They are fed a range of diets, from trash fish to basic compound feeds to complex, formulated, compound feeds.

There are environmental concerns over certain feeds used fishmealoilstrash fish, etc. Escape of cultured fish is also a seriola dumerili aquaculture, which can have effects on wild stocks in terms of competitionpredation and genetic alterations, depending on vulnerability and robustness.

Insights into molecular seriola dumerili aquaculture may contribute to a better understanding of traits like growth and sex, but investigations to unravel the molecular background of amberjacks have begun only recently. Illumina HiSeq sequencing generated a high-coverage greater amberjack genome sequence comprising 45 scaffolds.

British coast vagrant to Morocco and the Mediterranean. Distribution in eastern central Atlantic along the African coast is not well established due to past confusion with Seriola carpenteri Ref. In Japan the seed is caught from the wild but there seriola dumerili aquaculture increasing hatcheries producing juveniles for grow-out in other Asian countries.

Greater amberjack juveniles are being produced on a small scale in Europe and there is increasing interest from a number of countries, namely Spain, Greece, Malta and Italy. The wild juveniles farmed in Japan are mostly caught in nearby waters, but some are captured and imported from other Asian countries.


The number of juveniles imported from Seriola dumerili aquaculture and Viet Nam was about 20 million in The females release eggs with a periodicity higher that other species about once weekly.

Natural spawns have been observed in captivity.

Seriola - Wikipedia

However, reproductive failure often occurs in captivity, and hormonal therapies to induce spawning are applied to females and seriola dumerili aquaculture maintained in tanks or cages. The fertilized eggs float and are spherical about 1 mm in diameter and 1 oil droplet of 0.

These fertilized eggs are floated in incubators — eggs per litre and hatch within 30—45 hours. The incubator tanks are supplied continuously with filtered seawater and gentle aeration to prevent clogging of the outlet sieves.

Once or twice a day the seawater circulation and aeration are stopped so that any non-floating or dead eggs are removed to maintain optimal water conditions.


Seriola dumerili aquaculture newly hatched larvae about 3. For best results, newly hatched larvae are reared in large, circular tanks with a volume greater than 20 m3 at low densities 5—10 larvae per litre. However, higher densities and lower volumes have been tested but this technology is not fully developed.

Normally the larvae are supplied with live feed.

FAO Fisheries & Aquaculture Seriola dumerili

Enriched rotifers, Brachionus plicatilis, are used during the first three to four weeks, often in combination with algae either freshly produced or concentrated.

Artemia nauplii are added at 12—16 days post hatching dph and Artemia metanauplii from 20—25 to 40—50 dph. At 25—30 dph formulated feed seriola dumerili aquaculture supplied and the size particles are increased according to the age and size of larvae. During larval rearing there are often two mortality spikes.

The first is related to the start of feeding when the larvae open their mouths and the eyes become pigmented between 3—4 dph.

Human uses

The swim bladder inflation occurs at 5—9 dph. This mortality peak can be a result of inappropriate prey size or inadequate conditions for first feeding.
