Juvenile Blue Crab (Callinectes Sapidus) Survival In Simulated Seagrass Habitats (Zostera Marina And Ruppia Maritima), Kylie Smith Jan 2017

Juvenile Blue Crab (Callinectes Sapidus) Survival In Simulated Seagrass Habitats (Zostera Marina And Ruppia Maritima), Kylie Smith

Undergraduate Honors Theses

Anthropogenic increases in global temperatures and nutrient loads are expected to reduce juvenile blue crab (Callinectes sapidus) survival in the Chesapeake Bay. These factors change habitat composition which can affect juvenile invertebrates and fishes that are dependent on these habitats. Eelgrass (Zostera marina) is declining due to rising water temperatures and increased nutrient loading, while widgeon grass (Ruppia maritima) can tolerate higher temperatures. An indoor mesocosm experiment was designed to test the suitability of Zostera and Ruppia as protective nursery habitats compared to sand. Artificial seagrass plots were placed in flow-through tanks. Juvenile blue crabs were tethered, and adult blue ...

Smooth Hammerhead Target Fishing And By-Catch In Puerto López, Ecuador: Trends In Catch And Recommendations For Mitigation, Lauren E. Degeorge

Undergraduate Honors Theses

Sharks have not historically been considered a valuable resource but, with the increase in demand for their fins, shark catch numbers have risen dramatically and many shark populations are suffering. It is difficult to know the extent of the problem because there is a lack of information about sharks and shark catch is vastly under-reported. The smooth hammerhead shark (Sphyrna zygaena) is valuable in the shark fin market for its eight, large fins and is frequently landed at the Puerto López fish market in Ecuador. EquililbrioAzul is a marine conservation organization that has been keeping track of shark catch in ...
