As part of the programme, Dubai Aquarium & Underwater Zoo expects to set scientific protocols in areas including the handling of Sand Tiger Sharks, sperm collection and its cryopreservation, ultrasound monitoring of female sharks and hormone analysis to assess their reproductive cycle
, the artificial insemination process and potential live birth of pups.
The sand sharkpopulation is facing vulnerabilities due to a slow reproductive cycle
and indiscriminate shark finning.
For example, in Marocco and Italy, the reproductive cycle
of the carpet shell clams were similar to that described in this study and comprised a spawning period from late spring to early autumn (Shafee & Daoudi 1991, Matias et al.

Animal studies indicate polybrominated diphenyl ethers (PBDEs) are endocrine disruptors, potentially affecting the role of thyroid hormones in regulating the reproductive cycle
The reproductive cycle
of sharks can be defined by how often a species breeds and consists of two periods.
