Hatchery and nursery

The Asian Institute of Technology (AIT) is launching a new Certificate programme on Sustainable Asian Aquaculture via the AARM Academic programme, for one semester beginning August 2017. This certificate programme is a combination of well-designed course work and hands-on experience in specialised areas (fish/shrimp hatchery or farming). The programme is useful for both students (with credit transfer) and for working professionals and entrepreneurs (without credits).

In this issue:

Inspiring story of aquaculture in Sikkim - a journey from conservation to farming; farming of scampi and tiger shrimp together - a case study from West Bengal; Labeo pangusia - a candidate for diversification of hill aquaculture; sustainability of an integrated livestock-fish-crop farming system as a small scale enterprise; sustainable coastal aquaculture in India; potential scope and prospects of domestic fish market in Chhattisgarh.

Labeo pangusia is a highly prized hill stream carp found mainly in the deeper pools of upland streams. Heavy fishing pressure has led to depletion of wild populations in recent years and the species is likely to become threatened if a conservation strategy is not developed. We report on an investigation into the reproductive biology of this species and on the result of successful induced breeding trials.

The fourth major international event on giant freshwater prawns was organised by the Asian Institute of Technology from 20-24 March 2007. The conference, organised by Salin Krishna and Michael New, built on a series of highly successful events that trace back to the very beginnings of the industry. The first conference, Giant Prawn 1980 brought together all those involved in freshwater prawn research and farming for the first time and set many priorities for future research and development.

Bangana dero is one of the most popular indigenous minor carps in the north eastern states of India, fetching triple the market prices of Indian major carps. B. dero is a bottom feeder and feeds on insect larvae, molluscs, algae, zooplankton and detritus. Over the last two decades the occurrence of wild juveniles of this fish in Indian rivers has fallen drastically. A protocol for induced breeding, larviculture, nursery rearing and growout including polyculture of B. dero is described.

In Nepal, low quality and seasonal access to fish seed is an important restriction on the development of the aquaculture sector. Commercialisation of fish farming cannot progress rapidly in the absence of critical inputs and a regular supply of quality fish seed is an integral requirement for the transition of fish farming from a subsistence activity to a commercial enterprise. Participatory market chain approaches are a key tool for the social and economic improvement of farmers and market participants.

The objectives of this project were to i) develop a guidebook in English on "Farmer-to-farmer extension approaches for small-scale aquaculture" and ii) to translate the developed guidebook into selected local dialects in Asia-Pacific and other regions (e.g. Africa). The project made use of the significant results from the JICA projects in Cambodia, Benin and other countries on farmer-to-farmer extension approaches on technology extension for small-scale farmers. The book is available in eleven languages (English, Arabic, Bahasa Indonesia, Burmese, French, Khmer, Loatian, Malay, Nepali, Thai and Vietnamese.

The objective of this manual was to provide basic guidelines for the hatchery production of Pa Phia (Labeo chrysophekadion) fingerlings. It includes information on managing and spawning broodstock, genetic guidelines, egg incubation, hatching larviculture and fry rearing. Although the guidelines were specifically developed for production of Pa Phia at government hatcheries in the Lao PDR, they may be applied to other, related, species and could be adopted and commercialised by the private sector hatcheries

This publication is the major output of a regional programme jointly implemented by FAO and NACA in 2015 to document and disseminate successful practices that contribute to the sustainable intensification of aquaculture in the Asia-Pacific region. Twelve practices are described that contribute to at least one of the following: Improved production and resource use efficiency (land, water, feed, energy); improved environmental benefits; strengthened economic viability and farmers' resilience; and improved social acceptance and equity.

Domestication in livestock industries is the process in which animal populations change in response to the artificial environments of farming production systems. Significant and widespread economic gains have been achieved through genetic improvements made through domestication and selective breeding of commercially farmed shrimp species, particularly Litopenaeus vannamei. Different policies on the translocation of shrimp genetic resources have influenced the approaches to shrimp domestication in different countries. The present paper examines the different approaches.

Tropical shrimp aquaculture is facing a disease crisis that may be propelled by an interaction between management practices that cause inbreeding, and the amplification by inbreeding of susceptibility to disease and other stresses. Broodstock accumulate inbreeding and lose genetic diversity when they experience bottlenecks or are chronically too small. The genetic lock is a practice that leads to inbreeding at farm level. Inbreeding may be amplifying the severity of diseases, including the major current threats.

The twelfth meeting of NACA’s Technical Advisory Committee (TAC) was held in the coastal town of Cha-am, Thailand from 9-12 March. The TAC meets every two years to review NACA’s rolling work programme and propose amendments to realign it with the current needs of member governments and to account for new and emerging issues. In proposing changes, the TAC prioritises issues of common concern to member governments where there are prospects for regional collaboration.

The consultation was funded by the Australian Centre for International Agricultural Research as part of the project Culture-based fisheries development in Lao PDR and Cambodia. The consultation provided the opportunity to discuss the outcomes of a series successful projects that have been implemented over the past decade in the Asian region.
