Red tilapia is a one of the economically important fish species. In order to increase growth and feed efficiency, feed restriction strategies can be carried out. This study aims to determine the effect of periodic (weekly) restriction of feed on compensatory growth and physiological responses of red tilapia during the enlargement phase. The activity was carried out at the Fish Breeding Research Center for 4 months. The research method used a completely randomized design (CRD) 4 treatments with 3 replications, namely control (fish were fed daily), 1 (1 fasting day a week), 2 (2 fasting days a week), and 3 (3 fasting days  a week). Fish rearing was conducted on the concrete tub measuring 2 x 1 x 0.8 m3 with a stocking density of 10 fish m-2. During the maintenance period of 120 days the fish were fed satiation twice a day. The results showed significant differences (P <0.05) in the value of weight growth, specific growth rate, daily growth and feed conversion ratio between control and other treatments, but not significantly different from treatment S1. The highest survival value was indicated by S1 treatment. The blood faal values of fish that were given feed restrictions consisting of red blood cells, white blood cells, hematocrit and hemoglobin showed that there was not significantly different than control fish (P> 0.05), which was at normal values. Restriction of feed to 1 day a week showed partial compensatory growth with better feed efficiency than fish fed daily.

Aim: The present investigation was conducted to access the effect of salinity stress on growth performance, survival and biochemical parameters of Gibelion catla under different salinity conditions with an idea to assess the potentiality of this species in inland saline affected areas. Methodology: A 30-day-experiment was conducted in 1000 l (n=10) FRP tanks to study the effect of different salinity levels on the growth and biochemical parameters of catla species. A total of 120 fish (10.4 g) was randomly distributed into four treatments (0, 3, 6 and 9 ppt) with three replicates. The water quality parameters such as pH, temperature, nitrite, nitrate, ammonia, alkalinity and dissolved oxygen were recorded for each treatment on weekly basis, whereas fish sampling was carried out at 0th and 30th day of the experimental period to ascertain survival, weight gain, specific growth rate and feed conversion ratio of the fishes from each treatment. Results: The highest growth rate was found in control subsequently in 3 and 6 ppt and the survival rate was 96.67, 83.33, 76.67 and 0% against 0, 3, 6 and 9 ppt, respectively. The red blood cells (3.65×106 μl) and haemoglobin concentration, (8.17 gm dl-1) were also higher in control fish, followed by 3 and 6 ppt. However, white blood cells (24.40×106 μl) and glucose level (123.23 mg dl-1) were higher at 6 ppt, compared to control. Plasma protein level of fish at control (0 ppt salinity) was significantly higher than those of fish exposed to 3 and 6 ppt salinities. Interpretation: The present investigation revealed that an increase in salinity level had a significant impact on the growth and physiology of Gibelion catla. However, this species can be reared in low saline areas for some time which will not only help in the utilization of salt affected areas but will also help in the generation of employment and income.

An experiment was carried out to test the effect of Sesame residue (SR) inclusion in the diets of growing Yankasa ram lambs on haematological and serum biochemical parameters. Twelve (12) Yankasa ram lambs with initial body weight of 20.08±3.08kg were allotted to three dietary treatments containing 0, 20 and 30% SR (A, B and C). A completely randomized design was used for the study which lasted twelve (12) weeks. The haemetology results revealed that the white blood cells (12.85-16.85 109/L), red blood cells (1.49-2.04 1012/L), haemoglobin, mean corpuscular haemoglobin concentration (MCHC), mean corpuscular haemoglobin (MCH) (39.85-48.00 pg), mean corpuscular volume (MCV) and lymphocytes differed significantly (P<0.05) among the treatments. Lambs fed 30% SR had the highest MCV, MCH, MCHC and lymphocyte values. Serum biochemical analysis results revealed that lambs fed 20% and 30% SR had higher alkaline phosphatase, total protein and globulin values than lambs fed 0%SR. However, SR inclusion in the diets did not affect calcium and phosphorus levels of the lambs. In conclusion, including sesame residue at 30% in the diets of growing Yankasa ram lambs had no observable adverse effect on haematological and serum biochemical parameters.

Vannamei shrimp is a fishery commodity that has important economic value for Indonesia. This is indicated by the increasing number and value of exports of this commodity. One of the efforts to encourage the production of vaname shrimp is through the use of probiotics. sanolife-MIC is a probiotic widely used in shrimp culture. The aim of the study was to analyze the feed profile and biological performance of Vaname PL 10 shrimp fed pellets with the Sanolife MIC-S probiotic capsule at different doses. The research method used is an experimental method using a completely randomized design (CRD) with four treatments (A: probiotic 0 gr/kg feed; B: probiotic 10 gr/kg feed; C: probiotic 12 gr/kg feed; D: probiotic 14 g/kg feed) and three replicates. What was tested in the study were probiotic profile tests, growth, feed efficiency and feed conversion. The data obtained were analyzed using ANOVA. The results showed that the feed profile that was encapsulated using sanolife MIC-S, the protein value, moisture content and ash content for the feed were shown by treatment B. The best fat content was treatment C. The best crude fiber content was treatment D. Weight growth rate, ratio The best feed conversion and feed efficiency was shown by treatment B, while the length growth and survival was indicated by treatment C.
