5th International Symposium onCage Aquaculture in Asia Programme Guide

2015

Even though cage aquaculture has been widely practised in fresh and marine waters globally over the past five decades, water bodies in Asia remain underutilised. The widening gap between demand and supply for fishery products can be best met by placing a greater emphasis on cage culture. Ever since the first symposium on Cage Aquaculture in Asia held in 1999, the event provided a valuable platform for researchers and stakeholders to interact and discuss research outcomes, socioeconomic implications and environmental issues associated with cage based aquaculture. The 5 th International Symposium on Cage Aquaculture in Asia (CAA5) is being organised by the Asian Fisheries Society and the ICAR-Central Marine Fisheries Research Institute (CMFRI), in association with the Asian Fisheries Society Indian Branch, from the 25 th to 28 th of November 2015 at Kochi, India. The event will cover an array of topics related to cage culture under the broad headings of Marine Production Systems, Inland Production Systems, Breeding and Seed Production, Nutrition and Feed, Health and Environment Management and Economics, Livelihood and Policies. CAA5 will feature a Symposium Theme Lecture, Keynote addresses, lead talks and invited presentations from a galaxy of international experts in the field of aquaculture, as well as oral and poster presentations pertaining to recent advances and research activities in the field. We have received over 150 submissions and the best of those selected for the Symposium are summarised in this book of abstracts. On behalf of CAA5, I thank the researchers who shared the results of their hard work with us. We also express our gratitude to the speakers who accepted our invitation to share their valuable experiences and knowledge with us. It is hoped the information collected in this publication will prove useful to policy makers, researchers and aquaculturists in promoting sustainable cage based aquaculture activities in the Asian region.

Grow-out Culture of High Value Finfishes inCost-Effective Cages

2015

Capture fisheries is undergoing tremendous changes either due to increased fishing pressure or due to decrease in the production of certain groups due to fishery dependent or fishery independent factors. In spite of increasing effort the catch of almost all commercially important fin fishes and shell fishes is on the decline and results in severe resource depletion and unemployment. Fishermen community solely depending on fishing for their livelihood is facing an uncertain future. Decline in marine capture fishery also affects the availability of cheap protein for the masses and also affects the GDP growth of the country. It is estimated that the demand for fish will increase by 4% in developed countries and by 57% in developing countries. It is in this context cage farming of fin fishes and shell fishes assume importance as a means to increase fish production. Since cage farming is done in open waters were wave action and current takes care of the day to day maintenance of the cult...

Aquaculture with floating and submersible cage

Gianluigi Negroni

The caged aquaculture industry has grown rapidly in the last 20 years and is evolving in response to globalisation pressures and the growing demand for aquatic products. Rapid population growth, increasing wealth and urbanisation in developing countries are leading to major changes in the supply and demand for animal protein-both land and fish. There was an orientation towards the integration of cage farms horizontally and vertically with hatcheries and feed mills, and towards the development and use of more modern cage systems. In particular, the need for suitable sites has allowed access and expansion of aquaculture cages in new areas not yet used, such as lakes, water retention reservoirs, rivers and brackish marine waters, coastal marine and offshore-shore. We will consider the HDPE (High Density Polyethylene) cages that are currently very wide spreads. Although the origins of the use of cages for the containment and transport of fish for short periods were used almost two centuries ago in the Asian region, we can think of an earlier use in the indigenous practices of nomadic fishermen who live on boats on the Mekong Delta and Tonle Sap in Vietnam and Cambodia. The marine cage culture was pioneered in the 1970s, with the great development of salmonid breeding in Northern Europe and particularly in Norway. The farming systems where cages are used are very diversified, like the number of species bred. Rearing operations in traditional cages (typical of most Southeast Asian countries) consist of small cages and are in contrast to modern production operations of industrial cages for salmon and trout on a large scale in Northern Europe and the Americas (more than 50 metres diameter and 20 meters deep). The type and uses of different cages adapt to the environment and the economic objectives of the various environmental areas must adapt to the cages and related mooring equipment. The rapid growth and success of the salmonids farming industry is due to a combination of interrelated factors, including the development and use of easily replicable and cost-effective technology (including the production of the hatchery), access to large areas of suitable water, a good selection of species and market acceptability, possibility of large corporate investments and good national regulation of the aquaculture sector in cages. It is important to understand the challenges for cage culture development and in particular the need to minimise the rapidly growing potential environmental and the sector ecosystem impacts. Challenges of using aquaculture cages We have a number of general issues to consider when approaching the challenges of using aquaculture cages. It is important to consider the breeding system and the consequent real

Economic viability of cage fish farming in India

2020

The ICAR-Central Marine Fisheries Research Institute (CMFRI) is a premier research institute involved in marine fisheries and mariculture research in the past several decades. The institute has been instrumental in developing noteworthy technologies and policies aimed at augmenting fish production and livelihoods of coastal fisherfolk in the country. In view of the declining catches from the marine capture fisheries, the enormous potential of mariculture need to be tapped for achieving the blue revolution targets. CMFRI has made significant strides in developing and popularising mariculture technologies such as mussel and edible oyster farming, sea weed farming, seed production techniques for high value finfishes and marine ornamental fishes. Cage fish farming is an emerging aquaculture technology in the country developed and popularised by the institute. Development of hatchery technologies of high value finfishes, standardisation of culture protocols as well as successful frontlin...

Transition from low-value fish to compound feeds in marine cage farming in Asia

2012

This technical paper presents the findings of the FAO Regional Technical Cooperation Project TCP/RAS/3203 (D) 'Reducing the dependence on the utilization of trash fish/low-value fish as feed for aquaculture of marine finfish in the Asian Region,' which was implemented between 1 August 2008 and 31 July 2011 in China, Indonesia, Thailand and Viet Nam. It comprises the results of the project components, namely, farmers' participatory on-farm trials and a concurrent survey of farmers' perceptions concerning the use of two feed types and microcredit, environmental impact assessments of the use of both feed types, and a survey and analysis of the potential impacts of a change to pellet feeds on the livelihood prospects of fishers and suppliers of trash fish/low-value fish. An assessment of changes in the perceptions of farmers before and after the farm trials was undertaken, and a final regional stakeholders' workshop was conducted after the completion of all the proje...

Sea Cage Farming of Cobia -The black kingfish in India

2019

Cobia, Rachycentron canadum, commonly known as Black Kingfish, is a fast growing warm water marine fish with pinkish white flesh. It is considered as a promising candidate species for farming due to its fast growth rate, excellent meat attributes and easy adaptability to farming conditions. In the Indian scenario, it has the added advantage of being suitable for ecological aquaculture production linked to rural fishing villages along the long coast line. Envisaging the potential and prospects for cobia farming in India, captive broodstock development was first initiated during 2006 at the Mandapam Regional Centre of ICAR – Central Marine Fisheries Research Institute (CMFRI), Tamil Nadu, India. The first successful captive breeding and fingerling production of cobia was achieved in 2010 in India by the ICAR – CMFRI, Mandapam Regional Centre and since then, cobia fingerlings are being supplied to the entire coastal regions of the country for farming. Cobia fish is popularly known by t...
