PERKEMBANGAN LARVA UDANG GALAH (MACROBRACHIUM ROSENBERGII) HASIL PERSILANGAN POPULASI ACEH DAN STRAIN SIRATU

Abstract

Giant freshwater shrimp culture were very interested and booming because it has economic values. The problems of control over the genetic qualities giant freshwater shrimp will fall especially on the promotion of production management larvae without followed a good parent, efforts to be carried out is to genetic improvement through the activities of a cross parent (hybridization) in order to produce larvae with a superior quality. Intraspecifik hybridization use giant freshwater shrimp, Aceh population (A) and Siratu strain (R) should be conducted in resiprokal (RA and RA) and pure line (RR and AA). This study aims to assess a cross resiprokal percent Giant freshwater shrimp of the aceh population and siratu strain against the rate and duration of the development larvae of which produced.The result of research show that the larvae of crossbreeding with a method of hybrid resiprokal Siratu x Aceh (RA) with a value of growth rate up 9,87 and duration of the development of 27 day has better effort than hybrid AcehSiratu (AR) with a value of growth rate up 9,78 and duration of the development of 30 day in order to achieve post larvae. The results of a cross hybridization RA and AR longer than inbrida Siratu x Siratu (RR) but faster compared to inbrida Aceh Aceh x (AA) as an elder.
