Abstract The high production of Pacific white shrimp (Litopenaeus vannamei) in Pidie Jaya impacts water quality decline around the ponds due to aquaculture waste. This condition causes shrimp to be susceptible to diseases, one of which is white feces disease (WFD). The objective of the study is to determine the level of hepatopancreatic damage caused by WFD through histopathological performance. Four shrimp samples were taken randomly from two semi-intensive ponds in Meurah Dua District, Pidie Jaya Regency, Aceh, Indonesia. The results showed that the histopathology in the hepatopancreas was severely damaged. The damages include vacuolization, fat degeneration, and necrosis in ponds with higher ammonia concentrations. According to pH, temperature, salinity, and ammonia concentrations, ponds near residential areas were more polluted than ponds far from residential areas. This condition is projected by the more damaged histopathological obstruction of the shrimp’s hepatopancreas.

The effect of two concentrations of an aqueous extract of the San Pedro Daisy, (Lasianthaea podocephala Gray) roots was evaluated on the water quality, physiological condition and production parameters of the white Pacific shrimp, Litopenaeus vannamei (Boone), farmed under intensive laboratory conditions. Two treatments and a control were considered: T1 (1 mL of extract per aquarium), T2 (3 mL of the extract per aquarium) and C (control, 0 mL of the extract). No negative effects of the treatments on water quality parameters were observed, which ranged into acceptable limits and without significant differences (P < 0,05). Some of the production parameters such as final biomass and FCA were slightly better in the treatments using the extract. The concentration of haemolymph metabolites indicate that shrimp from treatments with the extract were under better conditions, suggested by the levels of protein and cholesterol in the muscle; moreover, the gene expression results suggest that the extract could have an immunostimulatory effect on shrimp. However, additional studies are required to evaluate the active ingredients of the root extract at the molecular level in order to have more information for the potential use of the plant.

Abstract This study aims to determine the effectiveness of supplementation of sodium (Na) alginate Sargassum sp. from Lampung waters to enhance the non-specific immune response and the resistence of Pacific white shrimp (Litopenaeus vannamei) against white spot disease. This study used a completely randomized design with 3 treatments, namely feeding without alginate supplementation (A) or control, dietary Na alginate Sargassum supplementation at a dose of 2.0 (B), and 4.0 g kg−1 feed (C), each with four replications, for 14 days. Hemolymph sampling was performed on days 0, 7 and 14 to observe the parameter of shrimp hematology included total haemocyte count (THC), phagocytocyte activity (PA), phagocytic index (PI), and total plasma protein (TPP). The hepatopancreas histology profile and water quality were observed at the end of treatment. Data were analyzed by Anova at 95% of confidence interval and continued with Duncan test. Result showedthat the supplementation of Na alginat from Sargassum sp. significantly enhance several shrimp immune response namely THC, PA, and TPP. Meanwhile, the histology of the hepatopancreas of both shrimp treatment and control showed not significantly effect on tissue damage. The water quality was still in normal condition during the treatment. The results of this study indicate that the application of Sargassum alginate supplementation at a dose of 2gr/kg of feed is the best treatment to enhance the immune response of Pacific white shrimp.
