Response Analysis Of Urban Vaname (Litopenaeus Vannamei) Which Is Exposed to Crude Protein Zoothamniumpenaei Oral and Maintained In Ponds

ABSTRACTThe objectives of this study were immune response, specific growth rate and survival rate of shrimp vaname (Litopenaeus vannamei) in ponds. The research method used was experimental to know the effect of feed use and added crude protein Zoothamnium penaei on vaname shrimp (Lithopenaeus vannamei) in pond. The sample used is shrimp vaname (Lithopenaeus vannamei) as much as 10,000 heads of juvenile stadia. The food used is commercial feed added crude protein Zoothamnium penaei with a dose of 150 μl / head, which is given 7 times every 7 days interval from the age of 1 day up to Shrimp aged 56 days in ponds. The results showed that there was an increase of immune response (increase of THC and DHC) due to feeding added by Zoothamnium penaei crude. The highest total of Haemocytes (THC) occurred in commercial-fed shrimp and added crude protein ie 56,58 x 106 cell / ml, And the lowest in shrimp shrimp that is not given its crude protein 23.57 x 106 cells / ml. Similarly, the highest Differential Haemosite Count (DHC) also occurred in shrimps fed commercial and added crude protein, 26.57% aged 60 days in ponds and 14.99% low on shrimp not given 90 day crude protein in ponds . Results of parasite shrimp infestation examination exposed with crude protein showed that the highest Zoothamnium penaei infestation was obtained in shrimp fed with artificial feed and not added crude protein Zoothamnium penaei that is 63,35% in shrimp age 90 days. While the shrimp were given artificial feed and added crude protein Zoothamnium penaei infestation Zoothamnium penaei highest of 14.27% in 90 days old shrimp.The highest specific rate of vaname shrimp growth also occurred in shrimp fed commercial and added crude protein Zoothamnium penaei highest of 53.46% and the lowest 16.15% in shrimps aged 90 days in ponds. The highest shrimp life occurrence occurred in commercial vaname shrimp and added crude protein Zoothamnium penaei age of 90 days which has a higher tendency than shrimp that is not given crude protein that is 72% and 21%. The addition of Zoothamnium crude protein to commercial feed as immunostimulant material may enhance immune response, specific growth and shelf life of 30, 60 and 90 days old shrimp in ponds, so that it can be developed as an immunostimulant material.Keyword: Litopenaeus Vannamei, Zoothamnium penaei, udang vanamei

The objective of this study was evaluate the influence of feeding bullfrog tadpoles on commercial feed containing 28% crude protein (CP), on their digestive enzyme performance and activities. The experiment lasted 60 days, at the density of one tadpole/L in boxes containing 30 L water. A hundred and twenty tadpoles at the 25 Gosner stage averaging weight and length was 0.046 g and 6.22 mm, respectively, were used. Survival rate, length, final weight, weight gain, feed consumption, apparent food conversion, specific growth rate and activities of chime, amylase, lipase and trypisin were the parameters evaluated, biweekly, in five biometries. Quadratic effect was observed for the length and the weight. There was larger growth of the tadpoles from the 15th to the 45th day (19.82 mm). On the 15th day, the tadpoles presented the largest specific growth rate (16.93%/day), and the largest weight gain (5.460 g), feed intake (14.099 g) and the best apparent food conversion (2.46) was from the 45th to the 60th day. The specific activity of amylase was 205 times greater at 60 days when compared to the beginning of the experiment. The results demonstrated that, for the three enzymes studied, the action capacity over the tadpole chime increased significantly after the 30th experimental day. Moreover, they suggested a greater capacity of tadpoles to digest carbohydrates in detriment to proteins, and this fact was accentuated in the initial phase of the exogenous feeding of this amphibian. The commercial feed with 28% CP provide good performance in the bullfrog tadpoles, indicating the juvenile formation within commercial bullfrog farming standards.

Litopenaeus vannamei is a leading commodity whose economic value. Targets of vannamei’s production increasing every year. One of important factor in the success of shrimp farming is feed. Research about feed fish directed to the creation of feed fish whose economical and safe for the environment, therefore is required an efforts to provide alternative feed through feed supplement. One of the material that can be supplemented in feed is chitosan. Chitosan can increase the specific growth rate and protein retention of vannamei. This study aims to determine the effect of chitosan supplementation in commercial feed for specific growth rate and protein retention of Litopenaeus vannamei. The research method used was completely randomized design (RAL) and performed with five treatments chitosan supplementation (0%, 1%, 2%, 3% dan 4%) experimental animal used was ten shrimps as five replication in each treatment. The main parameters were observed are specific growth rate and protein retention of vaname. Supporting parameters were observed is water quality. The results showed that chitosan supplementation in commercial feed for 30 days of maintenance give an effect on the specific growth rate and protein retention of vaname. The highest specific growth rate was obtained in treatment with 4% chitosan supplementation that not significantly different with treatment 3% chitosan supplementation. Protein retention was incresed in treatment with 4% chitosan supplementation that not significantly different with treatment 3% chitosan supplementation.

The angel fish Pterophyllum scalare is one of the main species of ornamental interest and widely exploited in Colombia for export. Objective. To evaluate the influence on growth and survival of juvenile P. scalare veil variety fed with Enchytraeus buchholzi. Materials and methods. Ten juveniles per fish tank were randomly distributed among nine fish tanks and then treated with three different diets (D1, D2 and D3): commercial feed containing 45% of crude protein (CP) (D1); commercial feed containing 45% of CP + E. buchholzi with 11.6% of CP (D2) and E. buchholzi alone with 11.6% of CP (D3). Animals were fed during 28 days and final weight (FW), final standard length (FSL), weight gain (WG), gain in standard length (GSL), specific growth rate (SGR), and survival were measured. Results. Significant differences were observed (p <0.05) for the variables FW and FSL. Individuals fed with diet D2 showed higher FW and FSL than those fed with diet D1. The best growth performance was in overall obtained with D2 and were not significantly different (p >0.05) to those observed in juveniles fed with D3. Conclusions. Based upon our results, we recommend E. buchholzi to be used as a supplement to the artificial diet instead of a diet on its own. The adequate proportion in the diet must be known for its optimal use.Key words: growth, live food, angelfish, survival.

The growth and survival of Litopenaeus vannamei post larvae was measured in controlled different salinities condition 35ppt (T1), 40ppt (T2), 45ppt (T3) and 50ppt (T4) were maintained. Group of Shrimp post larvae (weight 0.032 g ± 0.002) were stocked at a density of 35 nos. /aquarium in above salinity ranges. Animals were fed with commercial feed (35% Crude Protein) @ 5% of body weight four times a day. The results indicate that higher SGR was observed in T2 (1.99±0.08) followed by T1 (1.75±0.07), T3 (1.54±0.06) and T4 (1.49±0.17). Highest survival (100 %) was recorded in T1 followed by T2 (96.42%), T3 (94.99%) and T4 (74.21%). From the results of the present study it could be seen that higher salinity significantly reduced the growth and survival of L. vannamei but will also open study area of physiological adaption of animal at higher saline water in performance of organisms.
