This is us
Fischtechnik International is a manufacturer of fisheries accessories specializing in fish sorting machines for live fish of all species and sizes. The product portfolio, in addition to sorting machines, includes fish counters, fish pumps, dewaterers, scales, transport containers, pond outlets (Teichmönche) as well as fittings, hoses and pumps. In its own metal fabrication shop, the core competencies lie in the processing of aluminium and stainless steel; pond outlets are manufactured to customer dimensions from seawater-resistant aluminium and stainless steel. All machines are designed in 3D and laser-cut, and an engineering team implements custom solutions to customer requirements. The company is the technological successor of Fischtechnik Fredelsloh and can look back on more than 40 years of manufacturing tradition; over 3,000 fish sorting machines sold in more than 70 countries attest to its international reach, and spare parts are still supplied for older machines.
