Guidebook on farmer-to-farmer extension approach for small-scale freshwater aquaculture

Published: 15/9/2016 | 1085 views

This guidebook was prepared as an offshoot of the International Symposium on Small-scale Freshwater Aquaculture Extension, which was held in Bangkok, Thailand in December 2013. This document will serve as a guide on how to implement farmer-to-farmer approaches on small-scale freshwater aquaculture extension, which was solely based on successful on-farm experiences mostly in freshwater aquaculture in Cambodia. Every subject in this guidebook can be modified depending on the existing local situation and condition where the extension programmes will be implemented. It is also hoped that this guidebook can be adapted to other small-scale aquaculture operations in the region (e.g. brackishwater and coastal aquaculture), especially in poor rural areas.

Author(s): Ingram, B.A., Chanthavong, K., Nanthalath, T., De Silva, S.S. | Published: 4/2/2016 | 1526 views

This manual provides basic guidelines for the hatchery production of Pa Phia (Labeo chrysophekadion) fingerlings. It provides information on managing and spawning broodstock, genetic guidelines, egg incubation, hatching larviculture and fry rearing. The manual draws on published information on Pa Phia; results of artificial propagation trials conducted on Pa Phia during two projects funded by the Australian Centre for International Agricultural Research and the experiences of technicians at two government hatcheries.

Feeding and feed management of Indian major carps in Andhra Pradesh, India

Author(s): Ramakrishna, R., Shipton, T.A., Hasan, M.R. | Published: 15/12/2013 | 3026 views

This technical paper reviews the aquaculture of Indian major carps with special reference to current feeding and feed management practices in Andhra Pradesh, India. The study is based on a survey of 106 farmers from four regions in Andhra Pradesh (Kolleru, Krishna, West Godavari, and Nellore). While the study primarily focused on the feed management practices associated with major carp production, management practices that are used under polyculture conditions with other species-groups were also assessed. The study revealed that mash feed was the most popular and widely used feed type. De-oiled rice bran was used as the principal feed ingredient, followed by groundnut cake, cottonseed cake and raw rice bran. The poor quality of the mash feed ingredients, especially the de-oiled rice bran, groundnut cake, and cottonseed cake was an important issue of concern to the farmers. Commercially manufactured pelleted feeds were used by 33 percent of the farmers to complement their mash feeds, with the majority choosing to use sinking pellets. Since 2007, there has been a marked increase in the use of commercial pellets, most notably for the large-scale production of the striped catfish. Grow-out farmers feeding mash feeds used variants of a bag feeding method known as rope and pole feeding. In the nursery and rearing ponds, the commonly used feed ingredients included groundnut cake, de-oiled rice bran and raw rice bran. The most common feeding practice was broadcast feeding. Constraints to Indian major carp production were identified, and research and development needs characterised.

Better-practice approaches for culture-based fisheries development in Asia [Vietnamese translation]

Published: 26/5/2008 | 3435 views
This is the Vietnamese translation of the book Better-practice approaches for culture-based fisheries development in Asia. It is also available for download in English and in Lao.

The primary objective of this manual is to provide guidelines for attaining better practices in culture-based fisheries, an emerging practice in rural areas in the Asian region. It deals will the principles of culture-based fishery practices, primarily based on relatively long-term experiences in Sri Lanka and Vietnam. It is not only targeted at researchers per se, but also at stakeholders at the grass root levels, as well as planners and policy developers, particularly those of Asian nations embarking on culture-based fisheries as a strategy to enhance fish food production in rural areas. As such, the manual does not deal with the dynamics and interactions of stocked populations. It deals with the gross factors that are applicable to improving fish yields and therefore revenue; and sustaining culture based fisheries as a development activity in the long-term. The manual addresses the constraints to culture-based fisheries development in the region, and provides guidelines on ways and means of overcoming such constraints.

This manual is the final compilation of the experiences in Sri Lanka and Vietnam, together with the discussions that occurred at the three workshops held in the three Asian countries in October 2005. The manual is divided into two parts:

Part 1 provides general information on what is called "better-practice approaches" to culture-based fisheries; and

Part 2 provides experiences from Sri Lanka and Vietnam and includes a marketing study.

The manual is aimed at a variety of readers, including farmers, extension workers and policy makers.

Guidelines for broodstock management, propagation and culture

Published: 7/1/2008 | 7084 views
Better management practices for captive breeding and culture of semah and empurau which encompass broodstock management, artificial propagation and related husbandry activities.

Tor tambroides and T. douronensis, locally referred to as semah and empurau, respectively, are high valued mahseer species, indigenous to Sarawak, East Malaysia, with an aquaculture potential and of conservational value. These two indigenous species live in headwaters of most major river systems of this state. These two species also occur in Peninsular Malaysia and are distributed throughout south-east Asia from Indonesia to southern China (Kottelat et al. 1993, Roberts 1999, Zhou and Cui 1996). Semah is the State Fish of Sarawak, and both species currently fetch a very high market price are of high cultural value. Juveniles of these two species are also increasingly sought after by the aquarium industry (Ng 2004).

The Government of Sarawak, recognising the importance of these two species, made an attempt to evaluate their aquaculture potential, including captive breeding using long-term pond-reared broodstock, commencing in the 1990s. However, limited success was achieved until the period 2002-2004 when, in an international collaboration, researchers from Australia and Sarawak were able to captive breed both species using hormone induction techniques on long-term, pond-reared broodstock.

The Project 'Artificial propagation of empurau, Tor tambroides and semah, Tor douronensis, two species of commercial and conservation value to Sarawak, Malaysia', commenced in April 2001, and was successfully carried out over a four- year period. The Project accomplished the primary objectives, and the most outstanding achievements were the success in the captive breeding of the semah and empurau, and the training of the Malaysian officers in adopting the techniques, as a routine, and the successes in the larval to fingerling rearing of the two species escaped/released on the genetic diversity of the wild counterparts. As such, a genetic management plan is needed to warrant longterm maintenance of genetic diversity of cultured stocks, as well as to minimise potential adverse effects on the genetic integrity of the wild populations.

The recent successful hatchery production of semah and empurau brought to the forefront problematic questions regarding sustainability of the aquaculture development and stock enhancement program of these two species. From an environmental point of view, aquaculture and stock enhancement could be counter-productive if not properly managed, especially with regard to the potential negative impacts of hatchery-produced seed.

In the above context an enhancement strategy for the long-term management of semah and empurau broodstock, and conservation of wild stocks, based on genetic findings will be discussed in this guidelines. In addition, the guidelines also incorporate best husbandry management practices to ensure a supply of physically and genetically healthy quality seed.
