This flexible system provide enough protection to Nile tilapia (Oreochromis niloticus) during cold weather in Egypt and in the same time allows fish to disperse in the pond and feed whenever weather gets warmer. Overwinter greenhouses are placed in earthen ponds whereas plastic covers go well below water surface but not reaching pond bottom. The area beneath greenhouses will be protected against cold winds and act as shelters to tilapia. Whenever, weather warms up as the case in sunny days, fish have the choice to temporarily swim away the green house and grazes natural food or feed artificial feed as shown in the photo with a demand feeder. This type of overwintering facility does not interrupt farming operations whereas fixed parts remains uncovered during warm months and are covered only when cold weather approaches (this is seen in the second photo).

The main features of the culture of abalone (Haliotis asinine) in concrete pond include a water depth of not more than 1.5 meter, clear water, and flow through water of 5-10 liter/min.; aeration of pond water is practiced. Water pollution is considered the main obstacle that negatively affects hatchery productivity whereas survival is very low due to variety of causes. The low survival leads to the increase of production cost. However, abalone enjoys had demand as well as high price.

Udawalawe tank (reservoir) was constructed in the mid 1960s by damming the Walawe Ganga River to develop the irrigation capacity in a target zone. At full supply level, the tank covers an area of about 3400 ha. The photo shows two fishermen prepare for fishing in Udawalawe tank. In the present, there are there are 47 fiberglass fishing boats operating in the tank with two fishermen for each boat. Fish catch of the tank is compromised of tilapia, Indian carps (catla and rohu), and common carp. Fish production of the tank is estimated by about 270 tons/year whereas about 2100 beneficiaries depend on this tank fishery in their living.
