Abstract Measurement of growth performances in fish is carried out in stressful and unnatural environment. The purpose of the present investigation was to compare the effect of four different water-borne anesthetic agents. The fish (Ave. wt. 400.3±7.12 g) were divided into four groups in the glass tanks (80×48×30 cm) containing 80 L of dechlorinated bore water. For the first group we used clove oil (CO) and anesthetic agents used for other three groups were as follows: second group- lidocaine 1% (LC), III groupisoflourane (IF), IV group-halothane (HT). During experiment, water quality parameters (to, pH, О2, and NO3) were recorded. The desired concentration of anesthetics was established andinduction time, maintenance and recovery time were recorded. In two groups out of four (LC and HT) time of induction was longer approximately with 1 minute and time of recovery was shorter with 30 seconds in comparison with other two groups (CO and IF) where the time for both was 3 minutes. It could be concluded that the anesthetic time for each of the protocols used was about 4-5 minutes and allowed to measure the growth performance. An effective and safe agent is 1% lidocaine used as a water-based anesthetic at 100 mg.L-1. Isoflurane can be used with caution in small carp because there is a risk of overdose. We recommend the anesthetic clove oil protocol.

Recirculating Aquaculture Systems

In Indonesia, the use of such recirculating aquaculture systems (RAS) is rapidly increasing. The purpose of this study was to investigate the growth, blood chemistry, and water quality of snakehead fish (C. striata) maintained in RAS at varied stocking densities. The RAS was established at the Bogor-based Research Institute for Freshwater Aquaculture and Fisheries Extension. The study employed a completely randomized study using 3 various densities: A). 1 individual L-1, B). 3 individual L-1 and c). 6 individuals L-1, each using three replications. The average weight and length of snakehead fish used is 1.50±0.63 g and 6.20±0.94 cm. Growth performances such as survival rate, weight, and length gain, food conversion ratio, specific growth rate, and final biomass were observed during the research. Blood chemistry parameters analyzed were blood glucose, triglycerides, and total protein. The water quality characteristics were evaluated: pH, temperature, dissolved oxygen, total ammonia nitrogen, nitrate, nitrite, and orthophosphate. The analysis indicates that snakehead fish's growth performances and blood chemistry parameters differed considerably (P<0.05) across all density treatments, with 3 individual L-1 showing the best growth performances. The RAS utilized in snakehead fish culture kept the water quality parameters steady throughout the study.

This study was conducted to assess the growth performances of cage reared GIFT strain of tilapia (Oreochromis niloticus) fingerling using length-weight (LW) relationship technique. Along with this, condition factor (K) of fish and   pond water quality parameters were also brought under this study to have broader understanding. For LW  relationship and K, a sample size of 120 fingerlings was made from randomly selected three different cages in a pond  at Tarala village in Kaharole Upazila of Dinajpur District, Bangladesh. The length-weight relationship of tilapia  fingerlings reared in cages managed by Adivasi people was significant. The value of correlation coefficient (r) and the coefficient of determination (r2) were 0.97 and 0.94 respectively. This suggests that growth of tilapia from fry to  fingerling was normal in cages. The condition factor of different size group of fish was almost closed to 2, indicating  fish health as satisfactory. All the water quality parameters including temperature, transparency, dissolved oxygen,ammonia-nitrogen, phosphate-phosphorus, nitrate-nitrogen and pH were within suitable range both in cages and  outside the cage in pond. About 5 phyla and 25 genera of phytoplankton from Bacillariophyceae, Cyanophyceae, Chlorophyceae, Euglenophyceae and Rhodophyceae groups and one phylum and 5 genera of zooplankton from Rotifera group were found in cage installed in ponds. These all indicate the growth of tilapia fingerling in cages was satisfactory which was technically sound for landless adivasi households.   DOI: http://dx.doi.org/10.3329/jbau.v10i1.12107   J.
