Shrimp species and their suitability

Many factors must be considered when a farmer is deciding which species of shrimp he should culture. Due to its large size and high price, Penaeus monodon and P. indicus are generally considered for farming. It has also been seen that both these species are suitable for farming in Kerala's environment. Apart from these candidate species other commercially important species such as Metapenaeus ensis, M. monoceros, M. brevicornis, Penaeus semisulcatus and P. merguiensis are also potential species that can be grown in India. Another potential candidate species that is flooding international market is the White leg shrimp, Penaeus vannamei. Although the Government of India has not yet given sanctions to culture it in the country, many Asian countries have already started to culture this species.

Advantages of P. monodon

• It attains a large size. Shrimp with a size of 10 to 12 pieces/kg are common, and sizes of 5 to 7 pieces/kg have been grown in ponds.
• It is the fastest growing of all shrimp tested for culture. In ponds, juveniles of 3 cm in length have been grown to a size of 75 to 100 g in only five to six months.
• Due to its large size, it brings a high price to the farmer. At peak seasons it demands over Rs. 450 per kg in India.
• It can tolerate a wide range of salinity, 0.2 to 70 ppt. Salinity within the range of 10 to 25 ppt has no appreciable effect on growth when food is sufficient. Growth is reported to be slower at very low salinities.
• It can tolerate temperatures up to at least 37.5°C. Mortalities occur at temperatures below 12°C only.
• It grows rapidly when fed either with animal or vegetable protein.
• Food conversion ratios are favourable. Values as low as 1.8:1 have been reported from Taiwan.
• It is hardy and not greatly disturbed by handling.

Advantages of P. indicus

• This shrimp grows to a fairly large size and brings a good price.
• It is fairly fast growing, especially when young. Cultured in tanks at a density of 15/m2, it reached a size of 14 g in 16 weeks. In polyculture with milkfish in earthen ponds, females grew to about 28 g and males to about 12 g in 160 days.
• Survival is high during the first three months of growth or up to a size of about 10 cm.
• Wild seeds are usually abundant in estuaries near areas where the adults are present.
• Gravid females are relatively easy to obtain from the wild in numbers sufficient to operate a hatchery.
• Females can be matured in captivity with relative ease.
• This shrimp moves out of a pond with water discharge, making harvesting easy.
• Good growth has been obtained in intensive culture with a feed having 40 percent protein, which is lower than that required for some other species.
• The exoskeleton is relatively thin, giving greater portion of edible meat to total weight.
