Monthly assessments of proteins, fatty acids and amino acids inArtemia franciscanacultivated in ‘Las Salinas de Hidalgo’, state of San Luis Potosí, Mexico

Abstract

This study presents the biochemical contents of Artemia biomass produced in a pond in ‘Las Salinas de Hidalgo’, State of San Luis Potosí, Mexico. The culture was realized over a period of 1 year in an 80 × 50 × 0.65 m (200 m3) pond. The feed consisted of a mixture of four micro algae. Samples of 1 kg of Artemia biomass (wet basis) were taken monthly and total protein, total lipid, amino acids and fatty acids were assessed. The contents of total protein and lipids showed a similar tendency from July to December (maintained values of about 300 mg g−1 for protein and 90 mg g−1 for lipids). With the exception of methionine and arginine, other seven indispensable amino acids were detected in the monthly samples, having similar values during the period from July to December. The most common fatty acids determined were the C16, C18, C18:1 and C18:3n6. Both, C20:4n6 and C20:5n3, were observed occasionally, but in high quantities. The use of the four micro algae as food for the Artemia cultured extensively, improved the biochemical composition and allows using this crustacean as feed for several species of aquatic organisms used for ornamental or human consumption.

“…Through bioaccumulation processes, Artemia can accumulate fatty acids in their gut, making it a perfect diet for the larviculture of fish and shrimp (Castro et al, 2009;Dhont & Sorgeloos, 2002;Zadehmohseni et al, 2020). However, the BFT developed in this study promises a major leap towards developing a cheap and nutritionally rich diet for Artemia.…”

“…This influences the resistance of the cultured organisms to infectious organisms including bacteria, viruses, fungi, and parasites (Trichet, 2010), leading to high survival rates.
