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.

Tiger Grouper

The experiment aimed to evaluate the optimal level of fermented blood meal used in grow-out diets for tiger grouper, as an alternative protein source to fish meal. Juvenile tiger grouper, initial weight 31.1 ± 2.1 g, were stocked into 1 m x 1 m x 2 m floating net cages at 20 fish cage-1. The treatment applied was isoprotein and isocaloric diets formulated to contain fermented blood meal (FBM) of 0%, 7.5%, 15.0%, 22.5%, and 30.0% replacement of fish meal protein. The diets were fed to the fish twice a day to satiation for 20 weeks. Based on the Tukey test, the fish fed 0%–15.0% FBM demonstrated similar performance (P>0.05) to those fed the control diet (FBM0) in terms of specific growth rate, weight gain, and feed and protein efficiency. Specific growth rate, weight gain, feed efficiency and protein efficiency of the fish fed 22.5%–30.5% FBM were significantly lower (P<0.05) than those of the fish fed control diet (FBM0). However, there was a significant culvilinier decliner in overall fish performance with increasing inclusion of FPM and most notable for weight gain, feed efficiency and feed consumption. Based on regression analysis, the asymptote where fish growth deteriorates as a function of FBM inclusion was determined to be 8.9%. Tiger grouper diets incorporating up to 9% FBM as fish meal replacement had no adverse affects on fish growth and survival.

Eel (Anguilla bicolor) is an Indonesian freshwater commodity that has high economic value but has slow growth. One method to accelerate eel growth is through feeding with the enrichment of essential fatty acids. The aim of this research is to know the increase of growth rate of eel fish fed with the enrichment of essential fatty acids with fish oil and corn oil. The study used 3 treatments and 3 replications ie A (0% corn oil + 0% fish oil), B (1.5% corn oil + 1.5% fish oil), and C (3% corn oil + 3% fish oil). Parameters observed included specific growth rate, total feed consumption, feed efficiency, fat retention, and survival rate. The supporting parameter is water quality. The data obtained were analyzed by analysis of variance and continued by fisher test with 95% confidence interval. The results showed that there was a significant effect (P <0.05) on the growth rate of eel fish fed with the enrichment of essential fatty acids with fish oil and corn oil. Treatment C (3% corn oil + 3% fish oil) is the optimum dose because it has the best growth performance and best feed efficiency that is specific growth rate (4.67%), total feed consumption (262,9 g), feed efficiency (61% ), fat retention (2.805%), and survival rate (80%).

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.

Duplicate groups of seawater-adapted 70-g all-female chinook salmon (Oncorhynchus tshawytscha) were held in flowing seawater (24–29‰; 8–12 °C) corresponding to swimming speeds (SS) of 0.5, 1.0, or 1.5 body lengths (bl)/s for 212 d. Fish were fed either a maximum satiating ration of 75% of maximum ration at each SS. Fish grew four- to fivefold during the study, but neither mean body weight, fork length, specific growth rate, condition factor, nor muscle morphometry was influenced by average SS. However, the SS of individually marked fish were negatively correlated with specific growth rate. At both rations, higher SS increased the internal tissue-carcass ratio, hepatosomatic index, and total body protein. More food was ingested at higher SS resulting in reduced feed efficiency. SS did not alter the plasma L-thyroxine (T4) concentration, but increased the plasma 3,5,3′-triiodo-L-thyronine (T3) concentration and T3/T4 ratio. In part, this may reflect the greater food intake at higher SS. The reduced ration depressed all aspects of growth and at 212 d tended to depress both plasma T4 and T3, but did not alter feed efficiency. We conclude that exercise over the range of 0.5–1.5 bl/s does not enhance growth, but reduces feed efficiency in seawater-adapted chinook salmon.

To evaluate the effects of two diets on the growth performance and nutrient contents of gulsha, Mystus cavasius was conducted. Growth performance of gulsha was found maximum in rice bran and spirulina feed (treatment T1) and the lowest was observed in commercial feed (treatment T2). Specific growth rate of gulsha was higher in treatment T1 than treatment T2. Treatment T1 had the best proximate composition (moisture 77.28%, ash 3.45%, lipid 4.31% and protein content 15.05%) and nutrient contents (calcium 115.6 mg/100g, phosphorous 166.7 mg/100g, potassium 207.23 mg/100g, magnesium 25.97 mg/100g, iron 1.85 mg/100g and manganese 0.23mg/100g). Therefore, it was found to be better option to produce healthy fish for human consumption.Bangladesh J. Zool. 45(1): 61-71, 2017
