Striped catfish (Pangasianodon hypophthalmus) farming in the Mekong Delta, Vietnam, is considered as a major, aquaculture development both in Vietnam and globally. One of the main drivers responsible for the explosive growth of the sector is considered to be the development and commercialisation of techniques for artificial propagation of the species. This chapter looks first at the life-cycle of the striped catfish and historical developments in hatchery technology before going on to discuss induced breeding of catfish in hatcheries together with larval and fry nursing. Finally, harvesting and transportation are described and possible future directions in the sector.

Aquaculture is the fastest-growing food production sector in the world. With demand for seafood increasing at astonishing rates, the optimization of production methods is vital. One of the primary restrictions to continued growth is the supply of juveniles from hatcheries. Addressing these constraints, Advances in aquaculture hatchery technology provides a comprehensive, systematic guide to the use of current and emerging technologies in enhancing hatchery production.Part one reviews reproduction and larval rearing. Aquaculture hatchery water supply and treatment systems, principles of finfish broodstock management, genome preservation, and varied aspects of nutrition and feeding are discussed in addition to larval health management and microbial management for bacterial pathogen control. Closing the life-cycle and overcoming challenges in hatchery production for selected invertebrate species are the focus of part two, and advances in hatchery technology for spiny lobsters, shrimp, blue mussel, sea cucumbers and cephalopods are all discussed. Part three concentrates on challenges and successes in closing the life-cycle and hatchery production for selected fish species, including tuna, striped catfish, meagre, and yellowtail kingfish. Finally, part four explores aquaculture hatcheries for conservation and education.With its distinguished editors and international team of expert contributors, Advances in aquaculture hatchery technology is an authoritative review of the field for hatchery operators, scientists, marine conservators and educators. - Provides a comprehensive guide to the use of technologies in enhancing hatchery production - Examines reproduction and larval rearing, including genetic improvement and microdiets - Discusses challenges in hatchery production of specific species

Good water quality is of major importance to production results in a hatchery, particularly in those which work more intensively. A low cost water transfer system is also important economically, affecting both investment and running costs. The low cost, however, should not be allowed to compromise the efficacy of the system, leading to operating problems or a lower water quality, for example. This chapter will take a brief look at some important factors in the location of hatcheries, before progressing to assess different water supply systems, encompassing both fresh water and sea water. Before the water entersthe production unit, it hasto be treated to fulfill the requirement of the aquatic organism as closely as possible. A description of different water treatment equipment/methods is also included in the chapter.

This chapter provides an update on the most common zooplankton live feed species used in hatchery rearing of fish and shellfish larvae, namely rotifers, Artemia and copepods. Each section starts with a summary of the biology and ecology of these species. An overview of the most common techniques to culture, feed, harvest, disinfect and preserve these organisms is provided. Special attention is given to nutritional and microbiological aspects. Furthermore, new trends and developments are discussed.

Microalgae remain an indispensible hatchery food for many aquaculture species, despite some on-going progress in the development of formulated larval feeds. The majority of the microalgae feed production occurs as living cultures on-site within hatcheries. In this review, general characteristics of microalgae are discussed, including chemical profiles, nutritional qualities and methods of mass culture. Key microalgal species are identified that are used as feeds leading to the hatchery production of bivalves, abalone, shrimp and fish. Global demand for microalgae production as hatchery feeds is likely to increase, requiring not only the expansion of existing infrastructure, but technical innovation to develop new production systems that are more intensive and have greater production capacity.

In aquaculture production systems, the hatchery phase is the most challenging as larvae are prone to infections and disease from microbial agents causing mass mortalities. A holistic microbial management regime concept is developed with the hatchery managed as a set of compartments: (1) the water column (planktonic); (2) surfaces (biofilm); (3) the larvae themselves; and (4) feeds (live and formulated). Emphasis on the use of the microbial community as a whole to maintain larvae in high health with various prophylactic strategies is discussed. A range of treatment strategies are considered, including antibiotics, bacteriophage therapy, quorum sensing inhibition and microbial predation. Developing innovations and future trends in microbial management and biocontrol are outlined.

This chapter looks at the issues surrounding health of finfish and shellfish larvae in the aquaculture environment. The chapter will examine issues such as biosecurity to see how it forms the cornerstone of effective hatchery management and how problems can arise when biosecurity fails. Then the chapter looks at how the health of the larvae can be manipulated and how the larvae can be protected from potential pathogens by good management.

This chapter deals with the different methods used in the world to produce hatchery-reared juveniles of Octopus vulgaris, including capture and transport methods, broodstock conditioning and paralarval rearing technology. First, a review is made of the different systems used for hatchery production of the various Cephalopod species in which there is the greatest commercial interest. Then, specifically for Octopus vulgaris, conclusions and standardized methods related to the spawning process, the control of embryonic development and, finally, a protocol for paralarval rearing are also given. The main bottlenecks and future research trends are pointed out, and important sources of further information and advice are referenced. A brief review of the state-of-the-art on larvae and juvenile rearing of other cephalopods species is also included in this chapter.

In this chapter the benefits of short- to long-term storage of genetic material from aquatic species in liquid nitrogen are introduced. The biophysical and chemical challenges that arise during freeze-thawing are presented from the perspective of the large degree of structural and biological diversity found in fish, mollusc and crustacean gametes. Sperm cryopreservation procedures and the challenges raised by cryopreservation of oocytes and embryos or larvae are then discussed with a special focus on the importance of the genetic integrity of the thawed cells. Alternatives to the cryobanking of gametes and embryos rely on the cryopreservation of cells of somatic, embryonic and germinal origin. The challenges posed by the use of such cells to reconstruct fish are then described.
