Skipjack Tuna   Japanese name: Katsuo 

Also known as Striped Tuna or Stripies.

Skipjack Tuna are dark blue or purple on the back and silvery on their lower sides and belly.  They have three to five prominent, dark longitudinal bands on their lower sides.  These tuna have fine, slender teeth, a strong median keel on the caudal fin base between two small keels, and barely separated first and second dorsal fins.,   They have a total of 53-63 gill rakers on the first gill arch.

 They normally inhabit waters with surface temperatures of 20ｰC to 30ｰC.  However, adults are sometimes present waters as cold as 15ｰC.  Skipjack tuna also need a dissolved oxygen level of 2.5 ml per 1 of sea water to maintain a minimum swimming speed and require higher levels when active.   This requirement generally restricts skipjack tuna to water above the thermocline and in some areas, may exclude them from surface waters.

The depth range of skipjack tuna can be from surface waters to 260m during the day, but at night it is much shallower.  Skipjack tuna are a schooling fish having a general tendency to school by size.

In tropical waters reproductively active female skipjack tuna spawn almost daily.   Ripe skipjack tuna eggs are about 1mm in diameter and transparent and buoyant.   Estimates of the number of eggs released at each spawning range from about 100,000 eggs for the smallest mature females to 2 million for the largest fish.  Skipjack tuna eggs hatch after 1-1.5 days.

Skipjack tuna are commonly caught by sport and recreational anglers.  Most fish are caught by trolling or casting small lures from a boat.  Catches are also made using flies or baits of whole, small fish or flesh strips.  Skipjack tuna are a very good bait for a variety of marine fish, with large skipjack tuna being used for the larger species of tuna and billfish.

Yellowtail Tuna   Japanese name: Inada

Also known as Allison Tuna and (Hawaii)

The caudal fin of the yellowfin tuna is distinctly notched in an "M" shape at the center of its fork.  Behind the second dorsal fin and the anal fin, the body profile of the yellowfin tuna is somewhat flat.  The ventral surface of the liver is smooth and the right lobe is longer than the central lobe.

Yellowfin tuna adults are distinguished by having a moderately long pectoral fin that is one third to one quarter the body fork length.  In juveniles there are about 20 broken pale lines crossing the lower sides.  In large fish, the second dorsal and anal fins may be exceedingly elongated and bright yellow.  Yellowfin tuna less than 75cm fork length (10kg whole weight) may be difficult to distinguish from small bigeye tuna. 

A beautiful and colourful tuna.  Blue to steel black above, silver to silvery gold on the flanks, silvery white below.  In fresh fish a band of bright gold or iridescent blue (sometimes both) runs along the upper flank, separating the dark back from the lighter belly area.

The stomach area sometimes carries oval, colourless patches and vague broken vertical bars of white.  These are more obvious in juveniles.

The yellowfins fins are bright yellow.  The finlets, in particular are canary yellow with black margins.

In Japanese waters fish of between 2 and 5kg. In other countries Yellowfin have been recorded in excess of 150kg.

Yellowfin is a very good eating fish.  It is extremely good as sashimi (raw fish).

Yellowfin Tuna are found close inshore, in clean warm currents.  They prefer clean water with water temperatures of 17-27ｺC.  They rarely venture into dirty, discoloured areas.

Yellowfin feed both on the surface, and well down in the water column.

Small yellowfin (2-12kg) will take trolled and cast lures, small live baits and sometimes freely drifted pilchards or cut flesh strips.  Larger yellowfin take small and medium live baits, up to and including live frigate mackerel, bonito and striped tuna weighing as much as 5kg plus.

Yellowfin are extremely powerful and demand the best in tackle and gaffs!
