LUTJANUS ARGENTIVENTRIS PDF

Over 1, juvenile individuals were collected and otoliths were aged to describe the temporal pattern of the settlement. The majority of mangrove sites in the Gulf of California had a similar L. When sub-adults leave mangroves, they live in shallow rocky reefs and later become abundant in deeper rocky reefs. This finding has important implications for local fishery regulations and coastal management plans.

This fish is also known as the Amarillo Snapper. Globally, there are sixty-seven species in the genus Lutjanus, nineteen of which are found in Mexican waters, ten in the Atlantic and nine in the Pacific. The Yellow Snappers have moderately oblong bodies with an overall yellow coloration that is more prominent in the tail and lower part of the body. Larger adults are two-toned, rosy-red in the front and yellow in the back.

Their fins are yellow or orange. They have a distinctive blue horizontal streak below their eyes, that provides a facile identification, that fades quickly after collection. They have a pointed snout and a large mouth.

Their anal fin is rounded with 3 spines, the second being thick, and 8 rays; their caudal fin is straight; and their dorsal fin is continuous and rounded at the terminal end with 10 spines. The Yellow Snappers are found over rocky bottoms close to caves and crevices at depths up to feet. They reach a maximum length of 76 cm 30 inches. They are nocturnal predators feeding on crabs, mollusks, octopus, shrimp, and small fish and take shelter during daylight.

Juveniles will enter fresh water streams. In Mexican waters the Yellow Snapper are found in all waters of the Pacific. The Yellow Snapper is an easy fish to identify due to its coloration and the broken blue line under the eyes and cannot be confused with any other species. The Yellow Snappers are considered an excellent food fish.

They are not caught in abundance by hook and line as they virtually disappear shortly after the first morning light. They occasionally become accessible in the early morning when chummed up to near the surface with cut bait.

They are also accessible from the beach but only during predawn hours with live sardines being the bait of choice. They are sold in many markets of the greater Los Cabos area with fish presumably caught via nets and brought in from unknown locations.
