Human nutritionists claimed that Small indigenous fish species (SIS)play a major role in the elimination of malnutrition. SIS have high nutritional value in terms of protein, macro and micro-nutrients, vitamins and minerals and these micronutrients and minerals are not commonly available in other foods. Since these species are normally cooked, the bones also provides as source of calcium. Some small indigenous fish species such as mola (Amblypharyngodon mola) and punti (Puntius sophore) contain more available vitamin-A than any other freshwater fish species like carps. So, polyculture of silver carp and mola or silver carp and punti with large carps may be suitable technology for rural poor who would allow simultaneous production of mola, punti and silver carp for family consumption and sell all other large carps for cash crop.
