Abstract

High demand on   as consume fish nor as decorative fish, causes an increasing production. But, an obstacle occurs on production, due to reproductive characteristic of Common Carp fish. Different time on sperm and eggs production from male and female fish cause difficulties in breeding. Hence, it needed sperm preservation so the breeding could be done in whole year. Natural extenders are the solution to preserve fish sperm without side effect. The purpose of this study was to determine the effect of different types of extenders and different doses on the percentage of sperm motility and viability of carp (Cyprinus carpio) after storage This research was conducted at the Faculty of Fisheries and Marine Sciences, Universitas Brawijaya and the Freshwater Cultivation Installation (IBAT Punten), Batu, East Java. The method in this study was Complete Random Design (CRD) with 6 treatments, K (100ml lactate ringer); A (1ml cider + 99ml lactate ringer); B (1ml coconut + 99ml lactate ringer); C (1ml date juice + 99ml lactate ringer); D (1ml honey + 99ml lactate ringer); E (1ml sugar cane + 99ml lactate ringer). The results showed that the highest motility was obtained in the treatment of using date extract extender with a motility percentage rate of 77.66%; highest viability was obtained in the honey extract with 80.71%; and the highest fertility rate was obtained in the honey extract treatment with 72.67 %.

Abstract

Nitrogen plays a significant role in the growth and metabolism of microalgae. The purpose of this study was to investigate the influences of different sodium nitrate concentrations on growth, biomass, and biochemical profile in Tetraselmis chuii. Four different nitrate concentrations, 0.5, 1.0, 1.5, and 2.0 g/L NaNO3 were applied in T. chuii culture under a batch system. It was found that a low nitrate concentration of 0.5 g/L NaNO3 produced the highest specific growth rate and biomass concentration of T. chuii. On the other hand, increasing nitrate concentration led to an increase in chlorophyll a+b and carotenoid in T. chuii, with the optimum nitrate concentration found at 1.5 g/L NaNO3. Under the nitrogen limitation condition, protein content was significantly decreased, but lipid and carbohydrate content were highly accumulated in the cells. This study provides a unique phenomenon that low nitrogen concentrations not only produce higher biomass but also accumulate high lipid and carbohydrate content.

Abstract

The high feeding and the metabolic output of the fish in intensive aquaculture can cause various problem, such as poor water quality and slowing down the fish growth performance. Recirculating Aquaculture System (RAS) is a solution to maintain water quality. Unfortunately, the conventional mechanical filter in RAS such as japmat is inefficient. One strategy that can be applied is to use a hydrocyclone. This research aims to observe the fish growth performance in RAS pond using hydrocyclone mechanical filter and its comparison with the use of japmat. Research method was performed by comparing hydrocyclone and japmat in the pond with the RAS system. The research design is completely randomized design (CRD), with three replications in each treatment. The research was carried out through five stages, namely hydrocyclone set-up, RAS ponds set-up, water quality analysis, fish growth measurement, and statistical analysis. Based on the Independent Samples Test, the use of hydrocyclone mechanical filters has a significant effect (P<0.05) on the measured water quality parameters (DO, Temperature, pH, TDS, NH3) except for NO2. Hydrocyclone significantly affect Average Daily Growth and Specific Daily Growth parameters. Whilst, the Survival Rate and Feed Conversion Ratio parameters, it did not give significant effect

Abstract

Abstract. This study evaluates the multivariate relationship between shrimp pond water quality and vannamei shrimp growth using Canonical Correlation Analysis (CCA) with autocorrelation handling. Observational data was collected from 13 ponds (3 visits/pond; N = 39) in Banyuwangi (DOC 32–50; Nov 2022–Jan 2023), encompassing pH, temperature (Temp), dissolved oxygen (DO), Average Body Weight (ABW), and Specific Growth Rate (SGR). Diagnosis indicated residual autocorrelation, so CCA inference was made robust through cluster bootstrap per pond (B = 2000), partial CCA controlling for Visit, and within-approach (demeaning per pond), as well as being triangulated with mixed-effects models and GEE AR(1). The first canonical root was significant (ρ1 = 0.648; Wilks’ Λ = 0.541; p = 0.0015) and stable based on bootstrap (median ρ1 = 0.692; 95% CI 0.340–0.894). Canonical loading shows Temp as the main contributor on the water quality side (supporting pH, low DO), while SGR dominates on the growth side and is in the opposite direction to ABW. The redundancy index indicates a moderate level of cross-set explanation (Y from X = 13.7%; X from Y = 36.8%). These findings underscore the importance of daily temperature stability (supported by pH stability) and DO monitoring in shrimp farm management.
