1 What’s the Catch? Additional Case Study Data

2 Coastal SEES Model

Black Sea Bass (Centropristis striata) Data are from:

Black Sea Bass (Centropristis striata) Data are from:

5 Black Sea Bass off the Coast of Long Island
The chart presents data collected from NOAA’s National Marine Fisheries Service (NMFS) which shows the average weight (kg) of black sea bass caught per “tow” by their research vessels off the coast of Long Island, NY. A tow refers to each time they pull in their survey net. This value is interpreted as a measure of the amount of fish in an area.

6 Data is from http://oceanadapt. rutgers. edu/regional_data
Data is from The units are in kilograms per survey tow. The values are the average changes in the amount of black sea bass caught in the spring survey. These values do not reflect what is being caught by fisheries. Red indicates where the surveys caught increased amount of black sea bass, and the blue reflects where there was little or none.

Source: (Scup) (Black Sea Bass) Some co-wintering guild species, e.g. scup (Stenotomus chrysops) (Austen et al. 1994), may be competitors for habitat or food The Northeast Fisheries Science Center (NEFSC) food habits database lists the following species as predators of black sea bass: spiny dogfish (Squalus acanthias), Atlantic angel shark (Squatina dumeril), clearnose skate, little skate (Raja erinacea), spotted hake, summer flounder, windowpane, and goosefish (Lophius americanus).

12 Changes in Fishing Communities

13 The chart presents fisheries data collected from NOAA’s National Marine Fisheries Service (NMFS) which shows the average weight (metric ton or 1000 kg) of black sea bass caught by commercial fishing vessels.
