Magnetic tool helps solve artemia challenge

July 17, 2020  By Hatchery International staff

INVE Aquaculture has launched new tools that to help farmers drive efficiency in hatcheries.

The SEP-ART Tools are a sustainable solution designed to maintain quality nauplii, reduce losses and ensure safety for workers and the environment, according to a release from INVE Aquaculture, a subsidiary of Benchmark.

Traditionally, Artemia nauplii are separated from cysts using a double sieve or a decapsulation method which can cause mortalities in the nauplii, quality issues and is often labor intensive. Decapsulation is also a chemical exothermic process resulting in the release of waste product and toxic gasses which can be a risk to the environment and operators. During the decapsulation process heat is also produced which can damage Artemia cysts.

The newly launched tools are based on the Artemia SEP-Art technology produced by INVE Aquaculture in 2008. The SEP-Art technology consists of cysts covered with iron particles which are attracted to magnets leaving nauplii in the solution.


Available in manual, semi-manual and fully automatic, the tools are tailored to all hatchery sizes.

“We have been working on this innovation over two years and are now very pleased to bring our new tools to the market,” Geert Rombaut, product portfolio manager, said in a statement. “We always work closely with our customers to understand their needs. Efficiency is an important part of any aquaculture production system and we hope that these tools will support the healthy growth of fish and shrimp and our customers businesses”.

The three new products – HandyMag, CystTM 2.0, and AutoMag – allow all hatcheries of all sizes to produce higher quality nauplii in a standardized and efficient way.
