About the

Fish

The Bullet Tuna (Auxis rochei), also known locally as Tumbrell, is a small, tuna-like species that typically reaches lengths of between 40 and 50 cm in the Mediterranean. It forms shoals and lives in coastal waters and around islands.

Seasonality

In the Mediterranean, including Maltese waters, Bullet Tuna are most abundant during the warm months. Catches and spawning are at their peak in late spring and summer, generally from June to September.

How it's

Caught

Commercial fishermen primarily use surrounding or encircling nets to catch these schooling fish. Common methods include lampara nets, a traditional artisanal net used nearshore to scoop up surface schools, as well as purse seines and ring nets. These are common in both small-scale and semi-industrial Mediterranean fisheries.
For smaller-scale and recreational fishing, it’s often caught from small boats using trolling with small lures, light tackle, and handlines by sport and charter fishermen when they are found inshore. Small gillnets or coastal seines may also be used in artisanal fisheries.

Is it Good

to Eat?

Yes, Bullet Tuna is a delicious and commonly eaten fish. Its flesh is mild, firm, and meaty, making it a fantastic, high-value alternative to larger tunas. Due to its size, Mediterranean preparations prioritise quick cooking, salting, or curing to prevent them from becoming too tangy.

Common ways to

cook/prepare:

Grilled, pan-seared and/or broiled fillets
Salted and spiced (traditional preservation)
Canning and/or smoking
Roe

Safety

Small tunas like Bullet Tuna generally have lower mercury levels than larger tunas, but they are not mercury-free. Published analyses indicate that moderate concentrations can be present. If you are pregnant, nursing, or feeding young children, it is essential to follow national or local guidance on tuna consumption limits. Public health agencies often advise preferring smaller or younger fish and limiting consumption frequency.

Sustainability

& Status

The Bullet Tuna is a widespread and relatively abundant species, not considered to be at high risk like some overfished larger tunas. The pressure on this species locally comes mostly from small-scale coastal fisheries, rather than large industrial fleets. Scientific assessments treat small tunas separately, with management typically handled through regional bodies like the GFCM, ICCAT, and FAO.
