PENGARUH PEMBERIAN PAKAN TAMBAHAN YANG BERBEDA TERHADAP PERTUMBUHAN LOBSTER AIR TAWAR (Cherax quadricarinatus)

Abstract

Freshwater lobster ( Cherax quadricarinatus ) is a group of crustaceans that live in freshwater. This lobster has a good potential to be cultivated. This research was carried out to investigate the use of supplementary feeding to grow out the freshwater lobster. The research design used completely randomized design consisting of 4 treatments and 3 repetitions, namely PL (control), PW (pellets and carrots), PK (pellets and potatoes) and PJ (pellets and white sweet potatoes). The freshwater lobster used in this study was 5-7cm in size and 6-8g in weight. The results of this study indicated that supplementary feeding affects the increase in the growth of freshwater lobster, where the weight gain, daily growth rate and weight growth percentage were (2.21 ± 0.06 ), (1.05 ± 0.03) and (34.40 ± 1.15) in PW treatment, respectively.The highest length gain was in the PJ treatment (0.44 ± 0.02). This study explained that carrot supplementary feed was the best combination to optimize the growth of freshwater lobster.
