The Impact of Crown Conch on Intertidal Oyster Populations in Mosquito Lagoon

By: Casey Craig, Courtney Buck, Chelsea Landau, and Jordan Filipponi | Mentor: Dr. Linda Walters

The Impact of Crown Conch on Intertidal Oyster Populations in Mosquito Lagoon Commercial oyster harvesters in Florida have long complained that the Florida crown conch Melongena corona is in competition with them for harvestable-sized eastern oysters (Crassostrea virginica). Harvesters also suggest that crown conch, rather than overharvesting, has led to a large decline in oyster populations. To determine the role of M. corona on oysters in Mosquito Lagoon, we must first better understand the biology and ecology of M. corona , and to comprehend crown conch biology in Mosquito Lagoon along the east coast of central Florida, we conducted a three-part experiment in the Canaveral National Seashore (northern Mosquito Lagoon).

Preventing Introductions to Sustain Healthy Ecosystems: Establish Eradication Protocols for a Popular Aquarium Seaweed

By: Julie Deslauriers| Mentor: Dr. Linda Walters

Preventing Introducations to Sustain Healthy Ecosystems: Establish Eradication Protocols for a Popular Aquarium Seaweed Aquarium release, a vector that introduces non-native species, recently caused the costly invasion of the green macroalga (seaweed) Caulerpa taxifolia along the Californian, Mediterranean, and Australian coasts. C. taxifolia was classified by the International Union for the Conservation of Nature as one of the world's 100 worst invasive species and cost California over $7 million to control with black tarps and chlorine bleach. Since the incident, educational efforts at conferences and conventions have influenced more than 50% of surveyed hobbyists to switch to another green macroalga, Chaetomorpha, as their primary alga in their saltwater tanks.
