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.

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.

Abstract Lobster is among freshwater crustaceans which is potentially cultivated in aquaculture system. This present study was conducted to determine the growth and survival rate of freshwater lobster Cherax quadricarinatus fed different forage feed. The experimental methode used a completely randomized design consisted of 4 treatments in triplicate: commercial diet (PL), commercial diet and carrots (PW), commercial diet and potatoes (PK) and commercial diet and sweet potatoes (PU). The experimental lobsters were 5-7 cm in size and 6-8 g in weight. Results indicated that forage feeding can affect the total weight and length, weight gain, specific growth rate and survival rate of lobster. Data showed the best weight gain and specific growth rate were found in PW (34.37±0.30%) and (1.05±0.03%), respectively. The lowest survival rate was seen in PU at 86.67%. However, the best feed conversion ratio gained by PL at 1.74±0.09. This study suggested that the combination of commercial diet with carrots provided the best growth performances in freshwater lobster Cherax quadricarinatus.

Pakan apung komersial dengan kadar protein 40% diberikan sebesar 6% per biomassa yang diberikan dua kali sehari. Parameter yang diamati yaitu pertumbuhan bobot mutlak, sintasan, laju pertumbuhan spesifik (SGR), dan biomassa. Hasil percobaan menunjukkan bahwa perlakuan padat tebar 50 ekor/m3 menghasilkan pertumbuhan terbaik dengan bobot akhir 15,89 ± 1,43 g; pertambahan mutlak 10,48 ± 1,41 g; sintasan 94,67 ± 4,6%; dan SGR 0,75 ± 0,04%. Dari hasil penelitian ini, padat tebar 50 ekor/m3 merupakan kondisi yang terbaik untuk pemeliharaan benih ikan semah di KJA. Hasil penelitian ini dapat dijadikan informasi awal tentang potensi budidaya ikan semah dengan sistem budidaya KJA perlu dikembangkan di masa yang akan datang.Semah mahseer (Tor douronensis) is a species from the genus Tor and highly valued in local and national markets. Nevertheless, the fish production from net cage is currently limited. In order to increase its productivity, research on the growth of semah mahseer fingerlings reared in floating net cage systems needs to be carried out as this species is predominantly cultured in the clean water ponds. This study was conducted to obtain information on the growth performance of the first generation of semah mahseer fingerlings reared with different stocking densities in a floating net cage system. The experiment was carried out in the floating net cage located at Cirata Reservoir, Cianjur, West Java, for five months. Fingerlings (total length: 7-8 cm; body weight: 5-6 g) were reared in the floating net cage (stocking density of 50, 75, and 100 ind./m3 with three replications). The fish were fed with a commercial diet (protein content of 40%) given at 6% of biomass twice a day. The parameters observed included weight gain, survival rate, specific growth rate (SGR), and biomass. The results showed that the stocking density of 50 ind./m3 had the best performance in terms of final weight of 15.89 ± 1.43 g, weight gain of 10.48 ± 1.41 g, survival rate of 94.67 ± 4.6%, and specific growth rate of 0.75 ± 0.04%. Based to the results of this study, the stocking density of 50 ind./m3 is the best condition for rearing semah mahseer fingerlings in floating net cages. The findings of this research can be used as the basic information for future aquaculture development of semah mahseer in net cages.

Bonylip barb  (Osteochilus vittatus Valenciennes, 1842) is a   native fish of Indonesia's inland waters which has become a cultivated fish commodity. However, production tends to decrease due to high feed costs. The alternative feed types need to be found to anticipate the problem. Lemna perpusilla Torr is one of macrophytes plant which potentially used as an alternative feed due to high protein content. This study aims to evaluate the growth performance of fish fed with a combination of Lemna and commercial feed. As much of each 14 fishes were rearing in a 45x45x40 cm3 aquarium and fed for 84 days or 12 weeks. There are 5 combinations of feed, i.e feed A (100% commercial feed), B (75% commercial feed + 25% Lemna), C (50% commercial feed + 50% Lemna), D (25% commercial feed + 75% Lemna), and E (100% Lemna). The fishes were fed by commercial feed as much as 3% of the total fish, while administering Lemna at 30% of body weight. Growth performances were measured i.e standard and total length, absolute growth, specific growth rate and survival rate. The results showed that fish was able to growth using combination of commercial feed and Lemna. Data analysis   was conducted descriptively that showed that fish fed by feed C (50% commercial feed + 50% Lemna) produced the highest length and weight, absolute growth and specific growth rate compared to other treatments. The highest survival rate was at fish fed by feed E (100% Lemna).  The use of Lemna as an alternative feed is expected to reduce dependence on commercial feed.

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.

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.

Effects of pH on blood physiological parameters and growth performance of Asian bumblebee catfish (Pseudomystus siamensis) were carried out in laboratory conditions. The experiment was set up in 8 weeks at different pH water levels. The results showed that the cumulative mortality of Asian bumblebee catfish (4 - 6 g/fish) in 24 hpi was 100% at pH = 11, 70.83% at pH = 10 and 62.5% at pH = 3. No mortality of fish was observed at pH = 4, 5, 6, 7, 8, 9 at 24 hpi. The high content of glucose was recorded in fish cultured in water with low (4.02 mmol/L at pH = 3) and high (3.22 mmol/L at pH = 10) pH levels. After 8 weeks of culture, the highest content of glucose was observed at pH = 8 (1.10 mmol/L). The daily weight gain and specific growth rate in weight of fish were 0.02 - 0.08 g/day and 0.35 - 0.99%/day, respectively. The daily length gain specific growth rate in length were 0.02 - 0.04 cm/day and 0.22 - 0.53%/day. The highest survival rate of fish was recorded at pH = 6 (95.96%) and the lowest survival rate of fish was recorded at pH = 8 (60%).
