The hatcheries mainly produced carp fish seeds, including five native fish species such as Rui (Labeo rohita), Catla (Catla catla), Mrigal (Cirrhinus mrigala), Bata (Labeo bata), Punti (Puntius sarana) and four exotic fish species namely Silver carp (Hypophthalmichthys molitrix), Bighead carp (Aristichthys nobilis), Grass carp (Ctenopharyngodon idella) and Common carp (Cyprinus carpio). Exotic carps were the highest produced fish seeds (38%) in the Kurigram district, followed by major carps (35%), Bata (16%), Punti (6%) and others (5%). Three main types of inducing agents including PG (pituitary gland), HCG (human chorionic gonadotropin) and Ovupin (GnRHa injection) were used for induced spawning. The rate of 1st dose of injection of PG, HCG, and GnRHa varied from 0.5 to 2 mg/kg body weight, 100 to 200 IU/kg body weight, and GnRHa (only one dose) 0.2 to 0.4 ml/kg body weight, respectively. The rate of 2nd dose of injection of PG varied from 2 to 12 mg/kg body weight. The PG is usually primarily used for first and second doses; the ovulation period of different fish species varied between 12 to 72 hours, whereas the hatching rate ranged from 70% to 95%. Due to the variations in inducing agents and doses, different ovulation, fertilization, and hatching rates were observed.","PeriodicalId":168203,"journal":{"name":"Asian Journal of Fisheries and Aquatic Research","volume":"64 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139211487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seven diets were formulated containing 45% crude protein: control diet was formulated using fishmeal as the principal protein source, three individual diets were prepared using 17% each of fish meal and defatted African palm weevil larvae supplemented with Telfairia occidentalis, Corchorus olitorious and Cymbopogon citratus as phyto-additives. Another three individual diets were prepared using 17% each of fish meal and defatted African palm weevil larvae supplemented with a mixture of Telfaria occidentalis and Corchorus olitorious, Telfairia occidentalis and Cymbopogon citratus, and Corchorus olitorious and Cymbopogon citratus as phyto-additives making it a total of seven diets.

At the end of the feeding trial, the mean weight gain was significantly different (P>0.05) across the fish fed experimental diets. The fish fed with African palm weevil and Telfairia occidentalis as phyto-additives recorded the highest mean weight gain(95.66±25.64) percentage weight gain(91.77±2.14) compared to the other groups. The nutrient utilization indices such as feed conversion ratio, feed efficiency ratio were found to be better in fish fed African palm weevil compared with the CONTROL group. A significantly higher whole-body protein was recorded in fish fed African palm weevil and phyto-additives.

Finding the sex ratio, sexual maturity, LWR, reproductive biology, fecundity, and histological examination of gonads of C. punctata were the main objectives of the present study. The correlation between length and weight was determined by analyzing the power function. Both sexes showed positive allometric growth and the correlation between length and weight was TW= 0.011TL3.09 for males and TW= 0.009TL3.11 for females. The mean condition factor for males was 1.09 (0.89 to 1.24), whereas the mean condition factor for females was 1.12 (0.95 to 1.25). In both cases, the condition factor was more than 1, indicating that the physical condition of both sexes was excellent. Among the 329 samples, 142 (43.16%) were male and 187 (56.84%) were female (male: female = 1: 1.32). The chi-square test showed a significant departure from the 1:1 ratio between the number of males and females within the sample months (df = 1, χ2= 0.01, p=0.05). When they reached first sexual maturity (L50), both sexes were of similar size, as evidenced by their lengths of 14.95 cm. The peak spawning season for both sexes was observed in June and July; however spawning season lasted from April to July.

Fish samples were conducted monthly from May to August 2023, and muscle tissues were analyzed for potential health risks posed by elevated levels of hazardous metals. Heavy metal concentrations of As, Fe, Zn, Pb, and Cd were analyzed using atomic absorption spectrophotometry (AAS). Cd was found in the EDIs of heavy metals in P. elongatus from three stations for adults and children, with minimal variation between stations. For adults, there were no significant discrepancies, but for children, there were substantial differences, especially at Stations 2 and 3. The EDI value for Zn varies significantly across all stations, with the highest value being recorded at Station 3. Fe showed notable differences between stations, while Cu and As had consistent EDI values. The study reveals potential health risks for both adults and children due to heavy metals, with Cd, Pb, and Zn exposure exceeding safe thresholds for both adults and children, while Pb and As have values below safe thresholds, indicating negligible cancer risk. The study calls for further evaluations and mitigation strategies, emphasizing the importance of sustainable practices and acceptable exposure limits, particularly at Stations 2 and 3, to protect vulnerable populations. HI values surpass 1 for both age groups, indicating potential health risks from trace elements in P. elongatus, particularly for Cadmium.

Establishing the Ministry of Fisheries and Marine Resources (MPRH) in 1999 marked a crucial milestone for the industry. Despite challenges in data collection, Algerian aquaculture production reached only 4,779.29 tonnes in 2021, showing a mere 0.2% of African production and 0.0044% of world aquaculture production. More than half of production comes from marine fish cultured in private-sector sea cages. However, shrimp production is almost null. The taxonomic composition of Algerian aquaculture is diverse, with marine and freshwater fish species playing prominent roles. Despite these challenges, the aquaculture field in Algeria has demonstrated an impressive annual growth rate of 12.49% and receives continuous government support. Nevertheless, limited infrastructure, a shortage of expertise, and the need for further research pose significant obstacles. Efforts are underway to integrate aquaculture with agriculture in Saharan zones, further facilitated by governmental support. Overcoming challenges and promoting sustainability through strengthening research capacities, fostering collaboration, and providing financial support is crucial for the advancement of industry. By addressing challenges and embracing sustainability, the aquaculture sector in Algeria can unlock its full potential, ensuring food security, economic growth, and environmental sustainability.","PeriodicalId":168203,"journal":{"name":"Asian Journal of Fisheries and Aquatic Research","volume":"58 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139251069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
