Abstract:

This study aimed to identify the effect of stocking density on growth, feed efficiency, and survival during the transition from Peruvian grunts (Anisotremus scapularis) fingerlings to juveniles. Fingerlings were reared in triplicate for 63 days until reaching the juvenile stage, at 1000 fingerling·m−3 (low-density LSD, 0.79 kg·m−3), 2000 fingerlings·m−3 (medium-density MSD, 1.58 kg·m−3), and 3000 fingerlings·m−3 (high-density HSD, 2.37 kg·m−3), and production performance parameters were evaluated.

Striped eel catfish (Plotosus lineatus) are fish that live in coastal waters but there are also those that live in river mouths. This study aimed to determine the growth and survival rate of striped eel catfish fingerlings at different sizes in controlled media. This study used a completely randomized design (CRD) with three treatments (different sizes) and three replications, so there were nine experimental containers. The treatments used were treatment A: maintenance of fingerlings size (3.5-4.0 cm); treatment B: maintenance of fingerlings size (4.9-5.6 cm); and treatment C: maintenance of f

Abstract:

Abstract Intensive aquaculture is an attempt to farm fish at a high stocking density. High stocking density in Tor soro can affect growth, survival, and feed efficiency. Therefore, intensive aquaculture usually adopts several technologies and one of them can be found in the form of a recirculation aquaculture system. This study aimed to examine optimal stocking density supporting Tor soro performance under the recirculation aquaculture system. Four different stocking densities were used as treatments: 2 fingerlings/L, 3 fingerlings/L, 4 fingerlings/L and 5 fingerlings/L. The experiment followe

Abstract:

The growing public interest in catfish farming has resulted in an increased demand for catfish fingerlings. This trend has led many individuals to engage in the trade of catfish fingerlings, either as a primary source of income through the establishment of fisheries groups or as a supplementary means of generating additional revenue. This study aims to investigate the implementation of the catfish fingerling trading system based on volume measurement from the perspectives of Islamic law and positive law.

Different concentrations of lead nitrate solutions, viz., 1 ppm, 10 ppm, 40 ppm, 100 ppm, 120 ppm, 160 ppm, 200 ppm, 240 ppm, 300 ppm, 400 ppm and 500 ppm were prepared.

The impact of growing larvae and fry, with densities of 40-118 m-2 at harvest, on zooplankton was conspicuous only after Day 22 when Daphnia became rare and calanoid numbers were suppressed. Predation by fry caused reductions in the size of Moina, cyclopoids and calanoids found. An increase in Daphnia size, 'gigantism', occurred because of limitations in the mouth gape of the fry.
