The trend of using probiotics in aquaculture is increasing due to research results indicating their ability to increase production and prevent disease in farm animals. The development of suitable probiotics for bio-control in aquaculture would result in less reliance on chemicals and antibiotics and result in a better environment. The production of high quality larvae in scampi is very difficult, since the disease out breaks are the major constraints in scampi hatcheries. Controlling diseases through antibiotics has been widely criticized for their negative impacts, so alternate methods needed to be developed to produce high quality scampi larvae. Application of water probiotics, soil probiotics and reduction of salinity are the methods gaining importance in controlling pathogen in scampi larvae. The larval rearing tanks are divided into four chambers for our convenience. The probiotics treated tanks are considered as experimental and without probiotics treated are considered as control. The water probiotics namely C.P (Super Biotic) and Biodream (Probiotic contains Bacillus sp. and Streptococcus sp.) was added in the experimental tanks alone @ 5ppm each @ 5- 10 ppm from Zoea stage-II onwards and probiotics Zymatin @ 5ppm was added after the appearance of post larval stage in experimental tanks. In addition to probiotics 0.05 ppm of Treflan was also added both experimental and control tanks to prevent the fungal disease. Water temperature, pH, dissolved oxygen, NH3 and H2S were found better in trials with probiotics. In this experiment, the survival rate of the nauplii of both control and experimental tanks were more or less same. The survival rate of Zoea reared in the experimental tanks was higher (84%) than that of control tanks (62%). The survival rate of all the post larval stages (PL 1- PL-10) was higher in experimental tanks than that of control tanks. Water quality parameters are also influenced by the addition of probiotics, in this experiment the dissolved oxygen was higher in experimental (6.10 ppm) and lower in control tank (5.50 ppm). The alkalinity (120 ppm) in both control and experimental tank is more or less similar. The Ammonia was higher in control tanks (0.15 ppm) compared experimental tanks (0.12 ppm).

The study was conducted to observe the impact of commercial probiotics application on growth and production performance of fresh water prawn (Macrobrachium rosenbergii) from August 2011 to March 2012. There were four experimental groups viz (a) control or without probiotics treated prawn (T 1), (b) feed probiotics-Zymetin (T 2) treated prawn, (c) soil probiotics-Super PS (T 3) treated prawn and (d) Both Zymetin and Super PS (T 4) treated prawn. Twelve ponds (each 120 m 2) were used where stocking density was 2/m 2 for all treatments and control and each was triplicated. After pond preparation, prawn PL was reared in the nursery pond for 45 days to become juvenile. At the time of stocking in growout ponds, average body weight of juvenile prawn was 1.04 g. After eight months (240 days) of culture, the mean final weight became 39.5 ± 12.03, 43.4 ± 14.91, 48.0 ± 16.73 and 51.6 ± 15.58 g in T 1 , T 2 , T 3 and T 4 respectively. Significance difference was found among all treatments and T 4 showed highest growth. The SGR was found to be 1.50 ± 0.13, 1.53 ± 0.13, 1.58 ± 0.13 and 1.61 ± 0.11 (%BW/day) in T 1 , T 2 , T 3 and T 4 respectively and the difference was significant. The survival rate did not differ significantly but highest survival rate was found in T 4 (90%). The average FCR was significantly lowest in T 4 (1.39) and highest in T 1 (1.9). The net average production was found to be significantly higher in T 4 (914 kg/ha) which was 35% and 21 % higher than the control group (T 1) and feed probiotics (T 2) respectively. Water and soil quality parameters were measured and were within the culturable range. The production of probiotics treated ponds was always higher than without probiotics treated ponds but highest growth and production were found in T 4 where Zymetin and Super PS were used combinedly. The results of this study can be applied in the farmer's pond to increase the total production of prawn in the country.

Prawns are commercially one of the most important marine resources. However, in their early developmental stages, they face challenges related to physico-chemical and environmental changes. This study aimed at investigating the effects of temperature and salinity on egg incubation time, hatching success, larval and postlarval survival of the giant tiger prawn, Penaeus monodon (Fabricius 1798) obtained from the coastal waters of Tanzania. The adult females P. monodon collected off Rufiji delta were left to acclimatize and spawn at 28.5 ± 0.5 °C and 32 ppt in the hatchery. Spawned eggs were incubated at experimental temperatures of 27 °C, 31 °C and 35 °C with three subgroups of salinities of 30 ppt, 35 ppt and 40 ppt. The incubation time was longest (15.2 hours) at 27 °C and 30 ppt, and shortest (10.7 hours) at 35 °C and 40 ppt. Hatching success was highest (85.2%) at 31 °C temperature and 30 ppt salinity, and lowest (69.45%) at 35 °C and 40 ppt. Larval and postlarval survival was sui...
The present study was attempted to examine the combined effects of probiotics, Lactobacillus sporogenes (LS), Bacillus subtilis (BS) and yeast, Saccharomyces cerevisiae (SC) on survival, growth, biochemical changes and energy utilization performance of the freshwater prawn M. rosenbergii post larvae. The probiotics, L. sporogenes (4), B. subtilis (3) and S. cerevisiae (4) were taken and mixed. 1%, 2%, 3% and 4% of LS+BS+SC (4+3+4) was incorporated with basal diet. Diet without probiotics served as control. PL-30 of M. rosenbergii was fed with LS+BS+SC (4+3+4) incorporated diet for a period of 90 days. The growth parameters, such as survival, weight gain, specific growth rate, feed conversion efficiency and protein efficiency rate were significantly (P<0.05) higher in 3% LS+BS+SC incorporated diet fed post larvae (PL) followed by other experimental groups when compared with control. Whereas, the feed conversion ratio was significantly (P<0.05) lower in 3% LS+BS+SC incorporated diet fed PL. Similarly the tissues biochemical composition such as protein, amino acid, carbohydrate and lipid content were significantly (P<0.05) higher in 3% LS+BS+SC incorporated diet fed PL. However, insignificant difference was recorded in moisture content between control and experimental groups. The energy utilization parameters, such as feeding rate, absorption rate, conversion rate, NH 3 excretory rate and metabolic rate were significantly (P<0.05) higher in 3% LS+BS+SC incorporated diet fed PL. Therefore, the probiotics 3% LS+BS+SC incorporated diet fed PL was produced better growth performance.
Fiji has a strong demand for shrimp but farmers have hard time meeting the demand due to inadequate knowledge of local ingredients. A nutritional study was conducted to evaluate the growth performances of juveniles of the freshwater prawn species Macrobrachium rosenbergii. The prawns were fed with low cost formulated diets using locally available ingredients. Two experiments were conducted with six different diets in each of the experiment. In Experiment 1, diets were mainly based on carbohydrate ingredients ( fish meal+wheat, Fish meal+meat bone meal+wheat, Fish bone meal+fish meal+wheat, Meat bone meal+wheat, Meat fish meal+fish meal+wheat and Meat fish meal+wheat). While diets for Experiment 2 were based protein ingredients ( Fish meal+wheat, Fish meal+meat meal, Fish meal+meat meal+crest tilapia pellet, Fish meal+meat meal+copra meal, Fish meal+wheat+pea meal and Crest tilapia pellet). Each experiment (6 diets x 3 replicates) was carried out in the laboratory. Juveniles were fed twice a day for a period of three and four weeks in Experiment 1 and 2 respectively. Results indicated no significant (P>0.05) differences in water quality parameters. All nitrate, nitrite and ammonia concentrations were less than 0.2 mg/L. Fat and crude fiber contents were lowest and highest respectively in crest pellet tilapia (4.60% and 17.98%). Experiment 1 showed slight variations in growth performance. In Experiment 2, crest tilapia pellets indicated better result in weight gain (7.04 ± 2.96 mm), carapace, abdomen and body length (4.74 ± 1.94, 5.57 ± 0.62 and 5.57 ± 0.62), specific growth rate ( 2.38 ± 0.53) and feed intake (1.31 ± 1.19).However, no significant differences (P ≥ 0.05) were observed in either of the experiments. The costs of making each feed was almost same (0.53-0.58 Aus $/Kg). The findings indicate that the ingredient inclusion level for local ingredients available in Fiji could be quite flexible and used successfully for the growth of fresh water prawn juveniles (M .rosenbergii).
Tiger Prawn culture with Red seaweed based feed.pdf
Traditional method of tiger prawn culture is a common practice in Indian Sundarbans which is done without any sound scientific backup , proper feed and water quality management. The shrimp farmers use traditional feed of animal origin that often results in fouling of water quality and disease outbreak in cultured species. The present paper highlights the effect of total replacement of animal ingredients in shrimp feed with floral ingredients on the water quality and shrimp health. Weight gain, condition index, feed conversion ratio (FCR), survival, body pigmentation (astaxanthin level) were analyzed in shrimps along with pond water quality. Higher condition index (C.I.) values, survival rate and gain in shrimp weight were observed in experimental pond (E) compared to control pond (C). Low FCR values were observed in the experimental pond than the control pond. Astaxanthin values in shrimps of the experimental pond were also higher than the control pond which points towards Catenella repens as the source of carotenoid in the shrimp tissue. Cost-benefit analysis also proved better yield and profit in case of experimental pond indicating the sustainability for the present venture.

200 live juveniles of African river prawn (Macrobrachium vollenhovenii) with an average initial weight of (0.7±0.02 g) and an average initial length of (46.34±0.23 mm) were collected from Epe Lagoon and cultured in a rectangular concrete tanks for 56 days. The prawns were fed with 2mm pelletized feed of 35% crude protein at 5% body weight. The Growth parameters were determined and the Weight Gain (WG) at the end of the experiment was 2.5 g, Percentage Weight Gain (PWG) was 31.25%, Specific Growth Rate (SGR) was 0.21%, Feed Conversion Ratio (FCR) was 1.04, Feed Efficiency Ratio (FER) was 0.962, Protein Efficiency Ratio (PER) was 7.14% and Condition factor (K) was 1.35. The equation of the length-weight relationship was W=0.57L 1.33 , a = 0.547, b = 1.33 which shows a negative allometric growth. The Linear correlation coefficient (R) was 0.58. The range of water quality variables analyzed weekly were 6.74-7.90 for pH, 25.7-30.3 0 C for the temperature, 6.71-8.01 mg/L for dissolved oxygen, 0.00-0.03% for salinity, 0.199-0.725 mS/cm for conductivity, 24-48 NTU for turbidity, nitrite was 0.07-0.50 mg/L, nitrate was 1.32-6.63 mg/L and 0.32-1.65 mg/L was recorded for Ammonia. The study has helped developed a method of collection, transportation, culturing in concrete tanks and feeding of prawns with locally formulated diet with prompt check on the water quality. Subsequent work can be carried out in concrete tanks to yield the desired result and serve as a yardstick in subsequent culture using other forms of culture medium.

This study aims to determine the effect of the best RABAL probiotic dose on the media for the maintenance of giant shrimp larvae (Macrobrachium rosenbergii) on the survival, feed conversion, and growth. This research was conducted from March to April 2019 at Brackish Water Aquaculture (Balai Perikanan Budidaya Air Payau, BPBAP) Ujung Batee, Aceh Besar district, Province of Aceh. This study used a Completely Randomized Design (CRD) with 4 levels of treatments and 4 repetitions. The treatments used of RABAL with a dose (A) 0 ppm, (B) 75 ppm, (C) 150 ppm, and (D) 225 ppm. The frequency of administration of RABAL was once a day. The giant prawn larvae used was a larvae stage with an average weight of 0.05 g/larvae. Based on the result of ANOVA test the best value was obtained a treatment D (225 ppm) with absolute weight growth value of 0.16 g ± 0.003, absolute growth length of 1.30 cm ± 0.053, specific growth rate 5.08 ± 0.043, survival rate 96.25 ± 4.787 and feed conversion ratio 0.83 ± 0.013, respectively. The result of this research showed that the administration of RABAL with different doses into maintenance media had a significant effect (P<0.05) on the growth and feed conversion ratio of giant shrimp larvae but did not significant influence (P>0.05) on the survival rate of giant shrimp larvae.

This study was motivated by the need to find a solution to poor egg quality and the resulting mass mortality of hatchery-produced larvae of the tiger prawn, Penaeus monodon. The approach adopted sought to improve the broodstock condition and determine its effect on egg quality using rates of fertilization, hatching and metamorphosis. Broodstock specimens were given four separate dietary treatments (D1-D4), all of which comprised squid and trash fish plus supplements. D2, D3 and D4 were supplemented with bloodworm, bioencapsulated bloodworm and a commercial broodstock diet, respectively. Tricalcic phosphate (Ca 3 (PO 4) 2) was used to enrich the live bloodworm. The bioencapsulated ration performed better than regular bloodworm and other diets. This was evident from the bioencapsulation results which showed the highest rate of hatching, survival of nauplii and larvae metamorphosing into zoea stage.
