The study was carried out to know the present status of Macrobrachium rosenbergii culture in Bagerhat district, Bangladesh from March 2012 to January 2013. Education levels  of farmers were found as illiterate (12.3%), primary (36.19%), secondary (20%), SSC (13.33%), HSC (12.38%) and graduate (5.71%). M. rosenbergii culture was the primary and secondary occupation of 80% and 20% farmers respectively. Average stocking density and production in extensive, improved extensive and semi-intensive culture were 9609, 11502 and 22847 per ha and 193, 284 and 488 kg/ha/year respectively; rearing period ranges from 6-10 months and survival rate varied from 55 to 60%. In improved extensive and semi-intensive culture 82.86% and 71.43% farmers applied farm-made feed instead of company feeds respectively and 11.43% and 37.14% farmers used both feeds. 91.43%, 80% and 68.57% respondents responded on normal to high mortality in extensive, improved extensive and semi-intensive culture respectively. Lack of finance and appropriate technology, scarcity of quality PL, diseases and inadequate extension work were major problems of prawn culture.

An experiment was conducted to compare growth and production performance between all-male and all-female giant freshwater prawn (Macrobrachium rosenbergii) in combination with mola (Amblypharyngodon mola) at the Fisheries Field Laboratory, Bangladesh Agricultural University, Mymensingh, Bangladesh. The research was carried out for a period of 120 days in nine earthen ponds with an average depth of 1.2 m. The experiment had three treatments, viz. polyculture of all-male prawn with mola (stocking density 20,000 ha-1), monoculture of all-male prawn and monoculture of all-female prawn were treated as T1, T2, and T3, respectively with three replications of each and prawn stocking density was 30,000 ha-1 in all the treatments. Formulated sinking feeds were applied twice daily for prawn, and assuming 80% survival feeding rates were gradually reduced to 10-5% of body weight from the beginning to the last month. All water quality parameters (except transparency, chlorophyll-a and plankton) did not vary statistically significantly (P>0.05) among the treatments. Survival of prawn in respective of gender was lower in monoculture than in polyculture with mola, but did not vary significantly (P>0.05). Considering growth and production performance in all treatments, the male prawn showed better growth and production performance than female prawn and the highest gross and net production was recorded in treatment T1, therefore, polyculture of all-male prawn with mola is better than monoculture.DOI: http://dx.doi.org/10.3329/jesnr.v4i2.10163  J.

The present study was investigated the protective efficacy of Zingiber officinale extract enriched diets at 0 g, 0.01 g, 0.1 g, and 1.0 g per kilogram in giant freshwater prawn, Macrobrachium rosenbergii (de Man) against Vibrio alginolyticus. The total hemocyes (THC) significantly increased in prawn fed at 0.1 g and 1.0 g diets on weeks 1 and 2 and all the doses of the diet on week 4 as compared with control against V. alginolyticus. The prophenoloxidase (proPO) activity significantly enhanced all doses of the diet during the experiment as compared to control. The respiratory burst (RB) activity significantly enhanced when prawns were received at 0.1 g and 1.0 g diets on first week and all the doses of the diet on fourth week. The superoxide dimutase (SOD) activity did not significant change between weeks 1 and 2, but it was enhanced on fourth week at 0.1 g and 1.0 g diets. The phogocytic activity was significantly enhanced in all the doses of the diet during the experiment. The clearance efficiency was significantly increased in 0.1 g and 1.0 g diets between weeks 1 and 2 and all the doses of the diet on week 4 as compared with control. The survival rate was 70% and 83% with 0.1 g and 1.0 g diets compared with 0.01 g diet in M. rosenbergii against V. alginolyticus. Therefore, this present results suggested that feed supplementation with Z. officinale positively modulate the immune system and protect M. rosenbergii from V. alginolyticus infection.

Wacana pakan bouyancy pada pemeliharaan larva udang galah muncul karena dugaan untuk meratakan keberadaan pakan di kolom air dan memudahkan larva dalam menangkap pakan sehingga meningkatkan keseragaman ukuran larva pada D10 keatas, menekan laju kanibalisme, mempercepat grow rate dan meningkatkan survival rate. Percobaan ini dilakukan di bak di dalam hapa mini berukuran 100x100x50 cm selama 30 hari; menggunakan larva udang galah D7. Kepadatan tebar 200-300 ekor/L. Pakan bouyancy diberikan 3 kali/hari dengan takaran antara 10-30% bobot biomassa. Percobaan diulang 2 kali. Kajian pemberian pakan bouyancy dilakukan menggunakan bahan pakan berupa susu 150 gr, terigu 150 gr, telur 8 butir, minyak cumi 10 gr, cumi-cumi 150 gr, yeast 5 gr vit C 0,5 gr dan pewarna makanan. Untuk mengoptimalkan daya apung ekstrusi pakan dilakukan secara sederhana dengan menggunakan mixer dan reaksi dari yeast dan gula menghasilkan gas ke pori-pori pakan. Beberapa parameter yang diamati sebagai bahan konsiderasi dari aspek biologis antara lain daya apung pakan, keseragaman ukuran larva, laju pertumbuhan, umur larva, survival rate dan laju konsumsi. Dari hasil percobaan diperoleh daya apung pakan dikolom air bertahan paling lama satu jam. Keseragaman ukuran larva pada D10 keatas sebesar 70%, laju pertumbuhan tercepat diperoleh pada D14 dengan ukuran 10 mm (7%), umur larva yang tercepat masuk stadia Post Larva terjadi pada stadia D20 (5%) dan survival rate sebesar 40% yang dihasilkan selama masa pemeliharaan. Kata Kunci: Larva Udang Galah, Pakan Bouyancy dan Ekstrusi The discourse of bouyancy feed in the breeding of giant freshwater prawn larva appears to distribute evenly the feed in the water column and to ease the larva in catching the feed to improve uniformity of larva size from D10 to up, pressing its cannibalism, improving its grow rate and survival rate. This research was conducted in fairish micronet 100x100x50 cm for 30 days; using Larva Giant freshwater prawn larva (D7). The density of disperse was 200-300 larva/L. Bouyancy feed was given 3 times/day by measuring around 10-30% weight of biomass. It was repeated 2 times. Bouyancy feed was made of several materials, they are: 150 gr of milk, 150 gr of wheat, 8 pieces of egg, 10 ml of Squid oil, 150 gr Squid, 5 gr yeast, 0,5 gr of Vitamin C and food coloured. To optimize the exstrution of feed, it is conducted simply by using mixer and reaction of sugar and yeast yielded gas to pore the feed. Some parameters observed as biological aspects such as buoyancy feed, uniformity of larva size growth rate, age of larva, survival rate and consumption rate. The result showed that the buoyancy feed could survive for one hour. The uniformity of larva size at D10 to up was gained about 70%, the fastest growth rate was obtained at D14 at the size of 10 mm ( 7%), the fastest larvea age entering Post Larva stage occurred at stage D20 ( 5%). Survival rate gained during the treatment was 40%. Keywords: Giant freshwater prawn larva, bouyancy feed and ekstrution

Giant Freshwater Prawn

The effects of mola (Amblypharyngodon mola) at different densities in polyculture with freshwater prawn (Macrobrachium rosenbergii) were investigated at the Fisheries Field Laboratory, Bangladesh Agricultural University,  Mymensingh. The experiment had three treatments, viz. prawn + 1 mola m-2, prawn + 1.5 mola m-2 and prawn + 2 mola m-2 and were treated as T1, T2, and T3, respectively with three replications in each. Prawn stocking density was  same (3 juvenile m-2) in all treatments. Feeds were applied twice daily for prawn. Assuming 80% survival, feeding  rates were gradually reduced to 10-5% of body weight from the beginning to the last month. Water quality parameters  (except transparency, chlorophyll-a) did not vary significantly (P>0.05). Weight gain, SGR (% body weight), gross and  net production of prawn were not significantly different (P>0.05). Higher total production was recorded in T3 (574.61  ±39.58 kg ha-1) followed by TI (531.65±42.40 kg ha-1) and T2 (514.75±77.91 kg ha-1). It was found that addition of  mola at different densities had no effects on survival and production performance of prawn. Therefore, nutrient-dense mola may be stocked as an additional species with freshwater prawn. It might be concluded that treatment T3 was better proposition for prawn-mola polyculture.
