Morphohometric Relationships in the Western Atlantic Loggerhead
Turtle, Caretta." Draft Report, NMFS.
The relationship of total tail length to total straight-line carapace
length was found to be an accurate indicator of sex in mature male turtles,
and is assumed to be a good indicator of sex in adult female turtles as well.
In subadult turtles, the tail measurement does not appear to be a usable
indicator of sex.

Migrations of Immature Kemp's Ridley Turtles (Lepidochelys kempi)
and Green turtles (chelonia mydas) Off Florida, Georgia, and South
Carolina." Northeast Gulf Science, 9(2):153-159.
This paper presents results of sea turtle research at Cape Canaveral, FL
from 1978-1984. Captures of Kemp's ridley and green turtles were analyzed to
determine seasonal occurrence, size composition, and movement patterns. For
Kemp's ridley, additional capture records from Georgia and South Carolina were
included in the analyses for comparative purposes.

Turtle Captures and Mortalities During Commercial Shrimp
Trawling." Fishery Bulletin, Notes, 85(4):813-816.
This report provides a preliminary analysis of existing data collected
by fisheries observers during commercial U.S. shrimp trawling. Estimated
turtle CPUE and mortalities for loggerhead, Kemp's ridley, and green turtles
are provided.

Regulations, Including Estimates of Shrimp Trawler Related
Mortality in the Greater Caribbean." Draft Report, USDOC, NMFS,
SERO, 9450 Koger Blvd., St. Petersburg, FL 33702, 20 pp.
Sea turtle catch and mortality by U.S. shrimp trawlers under current sea
turtle conservation regulations and import restrictions were evaluated. This
required a rather complex analysis of shrimping effort, turtle catch rates,
turtle mortality rates, effectiveness of TEDs and tow time restrictions, and
compliance with existing regulations. Results of these analyses were used in
determining (1) whether changes in existing regulations to provide additional
protection to endangered and threatened sea turtles were warranted and (2) the
rates with which foreign, shrimp importing nations would have to comply under
P.L. 101-162.
