The Deep Sea Fishing Authority has a Data base, this Data base is used to store, process and analyze EEZ fishery statistics and other related information. On the other hand, the Deep Sea Fishing Authority Legislation requires all licensed vessels to report fish caught in the EEZ of United Republic of Tanzania (URT) on daily basis. Furthermore, Tanzanian flagged fishing vessels are required to report fish caught in the international waters. Also, other information regarding specifications of fishing vessels applying for fishing licences, records of fishing vessels that have received fishing licences are being kept in the Data base.
The historical record of fish caught in the EEZ of URT shows that catch of the tuna and tuna like species within Tanzania EEZ varies from year to year but an average of about 8,000 metric tons/year has been observed. Furthermore, catch distribution charts for the tuna and tuna like fisheries in the Indian Ocean, shows that purse seine catches are highest on the edges of the Tanzanian EEZ.
Generally, the purse seine fleet has been observed to operate from March through to November with high catch seasons in March, August, and November as it is shown on the figure below.
