Diet Content And Overlap Of Six Species Of Turtle Among The Wabash River, Lori Pierce
Diet Content And Overlap Of Six Species Of Turtle Among The Wabash River, Lori Pierce
Masters Theses
A community of six species of turtles from the Wabash River and its backwaters was studied to determine diet composition of each species and amount of dietary overlap among species. Species studied included: Trionyx muticus, Trionyx spiniferus, and Graptemys ouachitensis in the river; Trachemys scripta and Chrysemys picta in both the river and backwaters; and Chelydra serpentina in the backwaters only.
Trionyx muticus, T. spiniferus, and G. ouachitensis all belong to a guild that specializes on aquatic insects. The highest diet overlap (69.6%) was between the two softshells, T. muticus and T. spiniferus. Coexistence is possible because T. spiniferus are …
Bivalve Aquaculture In Warm Tropical And Subtropical Waters With Reference To Sanitary Water Quality, Monitoring And Post-Harvest Disinfection, Michael A. Rice
Bivalve Aquaculture In Warm Tropical And Subtropical Waters With Reference To Sanitary Water Quality, Monitoring And Post-Harvest Disinfection, Michael A. Rice
Michael A Rice
The warm water and high primary productivity of tropical estuaries allows for rapid growth and production of bivalves, but sanitary quality of molluscan shellfish poses one of the single largest impediments to development of international markets. The regulations of the US Food and Drug Administration (FDA) are outlined as representative of regulations governing international trade of fresh and frozen molluscan shellfish. The status of shellfisheries and molluscan aquaculture in several tropical and subtropical nations is presented. A number of developing nations, including Mexico, Peru and the Philippines, have established export markets for fresh scallop adductor meats because they are not …
