Produktbeschreibung
Excerpt from Proceedings of the Academy of Natural Sciences of Philadelphia, Vol. 63 The waters of the State of Delaware may well be included in the marine fauna known as the Virginian, which is not essentially different from that of New Jersey. The extent of sea-coast is comparatively short, about 23 miles, and from this little positive information has yet been obtained. Several years ago the deep-sea pound established off Dewey Beach was abandoned, so that no important fish industry is carried on at present. Many of the off-shore fishes are said to have been taken in the pound, and some of them quite frequently. The surf fauna along the beaches, which are usually moderately inclined and easily seined in many places, furnishes schools of smaller fishes, such as Mugil, Trachinotus and Menticirrhus. Crustacea, such as Ocypode albicans, Callinectes sapidus, Ovalipes ocellatus and Emerita talpoida, are abundant and often constitute the food of many fishes. The bays present peculiarities in their tides. The greatly larger area of Delaware Bay has a broad outlet to the sea with the usual tidal, allowing a great influx of marine forms, most of which ascend to Ship John Light or Bombay Hook Point. On the other hand, though both Indian River and Rehoboth Bays are salt water, they have little or no tides, as the only channel of egress to the sea is the Indian River Inlet, which being very narrow allows only a comparatively small escape and inflow of water. However, marine fishes enter these bays by this passage, and sometimes in numbers. Uca ranges along the salt and brackish marshes as far north as Armstrong´s Creek in Newcastle County. Prawns, like Palcemonetes vulgaris, occur almost everywhere. The fresh-water fauna may be divided into a tidal and an abovetidal region, of which the latter may again be divided into a lowland and an upland region. The first of these is largely homogeneous throughout the drainage of both the Delaware and Chesapeake Bays. Acipenser sturio, Lepisosteus, Pomolobus pseudoharengus, Alosa, Osmerus, Ameiurus catus, Fundulus heteroclitus macrolepidotus Tylosurus, Roccus and Morone are characteristic. Apeltes quadracus, not yet taken in the State, may also occur, likewise Dorosoma cepedianum. Pal monetes vulgaris is the most abundant crustacean.
