In the last 10 years, experiments with Atlantic salmon, rainbow trout, char, tilapia and white-tailed prawns have been successful.<\/p>\n\n\n\n<p>The RAS systems are becoming increasingly important in the aquaculture sector and these facilities also provide an opportunity for research to further improve their utilization.<\/p>\n<\/div><\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-group alignfull m_section_white is-layout-flow wp-block-group-is-layout-flow\" style=\"padding-top:0;padding-right:0;padding-bottom:0;padding-left:0\">\n<div class=\"wp-block-media-text alignwide has-media-on-the-right is-stacked-on-mobile is-image-fill-element\" style=\"grid-template-columns:auto 30%\"><div class=\"wp-block-media-text__content\">\n<h2 class=\"wp-block-heading\" id=\"bunadur\"><strong><strong>The small system (RAS-200)<\/strong><\/strong><\/h2>\n\n\n\n<p>The most experienced system in MARS is the RAS-200, operated since early 2019. It consists of 36 black tanks with a white bottom, each 200 liters in volume, for a total of 8.5 cubic meters of water in the entire system. The strength of this RAS system is its flexibility, as each series can be controlled independently or combined with others, allowing MARS to run multiple experiments on different variables, research methods and types simultaneously. Salinity, temperature, oxygen and nitrogen waste can be adjusted effectively to suit the specific needs of each project. This system can support testing of adult shrimp and fish (\u2264400 g) of various species but is specialized for white-tailed shrimp and salmonids. Each tank has programmable automatic feeders and is connected to a solid collection device, making this system ideal for growth experiments with accurate feed intake measurements. Various other diagnoses can also be performed, including histology, intestinal microorganisms, organ samples and more.<\/p>\n<\/div><figure class=\"wp-block-media-text__media\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/matis.is\/wp-content\/uploads\/IMG_5216-1024x683.jpg\" alt=\"\" class=\"wp-image-46027 size-full\" style=\"object-position:50% 50%\" srcset=\"https:\/\/matis.is\/wp-content\/uploads\/IMG_5216-1024x683.jpg 1024w, https:\/\/matis.is\/wp-content\/uploads\/IMG_5216-300x200.jpg 300w, https:\/\/matis.is\/wp-content\/uploads\/IMG_5216-768x512.jpg 768w, https:\/\/matis.is\/wp-content\/uploads\/IMG_5216-1536x1024.jpg 1536w, https:\/\/matis.is\/wp-content\/uploads\/IMG_5216-2048x1366.jpg 2048w, https:\/\/matis.is\/wp-content\/uploads\/IMG_5216-18x12.jpg 18w, https:\/\/matis.is\/wp-content\/uploads\/IMG_5216-1200x800.jpg 1200w, https:\/\/matis.is\/wp-content\/uploads\/IMG_5216-1980x1320.jpg 1980w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure><\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-group alignfull m_section_white is-layout-flow wp-block-group-is-layout-flow\" style=\"padding-top:0;padding-right:0;padding-bottom:0;padding-left:0\">\n<div class=\"wp-block-media-text alignwide is-stacked-on-mobile is-image-fill-element\" style=\"grid-template-columns:38% auto\"><figure class=\"wp-block-media-text__media\"><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\" style=\"object-position:50% 50%\" 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><strong>The large system (RAS-600)<\/strong><\/strong><\/strong><\/strong><\/h2>\n\n\n\n<p>The RAS-600 consists of 24 green tanks, each with a capacity of 600 liters, for a total of 20 cubic meters of water in the entire system.

The temperature and salinity of the system can also be largely controlled here, but this RAS is usually maintained at 33ppt and ~ 10 \u00b0 C, as it is ideal for simulating the marine environment for large fish. Each tank is also equipped with an automatic belt feeder and connected to a solid collection system that can be used as a feed collector for non-eaten feed.
