Sea sponge aquaculture is the process of farming sea sponges under controlled conditions. It has been conducted in the world's oceans for centuries using a number of aquaculture techniques. There are many factors such as light, salinity , pH , dissolved oxygen and the accumulation of waste products that influence the growth rate of sponges.
The maximum load of organisms that can be cultured in a raceway system depends on the species, and particularly on the size of the species. For trout, stocking rates of 30 to 50 kg/m 3 are normal at the end of a rearing cycle, while for marine species, such as sea bass and sea bream, the achievable load is lower, between 15 and 20 kg/m 3.
Dragmacidon lunaecharta, also known as the red ball sponge or red boring sponge, is a species of sea sponge found in the western Atlantic Ocean. It feeds on plankton. These sponges do not attach themselves to rocks or the sea floor but drift in water currents. Its main predators are sea slugs. It has been kept in home aquariums. [citation needed]
Sponge reefs are reefs produced by sea sponges. All modern sponge reefs are formed by hexactinellid sponges, which have an endoskeleton made of silica spicules and are often referred to as "glass sponges", while historically the non-spiculed, calcite -skeletoned archaeocyathid and stromatoporoid sponges were the primary reef-builders.
