The strength of this RAS is its flexibility, as each row can be combined or operated independently, enabling MARS run multiple trials of varying parameters, research methods and species simultaneously. Salinity, temperature, oxygen and nitrogenous wastes can be adjusted effectively to fit the specific needs of any project. This system can support trials with adult shrimp and fish (\u2264400g) of various species, but is specialized for whiteleg shrimp and salmonids. Each tank has highly programmable automatic feeders and is connected to solid material collectors, making this system ideal for growth trials with accurate feed intake measurements. A variety of other analytical methods including histology, gut microbiome, organ biopsies and more can also be effectively carried out.<\/p>\n<\/div><\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-group alignfull m_section_white has-background is-layout-flow wp-block-group-is-layout-flow\" style=\"background-color:#ffffff\">\n<div class=\"wp-block-media-text alignwide is-stacked-on-mobile is-image-fill\" style=\"grid-template-columns:38% auto\"><figure class=\"wp-block-media-text__media\" style=\"background-image:url(https:\/\/matis.is\/wp-content\/uploads\/IMG_5341-739x1024.jpg);background-position:50% 50%\"><img loading=\"lazy\" decoding=\"async\" width=\"739\" height=\"1024\" src=\"https:\/\/matis.is\/wp-content\/uploads\/IMG_5341-739x1024.jpg\" alt=\"\" class=\"wp-image-46034 size-full\" srcset=\"https:\/\/matis.is\/wp-content\/uploads\/IMG_5341-739x1024.jpg 739w, https:\/\/matis.is\/wp-content\/uploads\/IMG_5341-217x300.jpg 217w, https:\/\/matis.is\/wp-content\/uploads\/IMG_5341-768x1064.jpg 768w, https:\/\/matis.is\/wp-content\/uploads\/IMG_5341-1109x1536.jpg 1109w, https:\/\/matis.is\/wp-content\/uploads\/IMG_5341-1479x2048.jpg 1479w, https:\/\/matis.is\/wp-content\/uploads\/IMG_5341-9x12.jpg 9w, https:\/\/matis.is\/wp-content\/uploads\/IMG_5341-1200x1662.jpg 1200w, https:\/\/matis.is\/wp-content\/uploads\/IMG_5341.jpg 1535w\" sizes=\"auto, (max-width: 739px) 100vw, 739px\" \/><\/figure><div class=\"wp-block-media-text__content\">\n<h2 class=\"wp-block-heading\"><strong><strong><strong>The big system (RAS-600)<\/strong><\/strong><\/strong><\/h2>\n\n\n\n<p>RAS-2 consists of 24 all-green tanks, each with a capacity of 600 liters, for a total of 20 cubic meters of water in the whole system.
