The experiment was conducted in 3 treatments with 5 replicates. The 1 day post hatched (1 dph) shrimp were then fed twice daily with experimental diets for 60 days. The results of this study indicated that the larvae fed with the MED showed a higher (P 0.05). Enzyme activities were also focused on, the results indicated that the protease, amylase and lipase activity of the larvae fed with the microencapsulated diet was much higher than the other experimental diets (P< 0.05).

The result showed that average daily weight gain were 0.90 + 0.38, 1.63 + 0.30, 0.83 + 0.13 and1.37 + 0.25 g/fish/day, respectively. Tilapia were fed with 3 and 9 % tuna oil supplemented diets showed better growth (p 0.05) . The fatty acids level of edible flesh of fish fed with tuna oil supplemented diets of 0, 3, 6 and 9% were studied. EPA levels were 0.14 + 0.03, 0.19 + 0.04, 0.28 + 0.04 and 0.36 + 0.05 mg/g d...

The study was divided into two trials. Firstly, the pepsin digestibility of raw material and snail meal substitution for fish meal diets was investigated. The results indicated that the protein digestibility of diets containing snail meal were decreased (p<0.05) by increasing percentage of snail meal ( from 0 to 100%). The percentages of digestibility were 82.86 and 74.80% for 0 and 100% substitution, respectively. Secondly, the growth performance and feed efficiency were conducted on giant freshwater prawn fed with isonitrogenous (34±1% CP) and isocalorics (3,100±100 DE kcal/kg) diets containing 0, 25, 50, 75 and 100% golden apple snail meal substitution for fish meal. The results indicated that there were no significant difference (p>0.05) on growth performances and feed efficiency during the first ...

They involved improving growth performance, metabolism and immune system of shrimp especially in case of high plant basal feed. Since the insufficient amount of fish meal production due to unsustainable fishery problems, soybean meal has been a major alternative protein source but phytic acid in the plant was the factor to reduced bioavailable of minerals. So, this research studied the effect of trace mineral concentration in the diets on growth performance and immune response of white shrimps Litopenaeus vannamei. The trial was assigned in CRD with 3 treatments and each of 10 replicates. The diets with 37% crude protein and 5% crude fat were formulated and top up with different trace mineral levels of 1x, 2x and 3x. All diets were fed to shrimps for 28 days and the results showed no significant differences ( P >0.05) on all growth performance parameters. Anyway, the numerical values of growth pe...

The growth trial was assigned in a completely randomized design (CRD) with four treatments and 5 replicates of each, T1: a fishmeal-based control containing 15% fish meal and 3 diets with graded levels of methanotroph bacteria meal, namely T2: 5% methanotroph bacteria meal, T3: 10% methanotroph bacteria meal, and T4: 15% methanotroph bacteria meal. Shrimp were fed ad libitum for 6 weeks on trial diets to assess growth. Subsequent to the growth trial, three replicates of the same groups were exposed to V. parahaemolyticus by a single bath challenge and held for a further 15 days on the same diets as the growth stu...

This triggered a search for alternative dietary protein sources for shrimp production. We studied the consequences of replacing FM with a defatted insect meal, ŸnMealTM (YM), comprised of yellow mealworm (Tenebrio molitor). Growth and immune parameters of juvenile Pacific white shrimp (Litopenaeus vannanmei) were compared after an eight-week feeding trial. Shrimp were kept in aquaria with densities of 60 and 40 shrimp/m2 and fed one of five diets in which a proportion of FM was replaced by YM. All diets were isoproteic, isoenergetic, and balanced in lysine and methionine. After the feeding trial, shrimp were challenged with pathogenic bacteria (Vibrio parahaemolyticus). Growth and feed conversion parameters improved when YM was included in shrimp diets; with the highest weight gain and best food conversion ratio (FCR) achieved when 50% of FM was replaced by YM versus ...

The gradual melatonin levels of Control (0 mg/kg melatonin), Mt0.05 (50 mg/kg melatonin) and Mt0.25 (250 mg/kg melatonin) in the diet mixed in isonitrogenous and isocaloric of 37% crude protein and 9.3% crude lipid was applied to the first sexual maturation female catfish. Estradiol analysis, maturation analysis, breeding performance and the larval quality were evaluated. The exogenous melatonin treatment increased the fecundity, gonadosomatic index and egg diameter (p <0.05) after eight weeks of treatment. During artificial spawning, the melatonin enhanced the egg production and the larval survival rate (p <0.05). The current results supported the concept of exogenous melatonin treatment may enhance the first sexual stage of maturation in the C. macrocephalus.
