=Horse Mackerel.=--Another species belonging to the mackerel family is the horse mackerel or tuna (_Thunnus thynnus_), which is found in considerable abundance on our North Atlantic coast and on the coast of southern California. Its common name is “tuna,” “tunny,” “horse mackerel,” or “great albacore.” The horse mackerel is a fish of very great size and is the very largest of the whole mackerel family. They occasionally attain a length of 10 feet or more and a weight of 1500 pounds. The average dimensions, of course, are very much less than this. The horse mackerel does not grow so large in Europe or upon the Pacific coast. In these regions a horse mackerel weighing 500 pounds is considered of an extraordinary size. The very large ones are never taken with hook and line, but there are records of fish of over 200 pounds that have been captured in this way. =The Hogfish.=--The hogfish of the West Indies and our southern coasts is another of the wrasse-fishes whose scientific name is _Lachnolaimus maximus_. It is called in Porto Rico “el capitan.” It often reaches a weight of 20 pounds and a length of from 2 to 3 feet. The name “hogfish” doubtless is derived from the shape of the head, which resembles somewhat that of the hog. It is valued as a food fish throughout the West Indies. =Lake Herring.=--The so-called lake herring is very closely related to the whitefish. The name of the species is _Argyrosomus artedi_. The lake herring has a large number of common names, of which the most widely applied is the term “Cisco.” The terms blueback, greenback, and grayback are also applied to these herring. The habitat of this fish is that of the whole region of the Great Lakes and north to Hudson Bay. It has much the same habitat as the whitefish. The average weight of the lake herring is about one pound. The subspecies (_Argyrosomus artedi sisco_) is found in Lake Tippecanoe and other small lakes in Wisconsin and northern Indiana. _Composition of Cisco._-- FRESH. DRY.

Its habitat is principally the North Atlantic ocean. On the coast of the United States it is found from Cape Hatteras north to the Strait of Belle Isle. In Europe it is found from Norway southward to the Mediterranean and Adriatic. The mackerel on the Atlantic coast usually appear first in the spring near Cape Hatteras and following the custom of the shad are found later farther north in the New England states and also in the British possessions. They leave the coast in the inverse order in the autumn, disappearing first in the northern regions and later in the southern portion.
