- You may be looking for the Kyrian named Quarren.
Their ships used warp technology and tractor beams, the Quarren also used subspace mines. Quarren systems required a high level of supervision and involved little automation, which was unique for a warp capable species. The Quarren made use of a multi-species workforce. Some workers were acquired by less scrupulous employers through abduction because their homeworld suffered from a severe manpower shortage. They made use of memory alteration to make their captured workers more productive and less likely to escape. (VOY: "Workforce", "Workforce, Part II")
