REVIEW: Conservation breeding of the tadpole shrimp Triops cancriformis in Britain

  • Ian Hughes


Triops cancriformis (Bosc 1801), a branchiopodcrustacean, is restricted to a single known site in the BritishIsles. The reasons for its rarity and decline in Britain are notfully understood. A captive population has been established and aTriops Conservation Group formed to co-ordinate the conservationof T. cancriformis and to research the reasons for its decline.Particular attention is given to reproductive biology, ecologyand in-situ conservation as these are important factors in bothaquarium husbandry and ex-situ conservation. The factors governing the hatchability of eggs are varied and complex but onceestablished in captivity, husbandry appears to present fewproblems. The objectives of the conservation project areoutlined.
