Mortality estimates of striped bass caught in Albemarle Sound and Roanoke River, North Carolina Mortality estimates of striped bass caught in Albemarle Sound and Roanoke River, North Carolina
A statistical analysis of the age composition of striped bass Morone saxatilis harvested in Albemarle Sound and the Roanoke River, North Carolina. indicated that in 1988–1992 the population experienced a relatively high rate of total mortality. Age-3 and older fish were estimated to have been fully vulnerable to fishing mortality and to have experienced a total instantaneous mortality...

Technology transfer opportunities : new development : new protocol verifies sterility of newly hatched fish Technology transfer opportunities : new development : new protocol verifies sterility of newly hatched fish
U.S. Geological Survey's Biological Resources Disicipline scientists have developed a procedure that could save commercial producers of triploid grass carp between $2000 and $3000 per pond. Since 1983, triploid grass carp have been commercially available for managing aquatic weeds that can cause water quality problems, replace native plants, or impede recreational and commercial use of...

A sexing technique for California Gulls breeding at Bamforth Lake, Wyoming (Una tecnica para determinar sexos en larus californicus reproduciendose en el Lago Bamforth, Wyoming) A sexing technique for California Gulls breeding at Bamforth Lake, Wyoming (Una tecnica para determinar sexos en larus californicus reproduciendose en el Lago Bamforth, Wyoming)
We used morphological characteristics to determine the sex of California Gulls (Larus californicus) nesting at Bamforth Lake, Wyoming. Using univariate and multivariate techniques, we evaluated sexual dimorphism in five external measurements taken from 614 California Gulls: bill length, bill depth, head-bill length, tarsus length, and body mass. Males were significantly larger than...

Marsh vertical accretion in a Southern California Estuary, U.S.A Marsh vertical accretion in a Southern California Estuary, U.S.A
Vertical accretion was measured between October 1992 and March 1994 in low and high saltmarsh zones in the north arm of Tijuana estuary from feldspar market horizons and soil corings. Accretion in the Spartina foliosa low marsh (2-8.5 cm) was related almost entirely to episodic storm-induced river flows between January and March 1993, with daily tidal flooding contributing little or no...
