“…The pacific white shrimp is considered to be one of the most important aquaculture species all over the world (Food and Agriculture Organization [FAO], 2010). There are many studies about the effects of individual macro-algae on growth performance and immune response in L. vannamei (Yu et al, 2016; Niu et al, 2018; Schleder et al, 2018). However, the comparison among different kinds of macro-algae on pacific white shrimp was not found.…”

The study was conducted to compare and evaluate effects of four different macro-algaes on growth, immune response, and intestinal microbiota of Litopenaeus vannamei. In the rearing trial 1, shrimp were fed five diets containing four sources of macro-algaes for 8 weeks, named D1 (without macro-algae), D2 (Porphyra haitanensis), D3 (Undaria pinnatifida), D4 (Saccharina japonica), and D5 (Gracilaria lemaneiformis), respectively. Growth performance of shrimp in D5 diet was significantly higher than that of shrimp fed the control and D4 diet (P < 0.05); however, there is no significant difference among D2, D3, and D5 diets (P > 0.05). Apparent digestibility coefficients of dry matter from the D2, D3, and D5 diets were significantly higher than that from the control and D4 diets (P < 0.05). Supplementary macro-algaes enhanced hepatopancreas immunity through positively increasing total antioxidant status (TAS) and prophenoloxidase activity (ProPO), as well as up-regulating the hepatopancreas RNA expression of ProPO and IκBα and down-regulating the expression of transforming growth factor β. Furthermore, dietary macro-algaes modified intestinal microbiota of L. vannamei, boosting the relative abundance of beneficial bacterial such as Bacteroidetes, Firmicutes, and Bacillaceae, and decreasing those detrimental bacterial such as Gammaproteobacteria and Vibrionaceae. In the white spot syndrome virus (WSSV) challenge trial, shrimps were injected for 6-day after the rearing trial. On the fourth day, shrimp death started to occur, and the mortality in D2, D3, and D5 diets was significantly lower than that in control and SJ diets during 4–6 challenged days (P < 0.05). Dietary macro-algaes ameliorated hepatopancreas damage in L. vannamei by increasing TAS and ProPO activities and decreasing SOD activity, inhibiting the lipid peroxidation (malondialdehyde), as well as regulating the immune-related genes expression. Taken together, dietary macro-algaes availably relieved enterohepatic oxidative damage by improving antioxidant ability and immunity and regulated intestinal microbiota in L. vannamei. These results indicated that G. lemaneiformis is the most suitable macro-algae and then followed by U. pinnatifida and P. haitanensis as the feed ingredient for L. vannamei.

“…Azad et al (2005) mengemukakan peningkatan pertumbuhan oleh polisakrida dimungkinkan oleh daya cerna nutrisi yang lebih baik melalui peningkatan aktivitas enzim pencernaan. Schleder et al (2018b), menegaskan dalam penelitiannya bahwa terjadi peningkatan aktivitas absolut enzim amilase dan lipase pada hepatopankreas udang vaname (L. vannamei) yang diberi pakan mengandung 0,5, 2 dan 4 % S. filipendula sehingga menghasilkan biomassa akhir yang tinggi dibandingkan dengan kontrol, masing-masing 12,99, 12,86 dan 13,26 g. Hasil penelitian yang dilakukan oleh Puspita et al (2017) diketahui bahan aktif yang terdapat dalam ekstrak sargassum hasil ekstraksi enzimatik berasal dari senyawa fenol, yaitu florotannin. Diduga kuat bahwa kandungan senyawa aktif tersebut memengaruhi aktivitas enzim pencernaan.…”

“…Corona et al (2016) menerangkan bahwa di bagian atas gastrointestinal, polifenol berperan sebagai substrat sejumlah enzim dan memengaruhi metabolisme oleh enzim glukosidase, enzim fase I (hidrolisis dan oksidasi) dan enzim fase II (konjugasi dan detoksifikasi) yang ditemukan baik di usus kecil atau hati. Selain itu, mekanisme peningkatan daya cerna udang yang disuplementasi ekstrak sargassum telah dijelaskan oleh Schleder et al (2018b), pengunaan rumput laut S. filipendula dan U. pinnatifida dalam pakan meningkatkan luas lapisan permukaan epitel usus udang dan memengaruhi penyerapan nutrisi. Hal ini diperkuat oleh Yu et al (2016), bahwa penambahan 2% biomassa G. lemaneiformis meningkatkan panjang mikrovili sel dari epitel usus penyerapan udang vaname.…”

Intensification of white shrimp (L. vannamei) cultivation causes accumulation of waste aquaculture in the water and environmental stress which causes pathogenic organisms to develop and attack aquaculture organisms, so that mass deaths occur. Various efforts have been made to overcome this through feed production by adding ingredient that can enhance the body's immune system, but also function as growth promoters. The material that has both functions is seaweed Sargassum sp. The aims of this study was to determine the addition effect of sargassum extract from enzymatic extraction on feed to the specific growth rate/SGR and feed convertion ratio/FCR of white shrimp (L. vannamei). These study was conducted by experimental method used a completely randomized design (CRD) with 3 treatments and 2 repetitions. The treatment was namely A (feed with the addition of sargassum extract 0 g/kg feed), B (feed with the addition of enzymatically protease sargassum extract 2 g/kg feed) and C (feed with the addition of enzymatically carbohydrase sargassum extract 2 g/kg feed). The results showed that the feed with the addition of sargassum extract from enzymatic extraction had a significant effect (P<0,05) on specific growth rate (SGR) and feed conversion ratio (FCR). Water quality of media is in the proper range for shrimp farming.

“…It has previously been reported that several benthic species of seaweeds and snails enhance not only shrimp growth [16,30] and feed efficiency [31], but also shrimp immunity, resistance to thermal stress, and the viral challenges of disease [32][33][34], and color [11,14,15,17] when benthic species were fed as supplementary feeds. Therefore, although only the productivity, feed efficiency, and profitability of giant tiger prawn were considered here, Chaetomorpha sp.…”

With the worldwide demand for tropical penaeid prawn increasing in recent decades, more research on shrimp culture methods is needed to enhance efficiency and profitability for shrimp farmers. The objective of this study was to develop a technique to boost the productivity, feed efficiency, and profitability of the giant tiger prawn (Penaeus monodon). To accomplish this, a novel culture setup was established in which two benthic organisms, a filamentous green alga (Chaetomorpha sp.) and a microsnail (Stenothyra sp.), were propagated together with P. monodon post-larvae during an early culture stage and then offered to shrimp as supplementary live feeds in intensive aquaculture ponds. For the experiment, shrimp post-larvae (density: approximately 33 individuals m-2) were cultured in outdoor concrete ponds (9 × 9 × 1.2 m) under either control (fed only artificial feed, n = 3) or experimental (fed artificial feed and benthic organisms, n = 3) conditions until they reached marketable size (15 weeks). Apparent green algae consumption was 6.81 kg (8.4% green alga to total feed consumption), whereas microsnail consumption was 1.96 kg (2.4% microsnail to total feed consumption). Compared with the control group of giant tiger prawn, the experimental group showed significantly higher productivity (total number of shrimp produced: 118%; total shrimp production: 133%), feed efficiency (feed conversion ratio of artificial shrimp feed: 89%), and profitability (shrimp sales: 139%; balance between shrimp sales and costs: 146%), while labor and financial costs were kept minimal. These results can be explained by the enhanced growth of shrimp at the early stages of culture. The techniques developed in this study will help to advance the efficiency of intensive aquaculture operations for giant tiger prawn and also improve profitability for shrimp farmers.
