Backyard Aquaculture for Steelhead Trout in Coastal Maine, USA

Solar Components has been manufacturing these fiberglass tanks for over 30 years. Tanks are made from Sun-Lite® and are 90% visual light-transmitting. The high light transmission accelerates the growth of algae. They are light weight, shatterproof, non-corrosive. Tanks have been in use worldwide for culturing algae, shrimp, rotifers, clams, lobsters, scallops, finfish, etc.
Tanks are placed in landscapes with raised bed vegetable gardens and small ponds for growing aquatic vegetables and for refuges for beneficial aquatic animals such as frogs.
Tanks are also placed in passive solar greenhouses for thermal storage, irrigation and food production. Photos here show the use of tanks for thermal storage, fish (tilapia), and hydroponic vegetable production in the New Alchemy Institute Ark.
Family Aquaculture Ecosystems in Rural Africa
Rural African farmers are facing food shortages, fragmentation of their land holdings due to accelerated rural population growth, and have little/no additional cash for diversification. Farmers are thus very interested in methods for sustainable intensification that expand the integration of on-farm resources. Small undrainable ponds containing water from runoff and underground seepage were fed with on-farm agricultural wastes. Fish were harvested as needed by use of a reed fence (below), by traps or hooks. Pond muds and waters were used to fertilize vegetable and maize gardens. A plot of land of 639 sq.m (250 sq.m ponds and 139 sq.m gardens) earned $80 producing cabbage, maize, and fish. The aquaculture ecosystem made a substantial contribution to household security (Brummett and Noble, 1995).
