Effects Of Artificial Substrates On The Recruitment Of Juvenile Fishes In The Northwestern Gulf Of Mexico, Stefany Salinas
Theses and Dissertations
Most artificial reefs (ARs) in the Gulf of Mexico are considered intermediate to high vertical relief structures which have recruited large predatory species indicating lack of juvenile habitat. Small, inexpensive ARs, standard monitoring units for the recruitment of reef fish (SMURFs), were deployed at eight sites at -20m as habitat for juvenile fishes to understand and determine the effects of substrate type on juvenile fishes recruitment. Each site contained four SMURFs with four treatments: small and large rubble (~10 and ~20cm), oyster shells, and bare. Surveys yielded 39 juvenile species, including one of the most economically important species, Lutjanus campechanus, …
