Background

• The development and success of the Backyard Multispecies Hatchery System (BMHS)

• NACA in cooperation with Queensland Department of Primary Industries, and SEAFDEC AQD assembled an expert team to evaluate the economic and socio-economic aspects of small-scale hatcheries in Bali

• This research was funded by an APEC exchange (FWG 01/2001 Collaborative APEC Grouper Research and Development Network --administered by Agriculture, Fisheries and Forestry – Australia), NACA and by ACIAR (FIS/97/73 Improved hatchery and grow-out technology for grouper aquaculture in the Asia-Pacific region)

Objectives of the study

General objectives:

– Provide a basis for recommendations to the APEC/NACA grouper network on the potential for small-scale hatcheries to support the development of sustainable grouper aquaculture

Objectives of the studyEconomic objectives:

– Document economic structure of small-scale grouper hatcheries– Develop a bio-economic model– Provide a cost-benefit analysis tool to asses R & D options– Provide a decision tool for researchers

Social objectives:

– Describe the development of the private grouper hatcheries– Assess the benefits to small-scale farmers, and to the wider

community

Methods

Study Methods:– Duration: 2-18 March 2002– Study carried out in cooperation with GRIM staff

and resident JICA Mariculture Expert– Face-to-face interview of owners, staff of hatcheries

& nurseries, and brokers– 17 hatcheries, two brokers, and one live fish trader– A questionnaire was used for face-to-face interviews

The Development of Backyard Hatchery

• Started with the collaboration between GRIM and JICA from 1988, then followed by Multispecies Hatchery Project in 1994

• GRIM’s involvement in the ACIAR project FIS/97/73 Improved hatchery and grow-out technology for grouper aquaculture in the Asia-Pacific region in 1999

Backyard Hatchery for Milkfish

• Introduced in 1993• Initially pickup by GRIM’s staff in collaboration with

small farmers• There are two types of milkfish hatcheries in Bali:– Complete hatcheries

broodstock maintenance, maturation, spawning, live food culture, fry production and marketing

– Partial hatcheries (Backyard hatcheries)hatch fertilized eggs and rear larvae to selling size

Backyard Hatchery for Milkfish

Technology Transfer of Backyard Hatchery for Milkfish

• There are three main factors attributed to the success of technology transfer of backyard hatchery for milkfish by GRIM– The willingness of the GRIM staff to invest in milkfish

hatchery, thus shortening the period between technology verification/demonstration and adoption by target beneficiaries

– GRIM distributing fertilized eggs for free to backyard hatcheries until breakeven

– The availability of technical support from the GRIM staff who may be called upon for advice by small farmers

Transfer of the Seed Production Technology for Humpback Grouper

• GRIM developed seed production technology for humpback grouper in 1998

• In November 1999, GRIM successfully produced 54,000 humpback grouper fry with backyard hatchery prototype

• There were two modifications made from milkfish hatchery to humpback grouper hatchery:– Sand filter– Frequency of water exchange and tank bottom cleaning

• November 2000, two hatcheries were able to produce juveniles from the 3 hatcheries trials

Prototype of Backyard Grouper Hatchery System

From Humpback to Tiger Grouper

• The success of humpback grouper hatchery technology also being expanded to other grouper species

• Tiger grouper, started to be produced in April 2001• Farmers, students and other interested persons may come to

GRIM to get practical training on the seed production technology for humpback and tiger grouper

• GRIM also produce manuals on seed production in English and Bahasa Indonesian

Grouper Hatcheries & Nurseries

Socio-economic Impact of Milkfish Hatcheries in Bali

• Collection of wild milkfish fry was a source of livelihood• With the development of milkfish hatchery technology,

new sources of livelihood and employment opportunities were created

• Different stages of seed production engaged different groups of people

• Created short-term construction works• Fishermen used to catch ornamental fish with destructive

methods found employment in milkfish hatcheries• Women also employed for counting and packing fry

Socio-economic Impacts of Grouper Hatcheries in Bali

• Grouper fry industry in Bali created four distinct groups:– Eggs supply– Hatchery– Nursery– Brokers

• Most grouper hatcheries employ at least two workers• Women employed for size-grading

Various Groups Working in Backyard Hatchery System

Economic Analysis of Backyard Hatcheries

• Undertakes a microeconomic evaluation of the small-scale grouper hatcheries

• 11 farms out of 17 surveyed provided economic data

• Sufficient data collected to develop a discounted cash flow model

Methods for Economics Study• Data collection• Data analysis

– Discount cash flow analysis– Discounting reduces a time stream of costs or benefits to an

equivalent amount in today’s dollar• Profitability measures

– Equivalent annual return – measure of annual profit after deducting capital, operating and labour costs generated over the life of the project expressed in today’s dollar

– Internal Rate of Return (IRR)– Benefit-Cost Ratio– Payback period

Cost Structure Evaluation of Small Scale Hatcheries

• The cost structure look at, and evaluate, comparisons between the 11 farms– Capital expenditure and land– Fertilised eggs– Feeds– Labour– Operating expenses

• Fuels and oils• Repairs and maintenance• Electricity

– Marketing Systems, Packaging and Freight

Results of Economics Analysis

• Annual return (profit)– AU$ 6,312 (2 tanks) – AU$ 100,037 (12 tanks)

• Internal Rate of return (IRR)– 12% - 356%

• Benefit cost ration– 1.27:1 – 3.09:1

• Payback period– 7 farms had a payback period of 1 year– 1 farm exceeding 10 years

Results of Economics Analysis

• Fingerling output– 13,500 to 280,000

• Production cost– AUD 11,433 to AUD 179,187

• Cost per fingerling– AUD 0.25 to AUD 0.85

• Revenue per fingerling– AUD 0.40 to AUD 1.72

Strengths and Weakness of Grouper Hatcheries in Bali

• Simple and easy to operate• Relatively low cost• Flexibility – designed for culture of various marine finfish

species• Lacking of nursery – leave a gap between 3-4 cm and the

stocking size of 10 cm for cage culture• Sole fertilised eggs supply for humpback grouper is GRIM• Prevention and control of virus is weakness• Demands are not recurrent so hatcheries are price takers

Conclusion

• The potential for small-scale hatcheries to support the development of sustainable grouper aquaculture

• Research on the following areas are needed to support the sustainability of there systems:– Establishment of criteria to determine good quality seed– Development of price and market information systems to

match supply with demand– Development and pilot-testing of models of farmer-scientist

linkages that are appropriate to the socio-political context of each country

– Due to clustering of hatchery/nurseries, there is a need for development of carrying capacity models for coastal areas

Conclusion

• The main constrains to future expansion of grouper hatchery are:– Market demand– Grow out culture– Supply of operating components
