Utilization of idle ponds for semi intensive vannamei (Litopenaeus vannamei) cultivation integrated with red tilapia (Oreochromis niloticus), seaweed (Gracilaria verrucosa), and oysters (Crassostrea sp) in Mamuju, west Sulawesi
Abstract
Shrimp farming failure is frequently constrained by low farm productivity. This is dueto
a variety of issues, including high soil acidity, a lack of soil nutrients, high pyrite, iron levels,and
organic matter. In general, alluvial ponds with low soil productivity predominate in coastalareas.
As a result, shrimp farming in alluvial ponds necessitates careful management. The purpose of
this research was to determine the effect of vannamei stocking density in conjunctionwith red
tilapia, seaweed, and mangrove oysters on vannamei production. The studywas carriedout in
Mamuju, West Sulawesi. The treatments in this study were differences in vannamei shrimp
stocking density that were managed semi-intensively; specifically, A was 220,500 individuals per
pond (60 individuals per m2) and B was 118,500 individuals per pond (30 individuals per m2).
Each pond was also stocked with 2,200 red tilapia per pond, and biofilters such as seaweed and
mangrove oysters were used. The study's findings revealed that in A, the survival rate and
production of vannamei and red tilapia were 61.39±2.426 % (1,554±2.08 kg per pond) and
63.86±4.638 % (274.57±37.188 kg per pond), respectively, and in B, the survival rate and
production of vannamei and red tilapia were 68.83±8.867% (957.56±67.660 kg per pond) and
253.28±33.372 kg per pond with a survival rate of 59.60±607.071%.
