AQUACULTURE

AQUACULTURE

The husbandry of aquatic animals is not a new phenomenon with a tradition of about 4000 years. Ancient practices based on the modifications of natural bodies of water or wetlands to entrap young fish in enclosures until harvest have evolved into more systematic and scientific methods and techniques. Different culture practices are used across the globe in three types of environment namely freshwater, brackish water and marine water.

Popular aqua culture practices include:
Freshwater pond culture
Integrated fish farming
Brackish water culture
Rice-fish culture in paddy fields
Mari culture (oysters, mussels, cockles)

Extensive systems use low stocking densities (5 000-10 000 shrimp post larvae (PL)/ha/crop) with no supplemental feeding, although fertilization may be done to stimulate growth and production of natural food in the water. Water change is effected through tidal means i.e., new water is let in only during high tide and the pond can be drained only at low tide. The ponds used for extensive culture are usually large and may be shallow and not fully cleared of tree stumps. Production is generally low at less than 1 ton per hectare annually. Semi-intensive systems use densities higher than extensive systems (50 000-100 000 shrimp PL/ha/crop) and use supplementary feeding.

Intensive culture uses very high densities of culture organism (200 000-300 000 shrimp PL/ha/crop) and is totally dependent on artificial, formulated feeds. Semi-intensive and intensive cultures are managed by application of inputs (feeds, fertilizers, probiotics and sanitizers) and manipulation of the environment primarily by water management through use of pumps and aerators. Feeding of the stock is done at regular intervals during the day in equal doses from as low as three to as high as six times a day.

Intensive Aqua farming is a viable economic activity and flourishing sector with varied resources and potentials. The vibrancy of the sector can be visualized by the 11fold increase achieved in production in last six decades, thus making India home to more than 10 percent of the global fish diversity and second largest producer of fish in the world. Today Indian Aquaculture industry has evolved from being just a traditional practice to research-driven, commercial farming employing over 14 million people fetching 1.1% of GDP. Springpool offers a wide range of specially designed Aqua feed products, mineral mixtures, probiotics and bio safety products to meet the nutritional requirements of fish and shrimps reared in Indian farming conditions. Our nutritionally fortified and scientifically formulated products help in increasing survival rate, optimum weight gain, uniformity and improved feed conversion ratio that are sustainable and eco friendly
