Carp and tench are pond rather than river fish, and both have a great fondness for burying themselves in mud, and owing to this the flesh has often a slight muddy taste; for this reason the fish should lie in strong salt and water for a few hours, then be well cleansed in clear spring water.
Both are at their best in the winter months. The tench, though a smaller fish, is richer and more delicate than the carp. They are useful fish to families residing in the country.
Although the pike attains to a considerable size in England, it is small in comparison with its brethren found in Russian and Lapland waters. Indeed it more truly deserves to be called a Russian fish, so much more abundant and popular is it there. In colour the skin is a pale olive-grey, with several yellowish spots on the sides, and the mouth is furnished with a prodigious number of teeth, which has earned for it the name of "fresh-water shark."
It was at one time a very popular article of food, and is still considered a good fish for the table. In some countries the fish is salted and dried, and the roe made into caviare.
The perch, which is one of the commonest of our fresh-water fish, is also one of the best. It is met with in almost all lakes and rivers in temperate regions. When full-grown it is a large fish, although one weighing a pound is thought a good size, and one of three pounds very large. The flesh is white, firm, of a good flavour, and easily digested.
Perch are so tenacious of life, they may be carried fifty miles and yet survive the journey.
Best used as soon as caught, they are also better for being crimped as soon as they leave the water. Their season is from June to February.
Perhaps the most commonly used fish is the herring. Shoals of herring visit the British Islands from the end of May till October, and even occasionally during the winter months. In the beginning of the season the fish is rather oily, and often found to be indigestible on that account, but after the first few weeks this disappears, and then it becomes both digestible and nourishing.
In choosing herrings take care that they feel firm, and have bright eyes and scales.
