 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

The effect of different phytoplankton species on growth, survival and fatty acids composition of Nile tilapia (Oreochromis niloticus) was evaluated for 24 weeks. Treatment-1 was fed with commercial feed as Control, treatment-2 was fed with Spirulina platensis, treatment-3 was fed with Chlorella vulgaris and treatment-4 was fed with mixed phytoplankton (Chlorella vulgaris, Spirulina platensis, Azolla pinnata and Pistia stratiotes). The condition factor of fish found in treatment-3 with Chlorella vulgaris (1.73 ± 0.02) was significantly higher than that of treatment-1 as control (1.56 ± 0.02) at 24 weeks culture period. The specific growth rate of treatment-4 with mixed phytoplankton diet (2.00 ± 0.10) was significantly higher than treatment-3 with Chlorella vulgaris (1.13 ± 0.05) after 24 weeks of rearing. There was no significant difference among the four treatments in case of average daily gain, feed conversion ration and survival rate. The use of different phytoplankton such as Spirulina platensis, Chlorella vulgaris and Azolla pinnata influence the fatty acid profiles of Nile tilapia. Findings also showed that the amount of eicosapentaenoic acid (EPA) in treatment-3 fed with Chlorella vulgaris (1.83 ± 0.22) was highly significant than the other treatments. The highest amount of docosahexaenoic acid (DHA) was found in treatment-1 fed with commercial feed (2.70 ± 0.53%) and lowest in treatment-2 with Spirulina platensis (0.06 ± 0.02%). Among 19 unsaturated fatty acid, the highest concentration of PUFAs were recorded in treatment-3 (42.55 ± 3.46%) fed with Chlorella vulgaris. The findings of this study suggest that raising Nile tilapia with Chlorella vulgaris and Spirulina platensis in ponds may improve the growth and fatty acid profile of the fish. Dhaka Univ. J. Biol.
