Analysis of affecting factors of Vannamei shrimp (Litopeaneus Vannamei) production farming

Abstract

Shrimp is one of commodity that has a great demand by consumers both domestically and abroad as an export commodity. There are 2 types of shrimp that are cultivated in North Sumatra, namely Vannamei shrimp and tiger prawns. Cultivation of Vannamei shrimp has grown rapidly, replacing tiger prawns’ cultivation. The objective of the study is to analyse the affecting production factors for cultivating Vannamei shrimp. The research location was determined purposively in Medang Deras District, as it is one of the production centres for Vannamei shrimp. The entire population in the study area was sampled (using the census method). The multiple linear regression analysis method is used to analyse the data that has been collected through a survey using a questionnaire. The results showed that simultaneously, the feed amount, fry number, medicine amount and lime amount significantly affected the production. And partially, the feed amount, medicine amount and lime amount also significantly affected the production, while the fry number insignificantly affected the Vannamei shrimp production. The food amount significantly affected the production with the greatest coefficient value. The lime application at the research location was crucial because it negatively affected the Vannamei shrimp production.
