Seaweed meal as a protein source for the white shrimp Litopenaeus vannamei

Abstract

The rhodophytes Hypnea cervicornis and Cryptonemia crenulata are abundant along the Brazilian coastline and are rich in nutrients. They may therefore be used as a source of protein in shrimp diets. The aim of the present study was to test this hypothesis. The experiment was conducted in a laboratory, where 10-day-old post-larvae aged underwent 7 days of acclimation in a 1,000 L tank. They were then kept in plastic aquariums, each containing 10 L, and 20 larvae were fed daily (10% of biomass) in four equal portions with one of four diets (five repetitions of each) for a period of 45 days.

Natural Products and Aquaculture Development

“…The use of microalgae in aquaculture could be as  Live microalgae: indispensable for commercial rearing of larval and juvenile aquatic species  As supplement: enhances the nutritional value of formulated feeds-via vitamins, carotenoids, phytochemicals, and highly unsaturated fatty acids  As a potential alternative to fish meal and fish oils-valuable source of protein and energy  Microalgae pigments: carotenoids, lutein and zeaxanthin to augment natural skin colouration in fish Microalgae have potential use as a food source in aquaculture because of its nutritional value (da Silva and Barbosa, 2008). The content of lipids, proteins (amino acids), carbohydrates and vitamins of various microalgae species is one of the main reasons for considering these organisms as feed source for aquaculture animal.…”

Innovative protein sources in shrimp (Litopenaeus vannamei) feeding

“…Gutiérrez‐Leyva () has reported an improved SGR in L. vannamei feed for a diet with 10% inclusion of Macrocystis or Sargassum meals. FM replacement with Hypnea cervicornis and Cryptonemia crenulata in shrimp diets at different percentages (39%, 26% and 13%) has shown no significant differences between treatments and control diet in terms of final biomass, biomass gain and SGRs (da Silva & Barbosa ). Similarly, the FCR improves with higher algae content: the inclusion of Hypnea cervicornis and Cryptonemia crenulata meals at high levels has exhibited better feed conversion than diets with lower contents (da Silva & Barbosa ).…”

Antioxidant activity and apparent digestibility of amino acids of three macroalgae meals in the diets of Pacific white shrimp (Litopenaeus vannamei)

“…In general, the use of macroalgae as an ingredient in diets for L. vannamei has not been observed to affect negatively the survival (Peñaflorida & Golez, 1996; Cruz- Suárez et al, 2000;Gutiérrez-Leyva, 2006;Da Silva & Barbosa, 2008;Peña-Rodríguez et al, 2010).…”
