Abstract We have evaluated the effects of different fish feeds on the body composition, growth, and enzyme activities of Labeo rohita (Rohu). In total, 240 fishes between the average weights of 24.77±2.15g were studied. The treatments were applied in a completely randomized design, with 4 treatments of 60 fishes each. Treatments consisted of four different fish feeds [Oryza (T1), AMG (T2), Aqua (T3), and Supreme (T4)]. Body composition, growth performance, and enzyme activities were evaluated. There was a significant variation in performance of fishes fed with different type of feed; as fishes having Oryza feed showed the highest weight gain, specific growth rate (SGR), and best feed conversion ratio (FCR) as compared to other groups that were considered to be significant (P ≤ 0.05). High net weight gain was obtained in T4 when compared with T2 and T3. FCR value of T4 was less than T1 but higher than T2, T3 and T2, which showed the lowest values. The specific growth rate was recorded as average in T4, but T2 led a high SGR than T3. Similarly, crude protein level and digestive enzymes activity was recorded significantly highest in fed with Oryza (T1) as compared to AMG (T2), Aqua (T3), and Supreme (T4). Water quality parameters were recorded significant in all treatments except pH and DO of treatment (T1), significantly different from other treatments. It was concluded that Rohu (Labeo rohita) could show a promising growth rate and protease enzyme activity when fed with the Oryza feed of 25% protein.

Background: Probiotic is the best solution (Produce antimicrobial compounds, inhibit colonization of pathogenic microorganism, increase digestive ability and confer better health to the host) as an alternative to antibiotics against various microbial infection in freshwater and marine water. The freshwater fish Cyprinus carpio was selected for this research work (due to high growth rate, high protein content, ability to survive under different climatic conditions and its availability throughout the year) to observe the effect of probiotic Enterococcus gallinarum N3 supplemented feed on its growth. Methods: In this present research work Prepared three different concentration of probiotic Enterococcus gallinarum N3 (0.1%. 0.5% and 1.0%) along with basal diet containing other ingredients (fish meal, groundnut oil cake, wheat bran, starch and Vitamin mineral premix). Initially 14 days acclimatized freshwater fish Cyprinus carpio to laboratory condition selected randomly for four treatment groups as Control (C) and probiotic feed treated T1, T2 and T3 group. The experiment was carried out for 42 days with continuous aeration, natural photoperiod of 16 hrs light and 8 hrs dark, maintain temperature constant and fishes fed diet twice daily. The feed ingredients and experimental diets analysed for proximate composition and measured Weight gain, Specific growth rate (SGR), and Feed conversion efficiency (FCE). Result: The proximate composition of the feed was determined as percentage dry matter in which 36.21% protein, 6.8% moisture and 7.8% of lipid. The probiotic feed experiment was conducted for 42 days and entire group of fishes was survived. The effect of probiotic feed on growth performance of Cyprinus carpio was measured as initial weight, final weight, weight gain, specific growth rate and feed conversion efficiency. The growth changes were observed before and after treatment with 0.1%, 0.5% and 1.0% of probiotic E. gallinarum N3 fed to Cyprinus carpio. The final weight (g) and final length (cm) was measured in treatment T1 (3.107 g; 3.32 cm), T2 (3.258 g; 3.40 cm) and T3 (3.413 g; 3.52 cm) respectively as compared with Control group C (2.255 g; 2.98 cm). The percentage weight gain obtained in group T1 (37.78%), T2 (44.45%) and (51.55%) respectively as compared with Control group C (29.54%). Maximum specific growth rate was observed in treatments T1 (0.94 % day-1), T2 (0.99% day-1) and T3 (1.02% day-1) as compared with control group C (0.56% day-1). The results showed better growth performance and feed utilization in all the three treated groups T1, T2 and T3. The best growth performance (final weight, final length, weight gain, specific growth rate and feed conversion efficiency) and feed utilization (moisture, protein and lipid) was observed best in T3 (1 g kg-1) group of fishes as compared to control C group. There was significant difference (P greater than 0.05) in final weight, final length, weight gain, specific growth rate and feed conversion efficiency.

Growth performance of Hypophthalmichthys molitrix (Silver carp) and Barbodes gonionotus (Sar puti) fingerlings were studied separately in aquaria by feeding cultured microalgae (Chlorella ellipsoidea, Scenedesmus obliquus and Spirulina platensis) in different combinations for a period of 21 days. Fertilizer factory effluent was used to grow these microalgae. Significantly (p<0.05) higher weight gain of H. molitrix (81.16%), was in the treatment T2 (Rearing by feeding 100% S. platensis) and the minimum percentage (- 4.29%) was obtained in the control (fed on fishmeal and mustered oil cake). Specific growth rate (SGR, %/day) of H. molitrix were determined - 0.21 to 2.84 for all the treatments which was significantly (p<0.05) higher in T2. Survival rate of H. molitrix was 25.90 to 77.80%. In the case of B. gonionotus, significantly (p<0.05) higher weight gain (149.10%) was observed in t2 (Rearing by feeding 100% S. platensis). The SGR (%/day) of B. gonionotus were ranged from 2.25 to 4.33 which was significantly (p<0.05) higher in t2 than all other treatment except control. Survival rate of B. gonionotus was ranged from 97.78% to 100%. The reared fingerlings were found nutritionally rich. Key words: Fingerlings; Microalgae; Growth performance; Specific growth rate.

The objective of this work was to evaluate the effect of sustained swimming and dietary protein levels on growth and hematological responses of juvenile pacu (Piaractus mesopotamicus). A completely randomized design was used in a 3x2 factorial arrangement, with three levels of dietary protein (24, 28, and 32% crude protein), two rearing conditions (sustained swimming or motionless water), and 15 replicates. Fish were subjected to sustained swimming at the velocity of two body lengths per second (2 BL s-1), for 45 days. The level of dietary protein and the swimming conditions affected the performance, growth, and hematological profile of pacu. Swimming conditions influenced nutritional factors, increasing daily weight gain, specific growth rate, number of erythrocytes, mean corpuscular volume, and mean corpuscular hemoglobin. Fish under sustained swimming and fed with 24% crude protein showed better growth performance, with higher specific growth rate (4.11±0.88) and higher daily weight gain (2.19±0.47 g per day). Sustained swimming can increase the productive performance of pacu and simultaneously reduce dietary protein levels.

The use of Silkworm (Anaphe infracta) pupae as a protein source was investigated for its ability to replace fishmeal in the diet of Clarias gariepinus, African cat fish. Five dried diets formulated at 40% crude protein were fed to fingerlings of an average initial weight of 14.33g at 0 (control diet), 25, 50, 75 and 100% inclusion levels of silk worm meal. The experiment was conducted for 84 days were measured. Mean weight gain (MWG), specific growth rate (SGR), feed conversion ratio (FCR). The five inclusion levels of silk worm pupae supported the growth of Clarias gariepinus fingerlings, the growth and feed utilization were favoured by high inclusion level of silk worm meal. Significant differences (p<0.05) were observed among the treatments, although there were no significant differences (p>0.05) in the growth parameters between 50% and 75% inclusion levels. The 100% silk worm pupae meal inclusion gave the best final mean weight gain of 10.29g specific growth rate of 0.93%, feed conversion ratio of 2.18 and protein efficiency ratio (PER) of 0.012. The carcass protein and lipid contents increased compared to the levels of both at the beginning of the experiment. Even though, there were no significant differences (p>0.05) among proximate composition of the fish groups fed 25, 50 and 75%. The results showed that diet consists of 100% silk worm meal could be used as a complete replacement for fish meal in the diet formulation for Clarias gariepinus fingerlings.

Significant Difference

Fish meal is generally expended as the foremost protein supply in the fish diet. The rising cost of this component inflicted the aquaculture industry to seek a substitute in lessening the pellet cost. Thus, fish waste was tested in this study to investigate its viability. An experiment was performed to study the effects of fish waste and carcass on the growth performance of Nile tilapia fry. Solid fish waste of three different common species available in Mukah’s wet market was formulated into an artificial diet. The diet was formulated into three treatments consist of three protein levels (40%, 45% and 50%) with 4000 kcal/kg energy. A controlled group was fed with a commercial pellet consisting of 45% protein level. Fish were fed at 4% of body weight twice daily for 45 days. Fry reared in a controlled group was discovered highest weight gain, specific growth rate and length gain. There was no significant difference in all treatments for all parameters measured. The lowest weight gain and specific growth rate were recorded in fish fed 45% protein level (T2) group. Fish in T3 (50%) achieved the highest survival rate while T1 (40%) group recorded the lowest. The best and lowest Feed Conversion ratio (FCR) was recorded in the control group. In conclusion, the performance of formulated feed using fish waste is similar to commercial pellet as no significant difference can be observed in all parameters measured.

Fulfill needs of Siamese gourami still rely on the catch from nature, so the population in nature has become decreased. The increase of Siamese gourami fish production from culture is still constrained by the survival rate and slow growth rate in the seed phase. The purpose of this research was to determine the effect of Siamese gourami stocking density on the application of optimum temperature and salinity to growth performance for optimization of production capacity. Application of optimum temperature and salinity refers to the results of previous research, i.e., temperature of 28 °C and salinity 3 ‰. Siamese gourami seed with length of 2.96 ± 0.42 cm and weight of 5.27 ± 0.10 g used in the research. The experimental design used completely randomized design with four treatments, i.e. 1 fish L-1, 2 fish L-1, 3 fish L-1 and 4 fish L-1. The results showed that there were an effect of different stocking density on absolute growth weight and length, survival rate, specific growth rate and productivity. This is shown in the C treatment which growth was 4.95 ± 0.037 g, length 3.51 ± 0.01 cm, survival rate 93.47%, specific growth rate 1.22% and fish productivity of 625.76 g.

An experiment was designed and carried out to assess the growth performance and feed utilization (weight gain, feed conversion ratio, protein efficiency ratio, specific growth rate, feed intake and survival) of Clarias gariepinus fingerlings fed graded levels of toasted Leucaena leucocephala seed meal based diets with the aim of establishing the best inclusion level of Leucaena seed meal. One hundred and eight (108) fingerlings with an initial mean weight of 2.10g were allotted at random to six treatments in triplicate groups with each treatment tank having six fingerlings and were fed with isocaloric and isonitrogenous diets containing 40% crude protein (CP). The toasted seed meal was used to replace soybean meal in the diets in the following proportions: diets I (0%), diets II (10%), diets III (20%), diets IV (30%), diets V (40%) and diets VI (50%). At the end of the feeding trials that lasted for 6 weeks, the mean weight gains of fish, relative weight gain, specific growth rate, feed intake, feed conversion ratio and protein efficiency was highest in treatment I while mean weight gain of fish, relative weight gain, specific growth rate and feed conversion ratio was lowest in treatment V. Feed intake was lowest in treatment VI and protein efficiency was lowest in treatment II. Survival among treatments slightly varied significantly but was not as a result of the feed consumed. At the end of the experiment, the recommended inclusion level of Leucaena seed meal was 20%.

Thai pangus polyculture with carps has been increasing for its high potential, however very few attempts were made to compare its growth using different types of feed. A research was undertaken to assess the effect of three types of feed on growth of Thai pangus (Pangasius hypophthalmus) and rohu (Labeo rohita) in polyculture system for 11 months from 15 May 2005 to 15 April 2006 in Khulna. Growth performance using Hand-made Feed (F1) was compared with two commercial fish feed, Sunney Feed (F2) and Saudi-Bangla Feed (F3) in three respective treatments of T1, T2 and T3. All treatments were carried out in triplicate at 24700/ha for Thai pangus and 4940/ha for rohu. Average initial weight of Thai pangus and rohu were 4.5 and 33.5g respectively. Growth performance was influenced by feed type. Average final weight of Thai pangus and rohu were 820 and 710; 846 and 770; and 872 and 717g with specific growth rate 1.58 and 0.93; 1.59 and 0.95 and 1.60 and 0.93 % day -1 in T1, T2 and T3 respectively. Feed conversion ratio was estimated 2.3 in T1, 2.1 in T2 and 1.96 in T3. The result showed a typical increasing trend of final weight and specific growth rate of Thai pangus along with the increasing of feed protein level. But rohu showed highest growth in T2 where protein level was 26-30% which was lower than that of T3 (Protein level 28-32%). The study suggests that suitable protein level and quality feed is required for adequate growth of fish.
