National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Biological Aspects of the Calico Scallop, 'Argopecten gibbus', Determined by Spat Monitoring.

Abstract	Biological information on the calico scallop, Argopecten gibbus, was collected using spat traps as monitoring devices on the Cape Canaveral grounds off the Florida east coast from March 1970 to October 1971. The shells of young scallops (spat) differ in shape and color from those of adult scallops. Spat and, by deduction, the larval scallops, occurred at five sampling locations off Cape Canaveral in depths of 9 to 24 m; spat were most abundant at the 18 m site. There was no evidence that scallop larvae survived in estuarine waters in the Cape Canaveral area. Based on spat distribution, larvae were apparently distributed throughout the water column but were least abundant near the surface. Seasonally, spat were most abundant in the spring. Spat may utilize filamentous host organisms, such as hydroids, for setting, perhaps before attachment to shell. Numerous invertebrates were associated with calico scallops in the traps, but calico scallops were generally dominant.
