Introduction: One of the principal potentials in the country is the existence of unconventional water, which is considered an environmental challenge in the country. Due to the lack of acceptance of these water resources by agriculture, the aquaculture industry can reduce the pressure on freshwater resources. Also, the production of aquaculture products can take a step in this direction. In this regard, Vanami shrimp culture was done in unusual waters in earthen ponds.
Materials & Methods: Stocking with larva post 15 was done for 100 days in one-hectare ponds. Health factors, toxins and heavy metals were investigated during the period in the water and aquatic environment. Water physicochemical, nutritional and growth indicators were investigated during the period. Growth and nutrition factors, average body length and weight, food conversion ratio, survival rate, harvested shrimp and eaten food were investigated.
Results: The breeding results of Vanami shrimp during the period showed that the average weight and total length were recorded as 23.43 ± 0.54 grams and 133.44 ± 3.2 mm in ponds with normal survival. In ponds with low survival, shrimp growth was They reached over 30 grams. The food conversion ratio was recorded in the range of 1.1-2.1. The survival rate of shrimp in the ponds was calculated to be 58-80%. The results of the weight of shrimps in the earthen pool on days 0, 30, 60, 90 and 105 of cultivation were 0.005, 4.2±0.17, 10.85±0.26, 18±0.94 and 43±0.54, respectively. 23/gram was registered. Also, the total length of shrimp was recorded as 10, 78.3±0.97, 111±1.58, 128.97±2.2 and 133.44±3.2 mm, respectively. The analysis of the results showed that the growth and nutrition indicators during the breeding period have a good trend.
Conclusion: The investigations of the water, sanitary, heavy metals and toxins indicators in the shrimp and water showed that the breeding in these effluents is within the limits of human consumption. It is standard. Considering the potential of shrimp breeding in sugarcane drains, it is possible to create employment and produce aquatic animals by following the standards of aquaculture. Supplying suitable food, preparing post with suitable size and price can help to increase productivity. |
