Abstract Dietary supplementation with seaweeds has the potential to improve the immune response and physiological performance of marine shrimp under stressful conditions. This work evaluated the effect of dietary supplementation using different ratios of the brown seaweeds Sargassum filipendula (S) and Undaria pinnatifida (U) on the gut microbiota as well as on the resistance to thermal shock and White Spot Syndrome Virus (WSSV) of Litopenaeus vannamei. Additionally, hemocyte lipid and protein p...

In 1998 Critchley and Ohno published the book Seaweed resources of the world presenting a synthesis of knowledge on the subject from different regions and countries globally. One chapter by E.C. Oliveira was focused on Brazil. In this article, we present an update of the economically relevant species of Brazilian seaweeds, and their distribution along the coastline, and what has changed over 20 years in the status of the exploited resources, the new species with commercial potential, and relevan...

Abstract This work aimed to evaluate growth performance, gut histology, digestive enzyme activity and resistance to challenge with White Spot Syndrome Virus (WSSV) of Litopenaeus vannamei fed 0.5, 2 and 4% of dry biomass from the brown seaweeds Sargassum filipendula and Undaria pinnatifida. Shrimp (4.23 ± 0.15 g) were reared for 38 days in 800 L tanks (40 animals per tank) in triplicate under constant aeration (O2 > 5 mg L−1), controlled temperature (29.06 ± 0.32 °C) and 100% daily water exchang...

Abstract - A new flotaton model for the experimental culture of macroalgae Kappaphycus alvarezii (Doty) Doty ex P.C. Silva is described and illustrated. The ellipsis-shaped 90L apparatus is made of medium density virgin polyethylene, measuring 2000mm long x 300mm wide x 200mm high, and weighing 9kg. The device has been successfully tested in the litoral region of the state of Santa Catarina, Brazil, throughout the experimental period. Contrastingly to traditional models available on the market, w...

Abstract Pacific white shrimp, Litopenaeus vannamei , is a tropical species known to be intolerant to cold. In our earlier work, increased thermal shock resistance caused by Sargassum filipendula raised unanswered questions about the mechanisms responsible for this resistance. Therefore, in the present work, we used MALDI-TOF mass spectrometry (MS) to assess protein and lipid profiles of intact and lysed hemocytes from Pacific white shrimp fed 0.5% of S . filipendula and submitted to thermal sho...

Abstract The growth and metabolic profile of the red seaweed Kappaphycus alvarezii were evaluated after in vitro cultivation with effluents from Pacific shrimp Litopenaeus vannamei farming in bioflocs system (BFT) and commercial extract of the brown seaweed Ascophyllum nodosum (AMPEP). Seaweeds were cultivated for 35 days in sterilized seawater enriched with 50% von Stosch solution (VS – v/v), 25% BFT effluent (BFT – v/v), or pulse-fed AMPEP (at 0.1 g L − 1 for 30 min), and combinations of VS an...
