Sargassum sp. is a natural ingredient that can be used to improve the health status of fish. This study aims to test the extract concentration of Sargassum sp. which is mixed into commercial feed against the hematological profile of star pomfret. This research was conducted in September - November 2020. The process of extraction and toxicity tests was carried out at the Marine Chemistry Laboratory FIKP, then in-vivo tests were carried out in Madong Village, Kampung Bugis Village. The fish blood profiles were analyzed at the Marine Biotechnology Laboratory FIKP. The research method used was experimental using a completely randomized design (CRD) with 4 treatments and 3 replications, namely control (0 ppm extract of Sargassum sp. + feed), treatment A (38 ppm extract of Sargassum sp. + feed), treatment B (58 ppm extract of Sargassum sp. + feed), and treatment C (78 ppm extract of Sargassum sp. + feed). The results showed that the highest hematocrit value was 54.65%, the highest lymphocyte percentage was 87.67%, the highest monocyte percentage was 6.00%, and the highest neutrophil percentage was 7.33%. Provision of SargassumExtract sp.. at a dose of 58 ppm through commercial feed has an effect on the hematocrit value and the percentage of lymphocytes but does not have an effect on the percentage of monocytes and neutrophils in pomfret fish

Maintenance was carried out for 23 days at HSRT Maju Mandiri Madong Village, Tanjungpinang City, Riau Islands Province. The production of banana peel extract takes place at the Marine Chemistry Laboratory of the Faculty of Marine and Fisheries Sciences, Raja Ali Haji Maritime University. This research was conducted experimentally by testing the extract of the banana peel of the white snapper. This study was designed using a completely randomized design (CRD) with 4 treatments (0 ppm, 0.5 ppm, 0.9 ppm, and 1.3 ppm) 3 replications. The results of this study showed that Kepok banana peel extract had a significant effect on the percentage of lymphocytes, neutrophils and hematocrit values â€‹â€‹but had no significant effect on the growth and survival of white snapper fry. The use of Kepok banana peel extract mixed in the feed has a significant effect on the leucocyte differential, namely the percentage of lymphocytes and neutrophils in the white snapper fry. The best percentage of lymphocytes and neutrophils was in treatment C, with values â€‹â€‹of 75.67% and 12.33% in white snapper fry.
