ABSTRACT

Multiple criteria analysis (MCA) is a framework for ranking or scoring the

overall performance of decision options against multiple objectives (Che Dinh

Ly, 2009). This study applied the scientific basis of MCA combined with on-site

surveys to determine the sustainable and effective aquacultural model in

Northern Ca Mau Province. A number of typical aquacultural models proposed

by Ca Mau Department of Agriculture and Rural Development and Aquaculture

and Extension Center include: (i) Marble goby fish model; (ii) eel fish; (iii)

freshwater fish; and (iv) forest fish. The criteria system was built on the opinion

of three groups of managers in the field of aquaculture, specialized scientists and

farmers as a model. In Northern Ca Mau freshwater area, the MCA results and

on-site verification found that the Marble goby fish model was the most effective

aquacultural model and Eel fish model was the least effective.

1. INTRODUCTION

Ca Mau province, after more than 10 years of

implementing the restructuring of agricultural

production - fishing - forestry to fishing -

agriculture - forestry, value-generating products

has grown significantly; the amount of

agricultural goods has increasingly improved in

quality and quantity. In particular, the North

freshening region of Ca Mau province plays an

important role in providing food and staple food

in the province (Ca Mau Statistical Office, 2011).

In general, these results show agriculture of the

North freshening area of Ca Mau province are

positive developments. However, it cannot be said

that the process of agricultural development is

sustainable in this province. In fact, Ca Mau

province is faced with many difficulties and

challenges, including:

- Irrigation system, irrigation infield serving

agricultural production is incomplete. Besides,

intensive investment level of farmers in the

North region of Ca Mau is inadequate. Last

but not least, post-harvest losses are very large

(Duong Van Ni, 2008).

- The situation of global climate change and sea

level rise leading to natural hazards (storms,

floods, droughts, landslides) consecutively

occur with higher frequency and greater

destructive power (specially U Minh districts).

- Diseases of crops and livestock always are

potentially harmful to worrisome levels and

are costly in prevention and difficult to

completely stop (Do Quang Tien Vuong,

2001).

- Environmental soil and water pollution

adversely affect agricultural production and

human health and have a tendency to increase.

Currently, agricultural structure and rural

economy have shifted towards diversification and
