The Artificial Reef Program used four types of obsolete Army armored vehicles as artificial reef materials off the New Jersey coast. These were cleaned at local military bases, loaded onto barges for transport, and pushed off at their final destination. Once the Army had disposed of its excess inventory, the program ceased, around 1999. The Artificial Reef Program has sunk almost 400 tanks altogether, far too many to list them here in this website.
Eastern or 'Chain' pickerels are deep olive-green on the back, shading to a creamy yellow on the belly. Olive green blotches are present within distinct black chain-like or interwoven markings on the sides. There is a distinct dark, vertical bar below the eye. The cheek and gill covers are completely covered by scales. The underside of the lower jaw has 14-17 branchiostegal rays. There are no recognized subspecies. However, they hybridize readily with redfin pickerels. They are distantly related to trout and salmon.
