Freshwater prawn farming in India: Status, prospects


Freshwater prawn farming in India developed in 1999 due to a sudden surge in demand in response to the de-cline in marine shrimp production caused by White Spot Syndrome Virus and the Supreme Court judgment on coastal regulation zones (CRZ). Freshwater aquaculture has not been included under the recently enacted CRZ Act and is largely free of the licensing requirements from the Aquaculture Authority of India that are other-wise obligatory for marine shrimp farming. Farming of the giant freshwater prawn, Macrobrachi-um rosenbergii or scampi in Indian trade, the most impor-tant species, has evolved from a traditional activity in the coastal provinces to a modern enterprise. About 60 other species support sizeable capture fisheries in different parts of the country, but their suitability for culture is un-known. Average annual productivity from farming activi-ties is 1.05 mt/ha – higher than the typical 0.92 mt/ha for marine shrimp farming, despite the lower total area under freshwater prawn culture.

    • "The freshwater prawn M. rosenbergii has high potential as an aquaculture species. It is suitable for farming management, feeds on commercial feed, presents market acceptance , and shows good growth performance in cage (Cuvin-Aralar, Aralar, Laron & Rosario 2007) or pond (Nair & Salin 2006) cultivation, even in cold regions (Silverthorn & Reese 1978). Despite its attributes for farming, the heterogeneous individual growth turns out to be a disadvantage to the increase in its aquaculture production. "

    ABSTRACT: A study was carried out to determine the effects of cold shock and 17α-methyl testosterone hormone on growth in male morphotypes of giant freshwater prawn Macrobrachium rosenbergii. Juvenile males were exposed at 18 ± 0.25°C for 24 h with normal feed and cultured at 27 ± 0.7°C for 70 days as well as administrated feed with hormone separately at 400 mg kg−1 feed for the first 30 days of culture period (70 days). The growth (Mean ± SD) of male juveniles at harvest was closely homogenous in the cold shock (CLS) treated group; while it was heterogeneous in hormone-treated (MH) and control (CO) groups. Although total body weight of blue claw (BC) males was not significantly different in the controls and the treatments, the 2nd pereiopods (claw) weight and length of the BC was significantly lower in CLS (0.52 ± 0.05 g, 10.02 ± 0.65 cm) than that in the CO (0.71 ± 0.16 g, 12.53 ± 0.57 cm) and MH (0.75 ± 0.08 g, 12.85 ± 1.18 cm) treatments. Survival of prawns was similar in treatments. The morphotypes of male prawn were significantly different with 59% of BC males with small-sized claws in CLS and, 45% and 30% of BC males with large-sized claws in MH and CO respectively. Cold shock adversely affected male morphotypes of the prawn so that numbers of BC males with small-sized claw was the highest in CLS tank. However, the CLS treatment resulted in more uniform marketable prawns and suggested a high production of BC males in an all-male culture system.

    • "The seed prices have always been fluctuating, mostly governed by the competing hatcheries and fluctuating demand. The price per 1000 PL declined progressively from an all time high of about US$ 30 in late 2000 to US$ 12 during 2001–2003, and to <US$ 4 in 2004, but again improved, and remained around US$ 5–7 (Nair & Salin 2005, 2006) for over 6 years until 2010, while the PL produced from wild broodstock sourced in Kerala almost always fetched higher price of US$ 8–9 per 1000. Prawn seed prices are however, showing signs of improvement, and by June 2011 prices have reached the level of US$ 12–13 per 1000 (excluding packing and freight Table 1 Farmed area and production of Macrobrachium rosenbergii in coastal states of India (2003–2004 to 2009–2010) (source: MPEDA, India) States 2003–2004 2004–2005 2005–2006 2006–2007 2007–2008 2008–2009 2009–2010 "

    ABSTRACT: Freshwater prawn production in India that includes farming and wild capture of the giant freshwater prawn, Macrobrachium rosenbergii and the monsoon river prawn, M. malcolmsonii has increased steadily since 1999 reaching a peak output of 42 780 t in 2005, but then declined to 6568 t in 2009–2010. Stunted growth and diseases in ponds because of poor seed quality and the broodstock which had been inbred over several generations; pond water quality issues; and increased cost of production on account of feed, labour and the mandatory certification requirements are suggested to be some of the factors leading to the production declines. While majority of the output occurs in Andhra Pradesh, single crop paddy–prawn production systems in the low-lying fields of Kerala have helped gradual transformation to a sustainable, organic mode of farming of both rice and prawns, suitable for other states of India. Although the trends by June 2011 indicate that the sector is set to a revival, future prospects of freshwater prawn farming in India will also depend on the expansion of whiteleg shrimp Litopenaeus vannamei that was introduced recently in India and provided a more profitable opportunity for farming.
