The manual describes the procedures and techniques to follow for short and long duration transport of prawn fry. Regulations for acceptance and handling of wet shipment and the acclimation of the fry are also covered.

The manual on milkfish (Chanos chanos) broodstock management covers the following topics: reproductive biology; sources of broodstock; holding facilities for broodstock; feeding; determination of gonadal development; spawning and egg collection; transport of spawned eggs; determination of percent viable eggs; and determination of hatching rate.

The manual addresses sea bass (Lates calcarifer) fry production in the hatchery. It describes the principles and practical procedures for rearing sea bass - from eggs until metamorphosis - as practiced by the SEAFDEC Aquaculture Department in Tigbauan, Iloilo, Philippines. It is presented under the following main section headings: General principles; biology; Selecting a suitable site; Design - tank systems, seawater supply system, freshwater supply system, aeration system, other facilities; Broodstock - source of breeders, breeding techniques; Egg collection, transport and hatching; Larval rearing - stocking density, feed types and feeding management, water management size-grading of larvae; Harvest and transport of fry; and, Propagation of larval food - Chorella, Brachionus, Artemia, Moina.

This manual is intended for fish farmers, extension workers and others in their initial efforts to produce marketable sugpo (Penaeus monodon) for local consumption or export. Information is presented on pond preparation, stocking, transfer from nursery to rearing pond, rearing, harvesting, processing and transport. Appendices deal with the control of pests and predators, diseases, fertilization, and the estimation of rate of supplementary feeding.

One of the major problems in the mass production of sugpo is how to obtain a constant supply of fry. Since ultimately it is the private sector which should produce the sugpo fry to fill the needs of the industry, the Barangay Hatchery Project under the Prawn Program of the Aquaculture Department of SEAFDEC has scaled down the hatchery technology from large tanks to a level which can be adopted by the private sector, especially in the villages, with a minimum of financial and technical inputs. This guide to small-scale hatchery operations is expected to generate more enthusiasm among fish farmers interested in venturing into sugpo culture.

The manual provides information on the technology involved in induced maturation and broodstock of Penaeus monodon . Following background material on basic aspects of reproductive biology of the species such as mating, maturation, spawning and fecundity, a detailed discussion is presented on the broodstock tank and pen system and the ablation process.
