Although the bonefish was previously thought to be the only member of the Albulidae family, there are now five recognized species. The bonefish is the only significant sportfish among them, however, and is one of the most coveted of all saltwater gamefish. In keeping with its scientific name, which means “white fox,” it is indeed a wary, elusive creature, one that usually must be stalked with stealth and that bolts with startling speed when hooked or alarmed.
Although bonefish have little food value to anglers and virtually all are released, they are a subsistence food in some locations. It is generally believed that bonefish are not good table fare, but some gourmands maintain that bonefish flesh is firm and tasty and the roe a delicacy.

Identification of Bonefish
The bonefish has armor plates, instead of scales, on its conical head and is distinguished from the similar ladyfish by its suckerlike mouth and snout-shaped nose, which are adapted to its feeding habits. It also has a single dorsal fin and a deeply forked tail. The coloring is bright silver on the sides and the belly, with bronze or greenish-blue tints on the back; there may also be yellow or dark coloring on parts of the fin and the snout, and sometimes there are dusky markings on the sides. The young have bronze backs and nine narrow crossbands.
Size of Bonefish
Although the average bonefish weighs between 2 and 5 pounds, bonefish weighing up to 10 pounds are not uncommon. They can grow to 41 inches in length, averaging 1 to 21⁄2 feet long. The all-tackle world-record catch is a 19-pound fish.
The particulars of bonefish reproduction are not well known, although it is thought that bonefish spawn from late winter to late spring, depending on locale. With a small head and a long, transparent body, the young bonefish looks like an eel until it undergoes a leptocephalus larval stage. It grows to about 21⁄2 inches long during this period, then experiences a metamorphosis that shrinks the young bonefish to half that size. The fins begin to appear during the shrinking, and in 10 to 12 days it attains the adult bonefish body form, only in miniature size.
This growth process is similar in tarpon and ladyfish development. The young migrate out to the open sea to live on plankton, returning as juveniles to live in the shallows. Generally, bonefish are a schooling fish; smaller specimens are seen traveling in large numbers on the flats, whereas larger ones prefer smaller schools or groups of 5 to 10 fish.
Food and feeding habits
Bonefish feed on crabs, shrimp, clams, shellfish, sea worms, sea urchins, and small fish. They prefer feeding during a rising tide, often doing so near mangroves.
They root in the sand with their snouts for food and are often first detected while feeding with their bodies tilted in a head-down, tail-up manner, with all or part of their tail fins protruding from the surface. These are referred to as tailing fish. Bonefish also sometimes stir up the bottom when rooting along, which is called mudding; this can be a telltale indicator to the observant angler.
Bonefish are found worldwide in tropical and subtropical waters. Around North America, they are most bountiful in the Florida Keys, the Bahamas, and the Caribbean, more so in the winter than in the summer; they are also somewhat abundant in Belize, Panama, and other Central American countries.
Occurring in warm coastal areas, bonefish inhabit the shallows of intertidal waters, including around mud and sand flats, as well as in mangrove lagoons. They are also found in waters up to 30 feet deep and are able to live in oxygen-poor water because they possess lunglike bladders into which they can inhale air.
