The semi‐intensive culture system is distinguished by increased stocking rates and the requirement for some level of input, such as food, fertilizer, chemicals, etc.

 Cage culture uses existing water resources (i.e. lakes or ponds) but encloses the fish in a cage or basket, which allows water to pass freely between the fish and the pond or lake. One of the main advantages is the ease of harvesting.

 Fish pens are enclosures installed in open waters that are not too deep for raising fish. The fish have access to the water bottom, unlike in cages.

 Rafts/trays or long lines are mostly used for oyster culture.

 Some improvised containers such as bathroom tubs, big plastic containers, abandoned plank canoe, earthen pots are used to culture fish where the farmer cannot afford the conventional rearing facilities. Some fish farmers in Lagos use these containers for breeding. Apart from breeding purposes, this type of rearing facility is not suitable for commercial fish farming.
