Studies were carried out on the growth performance of Tilapia fry, Oreochromis niloticus cultured with zooplankton, Moina macrocopa in comparison to commercial feed. Three types of feed were used in three treatments where treatment-1 was fed with handmade feed (control), treatment-2 with commercial feed and treatment-3 with live zooplankton M. macrocopa. Thirty fry were stocked in each 60 L aquarium for a rearing period of 56 days. The fishes were fed twice a day at 90-400 Moina/individual fish for first 20 days, then 500-850 Moina/individual fish for 15 days and 900-1250 Moina/individual fish for remaining days. Sampling was done at 14 days interval. The growth performance of M. macrocopa was higher in the treatment fed with Spirulina which was 6350 individuals/ L of water and in the treatment fed with yeast it was 5100 individuals/L of water at 12th days. The study showed that condition factor of tilapia fry found in treatment-3 fed with M. macrocopa was comparatively higher (2.18±0.09) than that of treatment-2 fed with commercial feed (1.86±0.13) at a 56-day culture period. Average daily gain was significantly higher in the treatment-3 fed with M. macrocopa (0.13±0.01) than those of treatment-1 (0.06±0.01) and treatment-2 (0.08±0.01). The best value of feed conversion ratio and specific growth rate was found in treatment-3 fed with M. macrocopa than commercial feed and handmade feed. Protein content was significantly higher (15.91%) in treatment-3 than those of treatment-1 (10.96%) and treatment-2 (11.88%). The findings of this study suggest that growth parameters and body composition of Nile Tilapia was better in treatment-3 fed with M. macrocopa.Bangladesh J. Sci. Ind. Res. 52(2), 81-88, 2017

Main Protein

During the tuna canning process, about 52~54% of the total weight of the fish is discarded as waste, which can be processed in order to obtain tuna byproducts meal (TBM), or stabilized as tuna silage hydrolysates (TSH). Both products were tested as replacements of soybean meal (SBM), in diets for fingerling male Nile tilapia Oreochromis niloticus. Seven test diets were isonitrogenous (35% CP) and isoenergetic (19 kJ g-1): a basal diet contained SBM as main protein source (TSH0); four experimental diets had increasing inclusion levels of TSH replacing 25, 50, 75 and 100% of the SBM protein. The sixth diet contained TBM as sole protein source, and a commercial feed for tilapia was used as reference diet (RD). The diets were fed for eight weeks to triplicate tanks, each with 15 fry tilapia (initial weight of 0.89 ± 0.29 g). Tilapia fed the TBM diet had greater weight gain and feed intake, and lower feed conversion ratios than those fed diets containing with TSH. The RD, TSH25 and TSH50 diets gave the similar growth response. Fish fed diets TSH0, TSH75% and TSH100% showed reduced growth performance.

 This study was done to explore the effect of replacing mustard oilcake by linseed oilcake in feed on the growth performance of Nile Tilapia (Oreochromis niloticus). Mustard oilcake (MOC) was replaced by linseed oil cake (LOC) at three different level 0%, 50% and 100% to prepare three different types of diets. Diets were prepared with about 18% analyzed crude protein content. Fingerlings were kept in three happa with three replications for each diet in completely randomized design (CRD). Fish of average weight 5.31 g were stocked in happa having size 1.5m×1.5m×1.2m. The experimental fish were fed 3% of their body weight per day, once in the morning for five months continuously. No significant difference (p>0.05) in final mean weight, final total weight, average daily weight gain (DWG), survival rate, extrapolated gross fish yield (GFY), extrapolated net fish yield (NFY) and apparent feed conversion ratio (AFCR) among different treatments were observed. Hence, linseed oilcake can be used as the substitute in the feed of tilapia, if it is locally available.  Journal of Institute of Science and Technology, 2017, 22 (1): 10-16

A 12-week research was conducted to determine the effects of choline and methionine supplementation on the growth performance of Nile tilapia (Oreochromis niloticus). Three diets, P2-P4 with 0.04; 0.08; 0.12 % of choline; P6-P8 with same levels choline plus methionine (0.15 %); a diet with only 0.15 % methionine (P5); and control without any supplementation (P1) were fed to tilapia (initial weight ±21.05 g) for 12 weeks. Final weight (FW), Body Weight Gain (BWG), Average Daily Gain (ADG), Specific Growth Rate (SGR), and Protein Efficiency Ratio (PER), Feed Efficiency (FE), Feed Intake (FI), Feed Conversion Rate (FCR), Survival Rate (SR), crude protein and lipid of fish fed various levels of choline and methionine were also measured. The results showed that tilapia fed 0.04 % choline (P2) had significantly better growth parameters and feed efficiency than other groups. Meanwhile, SR of tilapia was not affected by any supplementation of choline and methionine. The tilapia fed 0.08% choline (P3) showed the highest crude protein (52.50 ± 0.98 %) in the carcass proximate but low lipid (19.03 ± 0.10 %). This finding demonstrated the benefits of choline (0.04-0.08 %) supplementation in the tilapia diet in term of growth and carcass proximate.

El presente estudio evaluó el uso de las microalgas Arthrospira sp., Chlorella sp., Isochrysis sp. y Nannochloropsis sp. como constituyentes parciales del alimento balanceado para tilapia del Nilo (Oreochromis niloticus) bajo condiciones de cultivo estático en un estudio de 53 días de duración. Un alimento balanceado comercial con contenido de proteína cruda de 45% se utilizó como dieta control, mismo que se molió finamente y se reconstituyó incorporando, a un nivel de inclusión de 25% de la dieta, las harinas de las cuatro especies de microalgas mencionadas. Se analizaron parámetros de producción de tilapia, incluyendo índices de crecimiento y supervivencia, mediante análisis de varianza. Los índices de crecimiento, tales como peso final, peso ganado y porcentaje de peso ganado de los peces alimentados con las microalgas Arthrospira sp. y Chlorella sp., así como la supervivencia, fueron similares a los de aquellos que recibieron la dieta control, mientras que el crecimiento de peces alimentados con las microalgas Isochrysis sp. y Nannochloropsis sp. fue inferior estadísticamente. Estos resultados indican que Arthrospira sp. y Chlorella sp. pueden ser incorporadas a un nivel de 25% del alimento balanceado sin afectar significativamente el crecimiento o la supervivencia de O. niloticus.ABSTRACTIn the present study, the use of the microalgae Arthrospira sp., Chlorella sp., Isochrysis sp., and Nannochloropsis sp., as partial constituents in diets for Nile tilapia (Oreochromis niloticus), was evaluated in static tanks in a 53-day study, with a commercial diet containing 45% crude protein as a control treatment. Then, we replaced 25% of this diet with meals derived from each of the four microalgae species. Analysis of variance was employed to evaluate fish growth performance. Fish fed the diets with the microalgae Arthrospira sp. and Chlorella sp. had growth performance comparable to that of fish fed the control diet, as evaluated by growth parameters, such as final weight, weight gain, and percent weight gain, among others. In contrast, growth of fish receiving the microalgae Isochrysis sp. and Nannochloropsis sp. was significantly lower. Results of the present study indicate that the use of 25% of Arthrospira sp. and Chlorella sp. meals incorporated into the diet of O. niloticus does not compromise fish development, although there seems to be an opportunity for a further increment of the replacement level.

The aim of this study was to evaluate the influence of vitamin and β-glucan supplementations on growth performance of growing-finishing pigs in Ben Tre province. A total of 36 post-weaned piglets (Duroc x Yorkshire-Landrace) with the initial live weight of 17.42 kg±0.26, was allotted into 3 treatments and 4 replications in a completely randomized design. There were three diets, including basal diet (BD) without any addition of β-glucan or vitamin (diet CT), the BD supplemented with vitamin (diet Vit) and the BD supplemented with β-glucan (diet Glu). The results on growth parameters indicated that final live weight (kg), weight gain (kg), and average daily gain (g/head/day) of pigs in the experimental diets were significantly higher (P<0.01) than those in the control treatment. FCR was lowest in Glu and highest in the control (P<0.01). Financial benefit based on feed and veterinary expenses was higher in the vitamin and β-glucan supplement diets than that of the control from 15.74% to 18.98%, respectively.

This work evaluates the growth and body development of Oreochromis niloticus in floating cages in the Toho Lake of Benin. Thus, 6000 juvenile monosex male with an average initial weight of 8.87 ± 4.89 g and average initial total length of 7.87 ± 1.43 cm were randomly distributed in two floating cages (5 x 5 x 2.5 m3) at the stocking density of 3000 fish/cage. The fish were hand-fed to apparent satiation, three times daily, using 45-32% crude protein commercial pelleted floating feed Skretting®. The physico-chemical parameters of lake water recorded every 72 hours during the experiment were within the suitable ranges for fish culture and were as follows: temperature (27.78 ± 0.41 °C), pH (7.55 ± 0.22), dissolved oxygen (4.03 ± 0.96 mg/l), ammonium (0.31 ± 0.18 mg/l), nitrite (0.29 ± 0.07 mg/l) and nitrate (0.27 ± 0.12 mg/l). The variables studied at the end of  the 215 days of rearing were as follows: final mean total length (26.61 ± 2.99 cm), final mean standard length (22.40 ± 2.74 cm), final mean predorsal length (6.93 ± 0.94 cm), final mean head length (3.45 ± 0.58 cm), final mean dorsal fin base length (13.55 ± 2.96 cm), final mean inter-orbital width (2.97 ± 0.37 cm), final mean body height (8.57 ± 1.56 cm) and final mean caudal peduncle height (3.27 ± 0.39 cm). The zootechnical growth parameters evaluated were as follows: survival rate (91.5%), final mean body weight (402.18 ± 137.05 g), average daily weight gain (1.83 ± 0.08 g), specific growth rate (0.77 ± 0.03%/day), feed conversion ratio (1.74 ± 0.09%) and protein efficiency ratio (1.62 ± 0.06). These results compared to the literature indicate interesting growth and body development and it would be important to promote in-cage farming of Oreochromis niloticus.
