Efforts to improve the production performance of clown loach in recirculate aquaculture system can be done by increasing stocking density and water discharge. This study aimed to analyze the effect of increasing stocking density and water discharge on production performance, stress response and water quality in order to obtain the best stocking density and water discharge to obtain maximum profit in a short time. A factorial completely randomized design with two factors, i.e. the stocking density of 1, 2, and 3 fish L-1 and the water discharge of 0,05; 0,10; 0,15 L s-1 was performed. The volume of water used in each aquarium was 48 L and using a ½ inch faucet stop to regulate the water discharge from the inlet pipe. Clown fish fed Tubifex sp. with a feeding frequency of two times a day according to the treatment for 60 days. The result indicates that there was no interaction between the two factors on production performance, payback period, and R/C ratio. Stocking density has a significant effect on specific growth rate, absolute growth rate of individual weight, feeding consumption rate and R/C ratio of clown loach. Stocking density and water discharge had an interaction on the visual color of pectoral and caudal fins of clown loach. Different stocking densities with the combination of water discharge in this study resulted that the water quality were within tolerable range for clown loach so that they did not experience stress, as well as high production and business performance. It is recommended to intensify clown loach with a stocking density of 3 fish L-1 and 0,15 L s-1‑ of water discharge.

Mud crab Scylla serrata is one of crustacean commodities with high economic value. One of the unsolved obstacles in mud crabs cultivation is crabs’ stress level caused by the declining water quality. The recirculating system is a method for maintaining water quality throughout the rearing period of culture crab. This system can use a variety of physical filter materials, such as zeolite, sand, and other materials. This study aimed to determine the amount of malang sand as a physical filter which positively affect the physiological responses and production performance of mud crabs. This research was carried out using a recirculating system with a completely randomized design conducted in five treatments with three replicates, i.e., malang sand with a weight of 0 kg (control), 5 kg, 10 kg, 15 kg, and 20 kg. The results proved that the best physiological response and production performance of mud crab was observed at malang sand treatment with a weight of 5 kg. This treatment showed specific growth rate, absolute growth rate for body weight, absolute growth rate for body length, and the survival rate of mud crabs with the highest value of 0.18±0.061%, 0.13±0.05 g/day, 0.0016±0.00006 cm/day, and 77.77%, respectively, yet it had the lowest feed conversion ratio of 3.76±004. In addition, the 5 kg treatment had water quality parameters in the tolerable ranges for mud crabs’ growth.

One of the factors that greatly influence the successful growth of cultivated fish is feed. The aim of this study was to examine the effect of iodine addition on the growth and survival rate of carp (Cyprinus carpio) seeds. This study used a completely randomized design (CRD) method with 4 treatments and 3 replications. 10 fish per unit each, with treatment P0 (feed without adding iodine), P1 (feed + iodine at a dose of 10 mg / kg), P2 (feed + iodine at a dose of 20 mg / kg), P3 (feed + iodine at a dose of 30 mg / kg). The results showed that there was no significant effect (p> 0.05) on the growth rate, feed conversion and survival rate of goldfish. So it can be concluded that the addition of iodine in feed supplementation up to a dose of 30 mg / kg does not have a significant effect on the growth rate of length and absolute weight, feed conversion, survival rate and iodine content in the body of goldfish (Cyprinus carpio). The best recommended dose of iodine for growth is 20 mg / kg of feed, although the results were not significantly different for growth. However, it can have an effect on the iodine content in the body of goldfish.

Background: Producing Thai native chickens through feed commercial is costly. To reduce the cost, native chicken could be fed with local plants or agricultural waste. Hyrrilla verticillate, a dominate macrophyte in Songkhla Lagoon, contain high crude protein and nitrogen free extract. Therefore, this research studied the use of Hydrilla verticillate in Thai native chicken diet on production performance, carcass characteristics and production cost. Methods: The experiment was executed in a completely randomized design (CRD) with 180 one-day-old commercial Thai native chicks. Four dietary treatments supplemented with 0%, 5%, 10% and 15% Hydrilla verticillata were formulated for three different phases of the experimental chickens: starter (1-4 weeks), grower (5-8 weeks) and finisher (9-12 weeks). Two chickens from each replicate were chosen for the carcass characteristics study. Result: During the starter phase, there was no notable effect shown among the chickens fed with the diet containing Hydrilla verticillata in terms of feed intake (FI) and body weight gain (BWG) (P greater than 0.05). The control chickens had best feed conversion ratio (FCR) (P less than 0.05), while the grower and the finisher periods, provided with different levels of Hydrilla verticillata, revealed no apparent differences (P greater than 0.05) concerning FI, BWG and FCR. Considering carcass characteristics, there were significant differences in live weight (LW) (P less than 0.05). But, no significant differences between treatments for hot carcass percentage, pectoralis majors, pectoralis minorstrip, thighs, wings, drumsticks and total edible carcass (P greater than 0.05). There were also statistical divergences regarding gizzard weight (GW) (P less than 0.05).
