It represents an alternative solution to over-fishing and the disappearance of certain aquatic organisms that are sought-after due to the growing need for seafood.<\/span><\/strong><\/h5>\n<p>In 2018, global production from aquaculture (source: FAO) reached 82.1 million tonnes of aquatic animals, 32.4 million tonnes of aquatic algae and 26,000 tonnes of pearls and ornamental shellfish, bringing the total to an all-time high of 114.5 million tonnes.<\/p>\n<p>Despite worldwide progress in the field of marine aquaculture, this sector still has plenty of room for improvement (in terms of economic growth), but sometimes suffers from a poor image linked to the negative environmental impacts of aquaculture under the old production methods.<\/p>\n<p>This increase calls for production control of classic and emerging marine species at all stages of rearing, and in particular the critical initial phase: the larval stage. To meet demand for fish fry, crustacean post-larvae or shellfish spat, hatcheries need to optimise their production performance during this phase.<\/p>\n<\/div><\/section><\/div>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-kqmt9b-c93e1d57577791c4cd6816cdd4298e29\">\n.flex_column.av-kqmt9b-c93e1d57577791c4cd6816cdd4298e29{\nborder-radius:0px 0px 0px 0px;\npadding:0px 0px 0px 0px;\n}\n<\/style>\n<div  class='flex_column av-kqmt9b-c93e1d57577791c4cd6816cdd4298e29 av_one_half  avia-builder-el-5  el_after_av_one_half  el_before_av_textblock  flex_column_div av-zero-column-padding  column-top-margin'     ><section  class='av_textblock_section av-liy9sb5g-6ae2e5e177b980804e3f7fcd6f0fa685'   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><p><span style=\"color: #000000;\">Zooplankton and especially copepods are among the natural prey of fish larvae.
