Introduction: This study aimed to evaluate the status, resource use, and
challenges of the capture-based hatchery of black tiger shrimp (Penaeus
monodon) (BTS).
Methods: Data was obtained through the investigation of 15 broodstock fishing
boats and 60 capture-based BTS broodstock hatcheries. Resource use index
(RUI) of the capture-based BTS hatchery, calculated from 1,000 female brooders
to produce 15-day-old post-larvae (PL15) (production efficiency of PL15, or PEPL15), was analysed.
Results: The results indicated that the fishing boats captured an average of 5,900
brooders.boat-1.year-1, 20,856 kg of by catch.boat-1.year-1, and the PE-PL15
production of 937 million for 1,000 female brooders. In the hatchery stage, the
use of larger body weight female brooders had benefits in terms of higher survival
rate and better efficiency of labour use, Artemia cyst, and probiotic products, but
it reduced the efficiency use of chemicals, pellets, and total tank volume of
the hatchery.
Discussion: There is increasing use of domesticated brooder sources, but wildcaught brooders still play an important role in producing low-cost PL15 for
traditional shrimp farming systems, accounting for most farmed BTS
production. Therefore, the certification of good practices should be
implemented to capture-based BTS hatcheries for the reasonable use of this
brooder resource to sustain BTS farming in Vietnam.
