Cutlass Fish

 

(Trichiurus japonicus), a fish of the family Trichiuridae. The naked, elongate, and silvery body resembles a cutlass. The cutlass fish reaches a length of 2 m and a weight of 1 kg. It inhabits the Sea of Japan, the East China Sea, and the South China Sea. The fish is found off the shores of India, western Africa, and Primor’e Krai (USSR). A marine school fish, it feeds on sardines. The cutlass fish has some commercial value.

The Argentine anchoita (Engraulis anchoita [Engraulidae]), rough scad (Trachurus lathami [Carangidae]), Atlantic cutlassfish (Trichiurus lepturus), Brazilian sardinella, and flying gurnard (Dactylopterus volitans) were the most abundant species (70% of the total biomass sampled).
The Atlantic cutlassfish and Brazilian sardinella, also abundant, displayed high frequency in the aggregations over the years ([FO.sub.T]=70% and 51%, respectively), also indicating wide distribution and persistency (Table 4).
At Los Cantiles and Isla Granito important prey were lanternfish (Diaphus sp.), northern anchovy (Engraulis mordax), Pacific cutlassfish (Trichiurus nitens), shoulderspot (Caelorinchus scaphopsis), and Pacific whiting (Merluccius productus) (Sanchez-Arias, 1992; Bautista-Vega, 2000), whereas at Isla Racito, important prey were Pacific sardine (Sardinops caeruleus), Pacific mackerel (Scomber japonicus), grunt (Haemulopsis spp.), rockfish (Sebastes spp.), and Pacific whiting (Merluccius spp.) (Orta-Davila, 1988).
We found nine main prey with IIMP average values [greater than or equal to] 10% (Table 3): the Pacific cutlassfish (Trichiurus lepturus), the Pacific sardine (Sardinops caeruleus), the plainfin midshipman (Porichthys spp.), myctophid no.
Yet, hard parts such as whole or sectioned otoliths and vertebral centra are most frequently used to age cutlassfish (Table 1).
The aims of our study were 1) to validate age estimates by using transverse sections of sagittal otoliths; 2) to verify Lee's phenomenon; 3) to evaluate the potential of using otolith size and weight to estimate age; 4) to fit the age-length data to the von Bertalanffy growth model; and 5) to provide age-growth information for management of cutlassfish resources from the South China Sea.
