The article discusses the basics of cage and pen aquaculture. Factors to consider in site selection; choice of nets, floats, frames, and anchors; and the choice of culture method are also discussed.

The paper investigates the effects of intraperitoneal injections of LHRH-a and domperidone (DOM), given singly or in combination at two injections, on oocyte maturation and spawning in bighead carp, Aristichthys nobilis.

The paper presents bighead carp broodstock management, an integral part of hatchery techniques as it will determine the quality of resulting fry and fingerlings. Proper methods on the selection and management of broodstock were discussed.

The paper presents the result of the study on the polyculture of the different species of carp with tilapia and milkfish. Polyculture does not hamper the growth of primary species but rather increased the production. However, bighead carp and silver grow faster compared to other species.
