Life Cycle Assessment of Nile Tilapia (Oreochromis niloticus) Farming in Kenyir Lake, Terengganu

This study presents results from a life cycle assessment (LCA) conducted following the CML-IA method on caged aquaculture of Nile tilapia (Oreochromis niloticus) species at Como River, Kenyir Lake, Terengganu, Malaysia. In this study, the greenhouse gas (GHG) estimation, calculated based on the Intergovernmental Panel on Climate Change (IPCC) 2006 Guidelines, showed that 245.27 C eq (1.69 Kg) of nitrate oxide (N2O) was emitted from the lake. The determination of LCA was conducted using several inputs, namely N2O, compositions of fish feed, materials used to build fish cages (infrastructure), main materials used during operation and several databases, namely Agri-footprint, Ecoinvent 3, European Reference Life-Cycle Database (ELCD), and Industry Data 2.0. The results show that feed formulation is the major contributor to potential environmental impact in aquaculture farming, at 55%, followed by infrastructure at 33% and operation at 12%. The feed formulation consisting of 53% broken rice contributed to marine ecotoxicity (MET), while those consisting of 44% fish meal and 33% soybean meal contributed to abiotic depletion (ABD) and global warming (GW), respectively. It is recommended that the percentage of ingredients used in feed formulation in fish farming are further studied to reduce its impacts to the environment.

This present study was conducted to determine fry production in different male-female sex ratios of Oreochromis niloticusbroodstock in order to improve fry production, which handicapped the development of fish farming in northern Senegal. A total of 180 broodfish (47 males and 133 females) were stocked at a density of 2 fish /m2and was replicated three times for each sex ratio of 1:2, 1:3and 1:4 (male : female). Mean body weight ranges from 136.47Â±2.13 and 107.27Â±2.14 g for female and male O. niloticusbroodstock, respectively. The experiment was conducted for 90 days and the broods were fed on commercial diet containing 32% crude protein.Fish were held in 9 rectangular tanks of 30 m3 each (10 Ã— 3 Ã— 1) and half-filled. The results showed that number of fry produced at different sex ratios were significantly different, with sex ratio of 1:2 producing a highest number of fry (279.67) per female, followed by the 1:3and 1:4 treatment recorded the lowest.Broodstock sex ratios also did not affect female survival rates and all treatments had 100% survival rates. Temperature, dissolved oxygen and pH values obtained were suitable for good water quality and normal tilapia reproduction.In conclusion, the results of the present study recommend to stock Oreochromis niloticus brooders when stocked at a density of 2 fish /m2 at a sex ratio of 1 male : 2 female in order to obtain the highest fry production.

Nile Tilapia Oreochromis Niloticus

Background and Aim: Industrial waste, such as heavy metals, is a major source of water pollution; at high levels, such pollution can reduce river water quality to the extent that it becomes unsuitable for aquaculture of freshwater fish. This study aimed to focus on the effects of copper (Cu) exposure in Nile tilapia (Oreochromis niloticus) and specifically the ability of Lactobacillus-based probiotics supplementation in fish feed to ameliorate damage to gonads and negative effects on red blood cells (RBCs), whole blood cells (WBCs), hematocrit (HCT) levels, hemoglobin (HGB) levels, and malondialdehyde (MDA) levels following such exposure. Materials and Methods: Thirty-two Nile tilapia fish were divided into eight groups: A negative control (without probiotics or Cu), a positive control (with probiotics but without Cu), three treatments with probiotics in feed, and one of three Cu concentrations (0.75, 1.50, or 3.00 mg/L), and three treatments with these three Cu concentrations but without probiotics in feed. The probiotics concentration in feed was 25 mL/kg (1×108 CFU/mL). Feeding was for 15 days, after which the hematological parameters, gonadal (testis) structure, and MDA levels of fish were analyzed. Results: Exposure to Cu significantly (p<0.05) affected fish hematology (decreased HGB, HCT, RBC, and WBC levels) and altered the structure of the testes. However, the addition of probiotics to fish feed significantly (p<0.05) ameliorated these effects on hematology and maintained the histological structure of the gonads. Conclusion: Cu exposure at ≥1.5 mg/L affected the hematologic parameters, gonadosomatic index, MDA levels, and testicular cells and tissue of Nile tilapia. However, probiotics supplementation in fish feed helped ameliorate the negative effects of Cu on these parameters. Thus, the Lactobacillus-based probiotics used in this study were apparently able to neutralize Cu toxicity in Nile tilapia.

The purpose of this research was to determine the effect of yeast (Saccharomyces cerevisiae) with different composition of 5%, 10%, 15%, 20%, and without yeast in feed formulation on growth of tilapia (Oreochromis niloticus). The experimental fish used in this study had an average lengths of 2-3 cm and weight of 1.0 g. This research used cage measuring 100 x 100 x 100 cm3 that was placed in outdoor concrete pond of 3.5 x 5 m2. Each cage filled with 10 fishes with three replication. The dose given to the fish was 10% of the weight of biomass. The fish was fed for three weeks, 3 times a day at 08.00 am, 12.00 pm, and 16.00 pm.. Research results showed that the greatest growth was achieved in fish treated 20% yeast and the lowest was observed in control fish (without yeast). Based on statistical analysis, all treatment displayed similar effect on all growth parameters.Keywords: Fish feed, Saccharomyces cerevisiae, yeast, Nile tilapia, fish growth

Leaf Powder

Tilapia (Oreochromis niloticus) has been gaining ground in cultivation and sale in Bangladesh but due to price hike of fish feed the culture of this fish faced many challenges. In the present study, the optimal level of dietary moringa (Moringa oleifera) leaf powder was used as feed supplement to determine the growth performances, some selective blood parameters and bacterial load in Nile tilapia, Oreochromis niloticus. Commercial diet containing moringa leaf powder at 0g/kg, 100g/kg and 200 g/kg diet was used. The diet containing 100g moringa leaf/kg diet resulted in increased weight gain, average daily gain, specific growth rate, condition factor and survival rate. A significant (p<0.05) reduction in RBC and WBC were found as the moringa leaf inclusion increased in the diets but no significant (p<0.05) differences were observed among the three different rearing conditions. In most of the cases, the diet containing 100g moringa leaf powder/kg diet displayed lower amount of bacterial count but no significant improvement was found in bacterial load among the different treatment conditions. The results suggest that dietary moringa leaf powder could be included in the diet of Nile tilapia at possibly not over 100 g/kg diet for the betterment of growth, survival, immune response and microbial challenge.

Motile Aeromonas Septicaemia

This study aims to apply vaccination against bacterial disease. The purpose of vaccination is to trigger the immune respone both non-specific and specific of fish against bacteria Motile Aeromonas Septicaemia (MAS) caused by Aeromonas hydrophila. The vaccination for fish with different ages: 2-3 weeks and 5 weeks were done using immersion method. The fish were re-vaccinated (booster) after two weeks of the first vaccination. The survival rate was < 50 % for juveniles 2-3 weeks and > 50% for juveniles 5 weeks. Survival rate for juveniles 5 weeks was higher than juveniles of 2-3 weeks. This shows that organs of juveniles of 5 weeks were more complete than the 2-3 weeks juveniles. The age of fish is one of the important factors for successfully vaccination. Penelitian ini bertujuan untuk melakukan penerapan vaksinasi terhadap penyakit bakterial. Vaksinasi ditujukan untuk merangsang respon kekebalan non- spesifik dan spesifik pada tubuh ikan terhadap penyakit Motile Aeromonas Septicaemia (MAS) yang disebabkan oleh bakteri Aeromonas hydrophila. Vaksin diberikan pada benih ikan nila yang berbeda umur yaitu 2-3 minggu dan 5 minggu dengan menggunakan metode perendaman. Ikan divaksinasi ulang (booster) setelah 2 (dua) minggu dari vaksinasi yang pertama. Prosentase kelangsungan hidup < 50 % untuk benih umur 2-3 minggu dan > 50% untuk benih umur 5 minggu. Jumlah kematian benih umur 2-3 minggu lebih tinggi dari 5 minggu. Hal ini menunjukkan bahwa fungsi organ benih umur 5 minggu telah lebih lengkap dari pada benih umur 2-3 minggu. Umur ikan merupakan salah satu faktor penting penentu keberhasilan suatu kegiatan vaksinasi.
