| Summary: | Culture models and facilities for large-scale, commercial
production of popular Gulf of Mexico species are
unavailable. The spotted seatrout (Cynoscion nebulosus) is
one of the most popular recreational fishes in the Gulf of
Mexico. Seatrout culture techniques were adapted from red
drum (Sciaenops ocellatus) protocols developed in the
1970s. Broodstock husbandry, spawning, and extensive
pond rearing techniques using fertilized and bloomed brackish
ponds were well-established by the 1980s. By 2018,
approximately 80 million 25–30-day old seatrout had been
produced, mainly for stock enhancement. Cannibalism and
poor nutrition hindered intensive tank culture. Between
2005 and 2015, an intensive tank-rearing protocol that
reduced cannibalism and intracohort variability and
increased average survival to almost 50% was developed
using algal concentrate, rotifers, brine shrimp (Artemia sp.),
and microencapsulated feeds. Preliminary results suggested
that a 500 g fish could be produced in approximately
10 months. Nevertheless, interest in commercialization has
remained low. Zootechnical performance throughout the
latter stages of culture, the economics of production, consumer
preferences/perceptions, and market capacity must
be documented to complete the assessment of the spotted seatrout as a species for commercial aquaculture. The optimization
of aquafeeds specific for seatrout and a domestication
program is warranted to further facilitate industry
growth. |
