3.2.4 Prospects of rearing fish in fresh water
Detailed prospects of rearing fish will be possible. Fingerlings should
be introduced from time to time and growing fish should be carried out.
Advisory services of fishery scinitist be taken in the fresh water. Fish
should be used for human, animal, rearing birds and animals as well as
for making medicinal products and organic manures. The water in tank
will be enriched by tankage will also get enriched by N and P. This
water will be salable for irrigation, without any risk of degradation of
lands.
Tankage of fish rearing enhances biological nitrogen and phosphorus N
and P brings new opportunity for enhancing Nutrient by tanakage.
Researches (Yadav,2014, 2015 and) 2020) have established that for
enhancing productivity by optimum level the recommended chemical doses
of NPK, one fourth of N dose should be supplemented by organic
sources(Anonymous, 2003). The enhanced level by tankage creates new
opportunity for catering the organic dose by 6.5-10 % and phosphorus,
by 10 %. This positive impact shows tremendous prosperity of use of
waste water, which spoil land water condition in the riparian areas. The
utility of fish opens tremendous opportunity in bringing prosperity
