Dear Dr, Kutty,

nowadays, with the intesification of aquaculture  systems the carrying capacity of the ponds must be seen as a key factor. As production areas are limited, productivity must be explored to its maximum to generate profit. Additionally, environmental issues must be considered to reduce aquaculture impacts.

Thanks   Dr Ballester, Than you for the lucid details. 

Dear Dr.Kutty 

Carrying capacity will help you to understand the limitation of production but, there are now unlimited factors to increase your Carrying capacity, where we can now differentiate natural Carrying capacity and human made carrying capacity. The last one, you can understand better all environmental factors negatively affecting your pond natural Carrying Capacity then you can technologically minimize its impacts while maximizing production. Like Water flow system in the pond, bio-chemical factors naturally generated from the pond itself and contributing positively can be assisted by additional one from external environment to keep system running perfect and then artificial evacuating system of side effect factors can also be assist by external factor.

Thank you, Dr Rutebuka.

These are some general remarks. Fish pond carrying capacity is lucidly described by Hepher in his early book on aquaculture. The carrying capacity in the natural state of the pond begins with the lowest, when the stocked fish consumes only the natural feed in the ambient water. Addition of fertilizers to the pond water is the next stage when the carrying capacity is increased to the next higher stage; at the time there is more availability of fish food organisms in the water for the stocked fish to consume. Addition of supplementary feed in the pond increases the carrying capacity of the pond further and this enables the stocked fish to consume the added feed in addition the natural feed in the pond water. The carrying capacity/productivity of the pond can be further increased by improving the quality of the feed.

Thanks
