Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh dan menentukan dosis penambahan Sargassum sp. ekstrak. pakan yang optimal untuk kinerja pertumbuhan benih Ikan Siam Patin ( Panganius hypopthalmus ). Hasil analisis ANOVA, penambahan senyawa bioaktif dari Sargassum sp. berpengaruh sangat nyata terhadap kinerja pertumbuhan ikan (Fhit>Ftab). Penambahan Sargassum sp. ekstrak dalam pakan dengan dosis 20 g/kg berpengaruh terhadap peningkatan performa pertumbuhan benih Ikan Siam Patin ( Panganius hypopthalmus ) yang lebih optimal dibandingkan perlakuan lainnya (0 g/kg, 10 g/kg, 15 g/kg ), yang ditunjukkan dengan peningkatan nilai persentase pertumbuhan panjang mutlak (6,7 cm), berat mutlak (114,33 g), SGR (2,85%), FCR (1,05%), EPP (95%), IHS (0,51 %), dan SR (100%) . Nilai kualitas air pada saat pemeliharaan ikan berada pada kisaran optimum meliputi suhu (26-28°C), pH (6,2-7,6), dan DO (5,3-7 mg/L).

Abstract

Addition of Sargassum sp. into feed as a feed supplement is one effort that can be done to increase fish growth and immunity. This research aims to determine the effect of adding bioactive compounds from Sargassum sp. extract in feed on the health picture of Siamese catfish through structural changes that occur in the intestines and liver. Fish observations were carried out for 40 days. The results obtained regarding the survival rate (SR) value of Siamese catfish seeds show that there is no difference or has the same percentage, namely 100%. The results of observations on the histopathology of intestinal organs analyzed in a comparative descriptive manner showed that Siamese catfish fry were fed with Sargassum sp. extract experienced damage than fish seeds fed without the addition of Sargassum sp. extract (control). The damage that occurs includes leukocyte infiltration (IfL), necrosis (Ne), goblet cell proliferation (Psg), hyperplasia (Hpl), and hemorrhage, with a damage score analyzed using the semiquantitative scoring method, namely 1. Damage to the liver, namely experiencing congestion in the blood vessels.
