Aquaculture International, 2010
A 45-day feeding trial was carried out to evaluate the use of shrimp protein hydrolysate (SPH) in diets for Oreochromis niloticus, L. SPH was included in isonitrogenous diets replacing fish meal protein by 0, 5, 10, and 20% and offered to Nile tilapia juveniles (1.7 ± 0.4 g) stocked in 40-L glass aquaria. The inclusion of SPH produced no significant differences (P ≥ 0.05) in

The purpose of this study was to evaluate the nutritional adequacy and suitability of rice polish and mustard oil cake as protein sources in the diet of Nile Tilapia (Oreochromis niloticus). To assess the growth performance and feed utilization of Nile Tilapia, three diets containing rice polish (0, 8, and 16%) and mustard oil cake (8, 16, and 24%) were formulated and fed to the fish over a period of 60 days. According to the findings, the growth performance tended to decline as the levels of rice polish and mustard oil cake increased. The control diet (30% Fish meal) resulted in the highest weight gain (373.79±49.78%), whereas the diet (20% Fish meal) resulted in the least weight gain (341.24±27.23%). The specific growth rate (SGR) followed the same pattern, and there were no statistically significant differences in SGR between diets (p>0.05). At the end of this trial, the feed intake (FI) of the various diets ranged between 32.37 g and 37.78 g per fish. Although feed conversion ratio (FCR) and protein efficiency ratio (PER) were not significantly different among diets (p>0.05), feed intake decreased as the incorporation of rice polish increased.
. Effect of shrimp head silage hydrolysate and distiller's dried corn grain on digestibility and growth of red tilapia (Oreochromis mossambicus). Animal Nutrition and Feed Technology, We studied the effect of shrimp head silage protein hydrolysate (SHSP) and distillers dried corn grain (DDCG) as ingredients on the digestibility of diets for Oreochromis mossambicus. Three diets containing 30% protein, 10% lipid, and 4.9 kcal/g calorific value were prepared: a reference diet and two based on the inclusion of 84.0% of the reference diet, 15% of SHSP or DDCG, and 1% of chromic acid as a marker. Six fish (45.5±2.5g) were introduced in each culture unit (60 L). There were significant differences (P<0.05) for the apparent dry matter digestibility among the diets. The SHSP diet obtained the higher dry matter digestibility (86.33±0.8%). While, no differences (P<0.05) in the apparent protein digestibility were observed among the diets and ingredients. The mean final weight (58.77±3.8g) was similar for the three experimental treatments. It can be conclude concluded that the red tilapia is able to efficiently consume diets containing these animal and plant-derived ingredients.
Tilapia culture is widely practiced in tropical and subtropical regions with an annual growth rate of 12% thanks to their high growth rate, disease resistance, and low trophic feeding levels. The increase of aquaculture production has doubled the demand for fishmeal, which has been the most preferred protein ingredient for decades. The provisions of fishmeal are not adequate to sustain the current growth rate of aquaculture industry. Studies have demonstrated possibilities of substituting fishmeal with alternative sources without affecting fish performance. This paper argues the possibility of complete replacement of fishmeal with the alternative dietary protein sources such as terrestrial animal by-products, oilseed plants, single cell proteins and plant protein rich derivatives. The nutritive values of these sources are also discussed. Blood meal and meat and bone meal are perfect fishmeal replacers in tilapia feeds thanks to their high protein and essential amino acid profiles. Soybean meal and cottonseed meal are the best plant protein sources in terms of protein and amino acid contents. Plant proteins could be supplemented with cheap minerals instead of expensive amino acids to produce superior results. The use of aquatic plants and single cell proteins in tilapia feeds should be carefully evaluated because of the varying, and sometimes conflicting results. Both biological and economic evaluations of fishmeal replacers should be studied. More long-term evaluations should be conducted in practical culture systems rather than laboratories. In conclusion, tilapia producers should consider the unconventional dietary sources because complete replacement of fishmeal in tilapia diets is scientifically possible.
The nutritional suitability and cost effectiveness of rice polish and mustard oil cake as protein sources in the diet of Nile tilapia (Oreochromis niloticus) were studied. This study introduced rice polish as a plant protein source for Nile tilapia and three diets were formulated using rice polish (0, 10 and 20%) and mustard oil cake (10.0, 17.6 and 22.0%) for a feeding trail of eight weeks to observe the growth performance and feed utilization. The result was indicated that growth performance tended to decrease with increase in inclusion level of rice polish and mustard oil cake. The control diet (FM35) recorded the highest body weight gain (BWG) (363.79±59.32%) and the least (330.24±32.32%) was in diet FM25. Specific growth rate (SGR) was followed the same trend and no significant differences of SGR was observed among the diets (P>0.05). Feed intake (FI) of different diets was ranged between 30.33 g and 35.08 g per fish at the end of this experiment. Feed intake was also declined with the increase in inclusion level of rice polish, though the feed conversion ratio (FCR) and protein efficiency ratio (PER) were not significantly different (P>0.05) among the diets. The results of this study revealed that partial replacement of fish meal by rice polish and mustard oil cake would be cost effective without any significant change in growth performance.
Growth Response of Nile Tilapia (Oreochromis niloticus) Fries Fed on Silage-based Diets
2021
Fish silage was prepared by minced fish body leftovers by adding formic acid and formulated with other plant sources. The silaging process was completed after 48 days and incorporated into the experimental diets. The growth trial was conducted to investigate the effect of silage incorporation in the diets of Nile tilapia (Oreochromis niloticus L.) fries. Three dried diets containing (T 1) 0, (T 2) 20, (T 3) 30 were prepared with 30% crude protein and the experiment was conducted in 12 glass aquaria with a stocking density of 30 fish/aquarium for 16 weeks. Results indicated that Non-significant differences in WG, FCR, and SGR of O. niloticus were observed between T 2 and T 3 diets. The least growth performance was recorded in T 1 and it was significantly different (P < 0.05) with T 2 and T 3. The fries fed on silage incorporation were the best survival rate (100%) but the fries that fed without silage had less survival rate (83.3%). This indicates fish silage was the best feed for O. niloticus growth and survival rate at an early stage. Under the present study condition, incorporation of fish silage at 20% inclusion in the diets of O. niloticus fries is better and further study is necessary for different inclusions.

The present study aimed to assess the appropriate level of replacement of fish meal (FM) with alternative plant sources in the feed fed to Oreochromis niloticus to evaluate the growth performance. Three isoproteinious (40% crude protein) diets were prepared from different ingredients viz., fish meal, corn gluten meal, wheat gluten meal, and bagasse kenna meal. O. niloticus showed a maximum increase in weight as 9.70, 11.09, 8.53 and 8.32 g during the 2nd, 2nd, 3rd and 2nd fortnight with feeding treatment A, B, C and D, respectively. The growth performance of the fish in terms of weight gain, specific growth rate, feed conversion ratio and protein efficiency ratio were found to be significantly (P < 0.05) higher in the fish fed with 20% replacement of fishmeal in diet B. The worst growth performance was observed in fish fed with commercial diet, designated as diet D. It was concluded that the fish meal can be replaced up to 20 percent with other plant protein sources without any n...

A plant protein mixture (PPM) was tested to replace ¢sh meal (FM) in diets for juvenile Nile tilapia, Oreochromis niloticus. Fish averaging (7SD) 3.770.14 g were divided into 15 groups. Three groups were fed each of ¢ve isonitrogenous (33.6%) and isocaloric (4.7 kcal g À 1 ) diets replacing 0%, 25%, 50%, 75% and 100% of the FM protein with similar percentages of PPM (PPM0, PPM25, PPM50, PPM75 or PPM100 respectively). The PPM consisted of 25% soybean meal, 25% cottonseed meal, 25% sun£ower meal and 25% linseed meal, and 0.5% of both methionine and lysine were added to each diet except for the control. After 16 weeks of feeding, the ¢sh fed diets PPM75 and PPM100 exhibited growth performance not di¡ering signi¢cantly from the ¢sh fed control diet. PPM substitution of up to 75% of the FM protein did not result in di¡erences in the apparent protein digestibility compared with the control, whereas in the PPM100 group digestibility was signi¢cantly lower than in the other groups, except for ¢sh fed the PPM75 diet. The incorporation of PPM in diets did not signi¢cantly a¡ect whole-body dry matter, protein, fat or energy compared with the control. The cost^bene¢t analyses of the test diets indicated that the PPM diets were economically superior to FM. The protein from PPM can completely replace the FM protein in the diets for Nile tilapia, based on the results of this study.

Fish feed is critical in aquaculture production, accounting for over 60% of operational costs, with protein being the most expensive component. Traditionally, fish meal (FM) has been the primary protein source. However, due to declining capture fisheries and high demand, FM has become scarce and costly, necessitating the search for alternative, low-cost, and nutritionally balanced protein sources. A 180-day feeding experiment was conducted to evaluate the effects of replacing FM with a combination of cottonseed and sunflower meal (SFM) in Nile tilapia diets on growth performance, protein digestibility, and economic returns. Freshwater shrimp meal was replaced at 25%, 50%, 75%, and 100% (diets D1, D2, D3, and D4) and compared to the control diet (D0) containing only FM. Monosex Nile tilapia fingerlings (25 AE 0.01 g) were allocated to 15 cages within an 800 m 2 earthen pond. Fish on diets D0 and D1 showed superior growth performance metrics, including final mean body weight, weight gain, daily weight gain, specific growth rate, feed conversion ratio, and survival rate (p>0:05), compared to diets D2, D3, and D4. Growth performance declined significantly with increasing levels of the plant protein mixture (p<0:05). Diet D0 had the highest apparent protein digestibility, while D4 had the lowest. Cost-benefit analysis revealed that diet D0 had the highest production cost, followed by diets D1, D2, D3, and D4, with no significant cost difference between D0 and D1 (p>0:05). Thus, the plant protein mixture can effectively replace FM at a 25% inclusion level in Nile tilapia diets.
T he potential value offish silage as a protein source for freshwater fish was assessed by chemical analysis and by incorporation of silage in exprimental diets for Oreochromis niloticus , Fish silage was prepared from a mixture of Nile tiiapia unedible parts,. Sulphuric formic silage was prepared by addition of 1.5% concentrated sulphuric acid and 1.5% concentrated formic acid to the minced mixture of whole Nile tiiapia bodies. The silage was stored for 24 weeks. The chemical composition of fish silage was determined and some of the changes occuring in protein during storage were described. Three diets were formulated in which fish meal was replaced by fish silages (50,75 andl00% silage), Diets were fed to experimental groups of tiiapia for 13 weeks. A significant difference in growth performance and protein productive value were noted between tiiapia fed on 100% fish silage and other treatements; however feed convertion ratio and protein efficiency ratio showed no significant differences between all treatments. The carcass composition parameters were affected by silage in diets. Cost benefit analysis showed that low profit index and high inclusive cost were obtained by the control diet.
