  A 12-weeks feeding trial was conducted to investigate the effects of commercial cellulase enzyme products on the nutritive value of Canola Meal (CM) determined in angel fish fries. Nine isocaloric and isoprotein experimental diets (44% protein and 3500 kcal kg-1) were prepared by adding cellulase enzyme (0.50 and 1.00 g kg-1) at two different levels to feed including 7.20 and 35.99% canola meal instead of fish meal at basal diet. All diets were fed ad libitum. Weight gain, feed conversion ratio, body composition and nutrient digestibility were measured. High canola+enzyme diet gave significantly lower growth rates (1.51±0.02 g) (p<0.05). The low canola diet also resulted in higher weight gain but adding of cellulase enzymes in different ratios to diets showed no effect in growth parameter and nutrient digestibility.

  Tilapias are one of the most important domesticated fish today. Production widely distributed around the world. Lecithin also known as Phosphatidyicholine (PC), is a special type of lipid (a phospholipid) found naturally in the body. Research has shown that crustaceans and fish cannot adequately synthesise the phospholipids they require for maximum performance. Therefore, phospholipids must be added to their diet. Therefore, the experiment was designed to evaluate the effects of soybean lecithin on the growth and performance of feed conversion in Tilapia fry. The experimental period was planned as a 3 months period. Twenty one aquariums (7 groups-3 replicates) were used and 25 fish were stocked at the rate of 200 fish m-3 in each aquarium, by a completely randomized design. The effects of supplementary feeding of the tilapia (Oreochromis niloticus) fry with feeds enriched with soybean lecithin were evaluated by adding soybean lecithin to the basal diet at the rate of 1-5%. The fish were fed for 90 days to check the growth, protein efficiency ratio, feed conversion ratio, body composition and survival ratio. At the end of experiment, the best live weight increase was found to be 3% protein efficiency ratio and the feed conversion ratio was found to be 1.90 and 1.75, respectively in the 2% lecithin-treated group, supplementing soybean lecithin at the rate of 4 and 5%, which enhanced the fat content of treated fish (p<0.05).

  A 12 week feeding experiment was conducted in an aquarium (80x40x40 cm) to determine the potential use of canola meal as a partial replacement of fish meal in the isonitrogenous (approximately 44% crude protein) diet for angel fish fries with an initial average weight of about 0.91 g. Diets were formulated to include 0, 8, 16, 24, 32 and 40% (CM0, CM8, CM16, CM24, CM32 and CM40, respectively) of fish meal protein as a substitute by canola meal. Growth performance (weight gain, specific growth rate) decreased significantly, when the replacement level of fish meal protein was increased from 24% and higher, the CM40 diet was the lowest in all groups. When the replacement level of fish meal protein 16% (diet CM16) Feed Conversion Ratio (FCR) was the lowest and Protein Efficiency Ratio (PER) was the highest. There were no significant differences in the moisture, lipid, crude protein and ash content in whole body. Fish were fed with pelleted experimental diets to satiation and the feces were collected by siphoning. The apparent digestibility of dry matter ranged from 80.92-88.49%, protein from 91.16-93.71% in the experimental groups. The high level of canola meal in diets was negatively affected in terms of both dry matter and of protein digestibility. These results support the use of canola meal as important replacement protein source for fish meal of angel fish.

  In this study, effects on fatty acid composition of D. magna produced in the different nutritional mediums (S. acuminatus, yeast, S. acuminatus+yeast, fish oil and yeast+fish oil) were investigated. Considerable differences were found in fatty acid composition of D. magna fed with algae, yeast and fish oil. D. magna fed with algae contains considerable amounts of PUFA (46.2%), though this algae is completely bare of EPA acids. D. magna fed with yeast was contained highest of MUFA (53.5%). In contrast to algae, yeast contains mainly 16:1 and 18:1 acids and was devoid of 18:3 or PUFA. D. magna fed with fish oil contained considerable amounts of PUFA especially, EPA and DHA acids. The rate of synthesis of these acids is rather low, although fish oil contains considerable amounts of these fatty acids.
