Optimization of Hormone for Artificial Breeding and Seed Production of Clarias batrachus (Linnaeus, 1758) Under Captive Condition
No full textAims: The study aimed to develop brood stock of Magur (Clarias batrachus), artificial breeding and seed production under captive condition using growth hormones in north-eastern Bangladesh.
Study Design: Fifteen pairs of brood Clarias batrachus were used in this experiment. Brood fishes were reared up to maturation for spawning operation in the farm by providing artificial diet for 4-5 months before onset of breeding season. In the present experiment, the brood fishes were induced with three growth hormones viz., Ovupin (100 mg dompridone and 0.2 mg S-GnRHa) at the rate of 1 ml.kg-1 body weight, Flash (20 mg S-GnRHa, 10 mg dompridone IP and propylene glycol) at the rate of 1 ml.kg-1 body weight and Human Chorionic Gonadotropin (HCG) hormone at the rate of 2272 IU.kg-1 body weight; respectively. The broods were injected with single injection in all treatments.
Place and Duration of Study: The present study was conducted on induced spawning of Magur (Clarias batrachus) at the Reliance Aqua Farm, Boilor, Trisal of Mymensingh district from March to August, 2016.
Methodology: Sexually mature healthy, uninjured male and female fishes were collected from the broodstock ponds for induced breeding. The fishes were transferred in the clean and germ free conditioning tanks for about 6-7 hours. During conditioning, continuous splash of water was given by keeping the male and female separate. The fishes were then weighed individually and injected intramuscularly with Ovupin, Flash and HCG hormone respectively. Only females were injected at 45° angle of the caudal peduncle. About 23-24 hours of post-injection the testes from males were dissected and mixed with stripping eggs for fertilization.
Results: The incubation period for fertilized eggs were 23-24 hours for all the treatments. Fertilization rates were 78.20±0.52, 93.09±0.61 and 81.60±0.97 % and hatching rates were 54.93±0.61, 75.77±0.47 and 64.41±0.71 % in Ovupin, Flash and HCG treatments, respectively.
Conclusion: This study revealed higher fertilization (93.09 %) and hatching (75.77 %) rate was achieved with Flash hormone. Therefore, Flash hormone could be effective for the artificial breeding and seed production of Magur (Clarias batrachus)
Influence of Stocking Density on Growth Performance of Labeo bata in Cage at River Padma, Rajshahi, Bangladesh
No full textAs a result of climate change, aquaculturists are seeking adaptive culture techniques for sustainable aquaculture. In this case, cage culture is a suitable technique that can mitigate the challenge of climate change, but due to the lack of knowledge of proper stocking density, often productions are not satisfactory. Therefore, the experiment was conducted to evaluate the influence of stocking density on growth and production of an endangered minor carp bata (Labeo bata) in cages for a period of 120 days in Padma River, Rajshahi, Bangladesh. On an average initial weight of bata fingerling of 5 g was stoked in cages under three treatments each with containing three replications using three different stocking densities (106, 71 and 35 fingerling/m3 for T1, T2 and T3, respectively). Supplementary feed (3% per body weight) was given to the cultured species twice in a day. The mean values of water temperature, transparency, pH and dissolved oxygen were in suitable range throughout the experimental period. Significantly (p<0.05) highest mean gross weight (85.82±0.70 g), specific growth rate (2.37± 0.02%), survival rate (83± 3.00%) and food conversion ratio (2.27± 0.03) was found in T3 rather than T2 and T1. The net production in terms of biomass (18.23±2.43 kg/cage) was significantly (p<0.05) higher in T2.The study suggests that, treatment T2 (71 fingerling /m3) as the optimum stocking density to produce maximum production by cage culture of Labeo bata
Sustainable Semi-Intensive Aquaculture of Climbing Perch (Anabas testudineus) in Mymensingh Region, Bangladesh: A Comparative Study
No full textThis study examines the growth and yield of Vietnamese koi with Thai koi for developing a suitable culture management technique of koi for sustainable production and unveiling the most cost effective culture of koi species. The study was conducted for a rearing period of 100 days in four farms at Gauripur upazila in Mymensingh district in Bangladesh. The treatment 1 (T1), treatment 2 (T2) are considered for Vietnamese koi and treatment 3 (T3), treatment 4 (T4) are considered for Thai koi with stocking density 1,72,900 per hectare for T1 and T3 and 2,47,000 for T2 and T4 at four different farms of study area. The ponds were stocked with an initial length of 0.75±0.01 cm and weight of 0.20 g in all the treatments. The culture period has the optimum level of physicochemical parameters. The study reveals that the maximum weight gain was in treatment T1 of Vietnamese koi and lowest in treatment T4 of Thai koi. Similarly, physical length, weight and survival of Anabas testudineus also followed the same trends as weight gain. Individually treatment T1 shows significantly higher specific growth rate than the other treatments. Besides, food conversion ratio was significantly higher in treatment T1 followed by treatment T2, T3 and T4. However, the mean fish production were 17092, 15000, 10746 and 10469 kg/ha in treatment T1, T2, T3 and T4 respectively. Consistently, highest growth, survival and higher net economic benefit from A. testudineus were found in treatment T1 among the four treatments. Vietnamese koi population of treatment T1 has appeared to be most suitable for good quality aquaculture practice for 100 days rearing semi-intensive system among the four treatments. Therefore, monoculture practice of Vietnamese koi is a perfect scheme of choice for a commercially viable and sustainable koi culture to meet up the protein deficit and as well as to accelerate the sustainable development of Bangladesh

No full textThree decapod crustaceans (Penaeus notalis, Procambarus clarkii and Callinectes pallidus) were selected in this study due to their low cost and wide distribution across tropical and temperate regions of the world. The proximate, fatty acids, amino acids and total cholesterol contents of Penaeus notalis, Procambarus clarkii and Callinectes pallidus from Badagry Creek, Lagos, Nigeria were evaluated for their nutritional importance in diet and to human health especially as the demand for these resources is increasing worldwide due to increase in human population, low cost and nutritional benefits. The proximate composition of the selected crustaceans was determined using standard methods of analysis, the cholesterol content was determined using enzymatic kit method, the fatty acid composition was analysed using Gas Chromatography- Mass Spectrophotometer and the amino acid composition was analysed using Amino Acid Analyzer. The proximate composition (moisture, crude fat, crude fibre, crude protein, ash and carbohydrate contents) analysed showed significant difference (p<0.05) among the three selected crustaceans studied, so also the cholesterol content. All the fatty acids in the results obtained except (Palmitic acid (C16:0), magaric acid (C17:0), myristoleic acid (C14:1), (C18:1n-9t), (C22:1n-9), cetoleic acid (C22:1n11c), C18:2n-6t, rumenic acid (C18:2n-7), γ-Linolenic acid (GLA) (C18:3n-6), eicosatrienoic acid (ETE) (C20:3n-3), docosadienoic acid (C22:2n-6) and docosapentaenoic acid (DPA) (C22:5n-3)) showed significant difference (p<0.05). All the essential amino acids indicated significant difference (p<0.05). Moreover, all the non-essential amino acids except cystine were also significantly difference (p<0.05) among the three selected crustaceans. This study revealed that all the selected decapod crustaceans studied are good source of high quality protein, essential amino acids, low cholesterol levels, omega 3 and 6 polyunsaturated fatty acids thereby making them of high nutritional benefits to consumers
