- a. providing a cryopreservation device consisting of an outer tube, an inner tube having a volume less than 100 μL and adapted for fitting inside the outer tube, and two weight elements adapted for fitting in opposite ends of the outer tube, wherein the weight of the weight elements is larger than the buoyancy of the device in a liquid cryogenic agent,
- b. inserting a volume of semen from an aquatic species in the inner tube,
- c. sealing the inner tube,
- d. inserting the inner tube inside the outer tube,
- e. arranging the two weight elements inside the outer tube and outside the inner tube, wherein the two weight elements are arranged in opposite ends of the outer tube, and sealing the outer tube,
