Assisted in its organization and implementation, in close coordination with the RLCT staff who were considerably responsible for the conduct of the said course.

6. Training Course on Backyard Hatchery, RLCT.

Assisted in the organization and implementation of this course which is being held in nine batches at the Chachoengsao fisheries station of the department of fisheries, Thailand. At this date, two participants have already completed the four-week course and presently two participants from China are undergoing the course.

B. RESEARCH

1. Working Group Meetings

Assisted in the organization and conduct of the meetings of the three working groups, viz. Legal and Financial, Training and Research, which had been formed by the NACA Advisory Committee Meeting in 1985 for preparation for recommendations towards the setting up of the inter-governmental NACA; and prepared an extensive background paper to facilitate the work of the Research Working Group.

2. Research Project Proposals

Prepared draft project proposals on fish genetics and reproductive physiology, fish diseases, nutrition and feed formulation, as research components under NACA.

3. Secondment of junior Scientists Programme

Assisted in the implementation of the programme of secondment of junior scientists which was initiated by NACA in 1985 and being continued. The first batch of junior scientists to complete this programme consisted of seven scientists from the Philippines, Indonesia, Sri Lanka and Malaysia, all of them either from regional or national aquaculture centres linked to NACA. They conducted their research through their participation in multidisciplinary research activities of the Centre and produced excellent pieces of research work in their respective fields. They were given the opportunity to observe and participate as members of the team working at their Centre. The research work was reviewed.

The second batch of junior scientists to undergo this programme consists of five scientists from the Philippines, Indonesia, China and Bangladesh. Assisted in the placement of these fellows and presently, two of them have initiated their work at RLCT.

4. Research Work of Associate Expert: Macrobrachium Studies

Supervised the research programme of the Associate Expert assigned to NACA. The preliminary work which he finished focused on the differentiation of the sex of Macrobrachium rosenbergii. The sex differentiation was studied morphologically and histologically over a period of 145 days using a population of M. rosenbergii bred and reared in a laboratory. The study found that the gonad differentiation is not a uniform development within a population of Macrobrachium rosenbergii. of the same age. The fast growing prawn (0.062 cm/day) develop earlier testis and ovary than slow growing ones (0.022 cm/day).

Supervised two other related research projects of the Associate Expert; the first, studies on the culture of the freshwater prawn at various stocking size and density in ricefields; and the second, experiments on sex deviation in the giant freshwater prawn through application of steroid hormones, Queen Bee hormone and an androgenic gland hormone analogue. Preliminary results have been reported regarding these studies.

5. Regional Research on the Fish Ulcerative Syndrome

Assisted in the organization of the regional research on the fish ulcerative syndrome. Worked very closely with the regional coordinator on fish disease (from RLCT) and the consultant (Stirling University) on the implementation of the research programme. The disease has spread to other parts of Asia and the research programme includes a monitoring component. NACA also provides a support service in the case of widespread epidemic.

6. National Aquaculture Centres: Research Programmes

Assisted the Project Directors in the national aquaculture centres in Nepal and Bangladesh in drawing up adaptive research programmes in these countries. The research thrusts in Nepal were directed towards integrated farming systems and polyculture in undrainable ponds, seed production; and in Bangladesh, carp farming, and integrated farming.

RECOMMENDATIONS

1. Training

Incidentally, I happened to be the resource person in the mission which went to review the training courses at RLCP and thus I had the opportunity to know the first hand reaction of some of the past trainees of the Senior Aquaculturists Course and the Integrated Fish Farming Course; of RLCP administration, senior officials and the University of the Philippines in the Visayas. It appears that the broad-based training programme of senior aquaculturists which is highly cost-effective has been very valuable for the region and it needs to be continued. This has also been my own impression which I gathered during my duty travels in many countries. The NACA mechanism has been very effective in organizing such trainings as envisaged in the original Project Document.

During my visits to different countries in the region, I also have come across the trainees who have been trained in different short-term training programmes. It is heartening to see their involvement in the technology transfer. Thus it is recommended that such training for technology transfer needs to be continued on the regional level.

NACA promotional role needs to be intensified in organising the in-country training programmes for the extension officials and for the farmers as has been done by NACA in Bangladesh.

2. Research

  1. The secondment programme of junior scientists needs to be as far as possible made available to the national centre staff who could be able to go back to the centre and thus play a major role in the transfer of technology.

  2. NACA lead centres are intensifying research for intensive production of prawn, shrimp, carp, catfish, tilapia, seabass, grouper and seaweed and mollusc farming. NACA efforts in promoting the transfer of technology of such farming system through its various programmes have already started paying dividends in the region. Thus the ongoing programmes of transfer of technology need to be continued.

  3. While manpower development for the region through the regular and short-term training programmes are being continued to produce technical manpower to man the development projects and undertake transfer of technology properly, it is essential that the the existing technology should be upgraded through disciplinary and multidisciplinary research to support and elevate the existing technology to bring it more under human control. Much has already been discussed during the National Directors' Meeting and a five-year plan was discussed. However, focus needs to be given on feed development, health management research, soil and water management, and socio-economic aspects. It is essential that the well-established NACA linkage and mechanism be utilized to ensure the conduct of such research programme with uniform methodology. A preparatory short-term training course or workshop should precede the launching of the programme, as has already been done by NACA for socio-economics and fish disease research.

Nutritional Research

NACA may play a very crucial role in promoting regional research in the following fields.

1. Regional research on the nutritional value of natural feeds in nursery and grow-out systems of different commodities and their nutritional requirements, and the formulation of cost-effective supplementary feeds from locally available ingredients for different life history stages.

Though these investigations are site-specific in terms of commodity, resources, natural feed, ingredients particularly non-conventional feedstuff locally available for formulation of supplementary feed, yet the problem of researches in this field are common requiring similar approach and standard methods and nutritional assays.

2. Regional Research on Fish Health Management

Already, NACA has gone far ahead in organizing the regional research programme on the environment and ulcerative syndrome in fish. Further it is also organizing the Fish Disease Diagnostic Training Course. Thus, while it is essential to develop diagnostic procedures for diseases and health monitoring methods, preventions and immunoprophylaxis for control of diseases are needed to be investigated and incorporated into farming technology. Though most of the parameters may be site specific but the approach and methodology are the same. Study on regional basis would also offer the opportunity to gather an overall information and perspective of the health management problems and would produce valuable research results without much duplication of effort.

3. Controlled breeding and seed production

Considerable progress has been made in breeding technology of several cultured species. However, controlled reproduction of a number of commercially important species is not yet achieved, Percentage of success of induced breeding in carps and other fish remains highly variable. Failures are correlated, partly with the potency of the donor pituitary, unsuitable weather conditions or poor condition of the broodstock. Of these, condition of broodstock appears to be the key element of the success of induced breeding. Investigations are needed to know the hormonal level in the blood during prime condition and spawning, manipulation of factors for maturation, accelerating the sexual development to shorten the sexual cycle, increasing the number of eggs., etc. so as to have better control on the breeding of fish and also to increase the egg production potential. Knowledge of ecophysiological aspects of the breeding is essential so as to create most conducive condition for spawning. Similarly, packages of practices need to be upgraded to minimize the mortality rate of seed during nursery period. Regional approaches to tackle these problems would be highly realistic in view of the common problem and common commodity in many countries of the region.

4. Integrated fish-crop-livestock and sewage fed pond farming research

Studies undertaken in certain countries of the region have indicated that fish/crop/livestock farming has multiple advantages to the farmers in terms of maximum yield and diversified products from a minimum-sized area, efficient use of resources in terms of units of space and time, increase income spread throughout the year, better employment for the family and community and more self-sufficiency in the food supply. However, scentific research is required to know the production/integration efficiencies. Utilization of animal and plant wastes, their decomposition, pathogenic organisms in wastes and their transmission to fish and through fish to human beings, plant as well as animal waste treatment, release of nutrients, common diseases and method of treatments all need extensive and intensive research investigations to evolve suitable models for efficient integrated farming systems relevant to the region. These are well-understood objectives of RLCC and it is for the region to utilize properly the wealth of information already generated by NACA/RLCC.

Further, utilization of sewage for animal protein production through aquaculture has considerable relevance to this region. Already, thousands of hectares in certain countries of the region have sewage-fed fish farms. Package of practices needs to be upgraded by certain countries of the region for nursery, rearing and grow-out pond management for carp, prawn, and tilapia farming. However, while these need to be upgraded, it is essential that the existing technology should be known and adopted with proper modification in the region.

5. Marketing of aquaculture products

Advancement in culture technology without a potential market or without improvement in marketing infrastructure can glut the market and reduce market price and profitability of operation. Much attention has been focused on means of increasing production but marketing aspects have not been adequately researched. Research on marketing economics would facilitate the decision-making for individual farmers as well as policy makers at the national and regional levels.

6. Socio-economic studies of aquaculture development

An assessment of social net benefit through aquaculture is essential to show the multiple benefits derived through it as compared to other protein production systems. Thus, research on the socio-economics of aquaculture systems plays an important role in the development of aquaculture. It provides a basis, not only for the decision-making among farmers, but also for formulating aquaculture policies. Such studies are generally lacking in aquaculture; therefore, efficient management decisions cannot be properly made by farmers, commercial fish farmers and by development agencies.

7. Soil and water quality management

Freshwater ponds in the region are often rainfed undrainable, which limit their production at times considerably. Development of technically and erconomically feasible rehabilitation methods (drainage, silt removal, improved harvesting, minimizing water losses, etc.) would increase production without substantial new investments. Development of up-to-date designing and construction guidelines for new pond systems and their application would result in decreased construction costs, more efficient pond management and increased productivity. Use of unconventional energy resources for pumping and aeration would help adoption of more intensive farming methods in remote areas.

Brackishwater ponds are also very often traditional tidal-fed ponds with low productivity. In many cases they have been constructed on acid sulphate soils, which further limits their production. Development of reliable site selection criteria, designing and construction guidelines would facilitate construction of more efficient pond systems. Operation costs of pump-fed brackishwater pond systems could be considerably decreased by using the most efficient pumps with low head and high water volume, therefore comparative studies on the available pumps are also needed.

Cage, pen, and raceway culture is also expected to develop rapidly in the future; thus engineering aspects of site selection should be standardized. The use of locally available construction materials need further studies.

Hatchery development continues to be the most essential prerequisitye for aquaculture development in the region. There is a strong need to develop appropriate hatrchery designs for finfishes and shellfishes both for small scale and large scale operations. Water quality control should be given high priority in these designs.
