Method and apparatus for rearing post-larvae shrimp

Image Number 5 for United States Patent #4440109.

A method and apparatus for rearing post-larvae shrimp wherein the shrimp are retained for an initial post-larvae period of growth in a first shrimp rearing means including a first habitat means comprising a first plurality of stacked substrates having a first combined total surface area and wherein the shrimp are retained for at least one subsequent period of growth in at least one further shrimp rearing means including a second habitat means comprising a second plurality of stacked substrates having a second combined total surface area greater than the aforesaid first combined total surface area. In further aspects of the invention, unique filtration means and culling means are also disclosed.
