the shad are treated from time to time with melted butter. There is no
other way which a shad can be cooked which renders it so delicious as
by this primitive method. The shad, from an economic point of view, is
third in importance in the United States, only the salmon and the cod
exceeding it in value. The annual catch of shad on the Atlantic sea
coast numbers from 10 to 20 million, weighing from 40 to 60 million
pounds and worth from one and one-half to two million dollars.
_Composition of Shad._--
FRESH. DRY.
Water, 70.62 percent
Protein, 18.56 „ 64.36 percent
Fat, 9.47 „ 31.93 „
Ash, 1.35 „ 4.62 „
Of the whole weight of shad the average edible portion amounts to 52.35
percent, and the refuse, counting the bones, skin, and entrails is
47.65 percent.
_Shad Roe._--The eggs of shad, as has already been mentioned, are
regarded as the most valuable portion of the fish. Roe shad also are
more highly prized as a food fish than the male shad. As a result, roe
shad sell for a much higher price on the market than the male shad. The
eggs are quite small, and as has already been said, occur in immense
numbers, the average number to a fish being about 30,000.
_Composition of Shad Roe._--
Water, 71.2 percent
Protein, 23.4 „
Fat, 3.8 „
Ash, 1.6 „
Aside from the water of the roe, it is noticed that by far the most
abundant component is the protein. This, of course, is what would be
expected of an egg product. The protein is a little more than six times
as great as the fat. The ash contains large quantities of phosphorus,
which exists in the original egg, largely in the form of lecithin,
in which state it is regarded as most valuable for nourishing the
phosphatic tissues of the body. Shad roe is eaten almost entirely in
the fresh state. It does not produce a pickled or cooked product of
anything like the value of the sturgeon eggs. So far as the author
knows no form of shad egg preparation similar to caviar is on the
market.
There are three species of shad in America, but the only one of great
importance is the common Atlantic shad which has been described.
=The Sheepshead.=--This abundant and important food fish exists in
large numbers along the Atlantic coast. It also belongs to the Sparidæ
and its scientific name is _Archosargus probatocephalus_. This species
is found from Cape Cod to Texas. It is especially found in the vicinity
of oyster beds, where it is destructive to the oysters. It is quite
abundant in the Indian river, being, next to the mullet, the most
frequently found fish in those waters. Though strictly a salt-water
fish, it often runs up into fresh waters. The fish is distinguished by
the number of broad silvery colored bands extending around its entire
body. The average weight of the sheepshead is three or four pounds,
though occasionally a fish three or four times that size is captured.
