Pelagic fishes are important fisheries resources in the South China Sea Area. The aim
of the study is to determine the dynamics and status of pelagic fishes and develop the
fishery management efforts for sustainable development in the region Three
analytical methods, correlation analysis, principal component analysis and cluster
-:analysis were used for this purpose. In this study, 19 species groups were considered
and annual catch data were collected from SEAFDEC Fishery Statistical Bul1etins
from 1976 to 1996. For estimation of MSY (Maximum Sustainable Yield) in the
East Coast of Peninsular Malaysia, Schaefer's Surplus Production Model was used
based on catch and effort data.
In the case study of estimation of MSY, the estimated MSY was 94,321 mt
and fMSY was 74,011 (days/year) by fishing gear standardization. This study estimated MSY-like value of the whole South China Sea provisionally based on
studies done in the East Coast of Peninsular Malaysia.
The correlation analysis showed the relationship among 21 sub-areas on the
basis of catch composition per year .The study indicated that Taiwan, Hong Kong
and Singapore did not show significant relationship with other sub-areas. However,
West Sumatra, South Java etc showed significant relationship with other sub-areas.
The principal component analysis showed alternation of the major species
groups in different sub-areas. The analysis indicated that alternation of major catches
..
were observed at two or four years interval while some species groups were found to
be stable over the periods in different sub-areas. Alternation of pelagics by sub-area
and by species are very important information as the baseline data for multicountry's
fisheries management.
The cluster analysis was used for grouping of sub-areas on annual basis and
overall basis. The results of overall basis are summarized in the following two types
of grouping. The first type of grouping is as follows: (1) Taiwan, Indonesian part of
Malacca Straits, West Coast of Peninsular Malaysia, East Sumatra and Kalimantan;
(2) Luzon, Visayas, Mindanao, Sulewesi & Gulf of Thailand; (3) Hong Kong, West
Sumatra, North java, South Java, Bali-Nusa Tenggara, Maluku-Irian Jaya, East
Coast of Peninsular Malaysia, Sarawak, Sabah, Indian Ocean and Singapore. The
second grouping is that, all sub-areas were grouped into six clusters: (1) Taiwan;(2)
Gulf of Thailand; (3) East Coast of Peninsular Malaysia & North Java; (4) Indonesian part of Malacca Straits, West Coast of Peninsular Malaysia; East Sumatra
& Kalimantan; (5) Luzon, Visayas, Mindanao & Sulawesi and (6) Hong Kong, West
Sumatra, South Java, Bali-Nusa Tenggara, Maluku-Irian Jaya, Sarawak, Sabah,
Indian Ocean & Singapore.
On the pelagic resources or shared stocks, this study emphasized the
importance of multi-country's fisheries management and that detailed information is
required to achieve the objectives. This study identified the fisheries relationships
among the sub-areas, and also clarified the alternation of pelagics in the South China
Sea area, based on the multivariate analyses. The important baseline information
obtained from the study can be utilised for multi country's pelagic fisheries
management in the South China Sea area. |
