±0,03 g were put into the rearing container, which had been given pond bottom sediment according to the treatment. The results showed that the 2 mL hydrogen peroxide treatment gave the best results on the growth rate and average weight of Pacific whiteleg shrimp at the end of rearing. Water quality such as pH value, dissolved oxygen, and temperature were not significantly different between treatments. Hydrogen peroxide treatment can improve shrimp growth performance without affecting water quality during rearing.

Abstract

Highlight Research Cinnamaldehyde for shrimp Dynamics of Vibrio and the correlation with shrimp health status Green and yellow Vibrio bacteria in water, intestine, and hepatopancreas of shrimp Cinnamaldehyde decrease the number of green Vibrio bacteria   Abstract Disease can cause shrimp mortality and high economic losses caused by Vibriosis group. One alternative is using cinnamaldehyde which function as an anti-microbial and inhibit the production of toxins released by microorganisms. This study aimed to evaluate the administration of cinnamaldehyde on the dynamics of Vibrio bacteria and the health status of Pacific white shrimp fed with cinnamaldehyde-containing feed. This study used a completely randomized design (CRD) consisted of 4 treatments and 3 replications consisting of treatment K, A, B, and C which mean feeding without cinnamaldehyde, feeding containing cinnamaldehyde dose of 0.05%, 0.1%, and 0.2% respectively. Parameters included total bacteria (green and yellow Vibrio) in water, intestine, and hepatopancreas, as well as immune responses parameters, including total hemocyte count (THC), respiratory burst (RB), and phenol-oxidase (PO). All data were tabulated in Microsoft Excel 2016 and all statistical analysis was conducted in the SPSS v.22.0 software with one-way ANOVA followed by Duncan Multiple Range Test (DMRT (P=0.05). The results showed that the administration of cinnamaldehyde influences the dynamics of Vibrio and health status of shrimp. At the beginning and at the end of cinnamaldehyde administration, green and yellow Vibrio bacteria are mostly found in water, intestine, and hepatopancreas. The administration of cinnamaldehyde to Pacific white shrimp can reduce the number of green Vibrio bacteria both in the intestine and hepatopancreas as shown in treatments C and B. Cinnamaldehyde also affected the higher percentage of yellow Vibrio bacteria in treatments C and B compared to control (K). The highest immune responses of THC and RB were produced in treatments A and C compared to K. The decrease of green Vibrio bacteria and increased colonization of yellow Vibrio bacteria were correlated with immune responses. The best treatment in this study is treatment C.

Abstract

The research was conducted to determine the relationship between water quality and body length of arowana fish by measuring several water parameters including temperature, pH, dissolved oxygen and ammonia. In relation to length growth, calculations on SR, SGR are also carried out using ANNOVA. Direct laboratory scale observations were carried out by providing different feeds, including bloodworms, maggot, crickets and live fish with the water source for cultivation activities being well water. The results of observations in the field show that the growth rate of fish in length is influenced by the type of feed given. Giving bloodworms has the most effective value, next to live fish, maggots and crickets. This type of feed also affects the quality of the water used. To maintain success in ornamental fish cultivation, it is recommended to use water efficiently through integrated fish cultivation. Checking the water regularly as well as training of farmers on good management practices and integration is needed to ensure good water quality.

Abstract

The provision of quality and sufficient shrimp fry for production is largely determined by the management of maintenance during larval stadia. This study aims to obtain the best treatment of natural feed in the form of Spirulina sp. and Artemia sp. as feed supplements to improve the growth performance and survival rate of patin fish larvae. The experiment used a Complete Randomized Design consisting of 4 feed treatments and 3 replicates: A (Artemia sp. 100%), B (Artemia sp. 100% and Spirulina sp. 100%), C (Artemia sp. 50% and Spirulina sp. 50%), and D (Spirulina sp. 100%). The larvae with a density of 50 heads/L were kept in the aquarium and fed according to the treatment. The density of Spirulina sp. administered was 104–105 cells/mL maintained until day 7 according to the treatment. The parameters measured included growth performance, which included specific growth rate (SGR), survival (SR), absolute length growth (PPM), and analysis of larval digestive enzymes (amylase, lipase, and protease). The data were analyzed using one way-analysis of variance and continued with Duncan's Multiple Range Test with a 95% confidence interval using SPSS version 22.0. The results showed that the administration of Spirulina sp. produced better SGR, SR, PPM, amylase enzyme, lipase, and protease activities compared to the control (100% administration of Artemia sp.). The best treatment was given by 100% Spirulina sp. treatment. Keywords: Artemia sp., digestive enzymes, patin fish larvae, Spirulina sp.
