Calcium-Rich Natural Feed and Its Effect on Average Daily Gain, Survival Rate, and Histopathology of Hepatopancreas and Intestine in Green Lobster (Panulirus homarus)

Research High-Calcium Natural Feed on Average Daily Gain, Survival Rate and Histopathogical Hepatopancreas and Intestine of Green Lobster (Panulirus Homarus) few have done so, even though this is important to observe and know. The aim is to find the food habit of green lobster, so that this information can be known to stake holders and can be a consideration when cultivating.  The research was conducted from August 2024 to November 2024 at Padjadjaran University Marine Station in Pangandaran Regency. Aquaculture research has been conducted with 4 treatments namely A (80% anchovy feeding), B (100% anchovy feeding), C (80% rebon feeding) and D (100% anchovy feeding), repeated 3 times. Parameters observed were Average Daily Gain (ADG), Survival Rate (SR), histopathological hepatopancreas and lobster intestine.  ADG and SR were reported quantitatively, while histopaptologic was reported descriptively. This study was conducted using a completely randomized design (CRD) and the results showed that lobsters fed with 100% anchovy feed (D) showed a high ADG of 1.63. which was different from lobsters fed with 80% anchovy feed (A), lobsters fed with 80% rebon feed (C) and 100% (D).  This Calcium-rich feed gives a high SR and is equally good at 96% in treatments A, B, C and D. Histopathology of the hepatopancreas shows a healthy lobster condition.
