Distribution Of Familly Ariidae Resources In Semarang Gulf Water

Abstract

Familly Ariidae is a potential and important resource, but information on the distribution and quantity of Demersal  fish are relatively  scarce and limited,  especially  those at Semarang  Gulf Water. Since is no initial  data concerning  the existence offamily Ariidae resources. The method for data collection of this research was survey, with samples  collected  from Korowelang   ( Location  I),  Semarang ( Location  II), and Morodemak ( Location  Ill).   Each location  consists  of 5 depths, about ± 1m,

±5m,   ± 1Om,  : ±15m, and> 20m   Sampling   parameter using  Push Net in the depth about ±l m,

and Beam Trawl  in the depth of±  5m,  ± 1Om,  ± 15m, and > 20m.  The Size Beam is  2 x 0,6 m,

and Mesh Size of body and cod end each of 2,5m and 0,5 cm. Respectively,  the abundance  was analized using Swept area Method. Total Dernersal  fish found during  the research was 6.561   Ind,

the most abudance( Ind/  100 m  ) was from ± 1 5m.  The Distribution  of Demersal  fish tends to take

place randomly, and bigger variety found on most species. The biggest quantity  was found at about

± 15m below surface, while  the smallest  species and quantity  were found  at about ± 11 m and >20m below  surface
