3 Motivation: Where are red snapper? Gallaway et al Rev in Fish Sci U.S. Department of Commerce National Oceanic and Atmospheric Administration NOAA Fisheries Page 3
4 There are a lot of artificial structures in the Gulf of Mexico U.S. Department of Commerce National Oceanic and Atmospheric Administration NOAA Fisheries Page 4

6 Basic study schematic Sampling and study domain Northern Gulf of Mexico, depths m (min/max depth for RS) Data Intensive longline, handline sampling in 2011 (CSSP), targeted sampling of platforms and reefs in other surveys, usseabed habitat data Statistical modeling merge different data sources and account for survey artifacts (e.g. sampling different areas at different times of the day) Predictive mapping Predict distribution by age, area, depth and habitat type on 10-km 2 grid U.S. Department of Commerce National Oceanic and Atmospheric Administration NOAA Fisheries Page 6
7 Sampling programs Congressional supplemental sampling Longline stratified random Handline stratified random Handline targeted natural reefs 2. Handline on platforms (SEAMAP) 3. Handline on artificial reefs (Powers, Drymon et al.) U.S. Department of Commerce National Oceanic and Atmospheric Administration NOAA Fisheries Page 7
8 Domains of inference Longline and randomized handline: everywhere but natural reefs, platforms and known artificial structures Targeted handline: natural reefs, platforms, or artificial reefs - area of influence assumed to be 100 m radius Reynolds, 2007 U.S. Department of Commerce National Oceanic and Atmospheric Administration NOAA Fisheries Page 8

17 Locally, artificial structures are extremely important U.S. Department of Commerce National Oceanic and Atmospheric Administration NOAA Fisheries Page 17
18 Caveats/assumptions Handline gear assumed to have same catchability among habitats Relies upon databases of known artificial reefs and platforms (underestimate of structures by half would be ~ two-fold contribution) Area of influence assumed to be constant across surrounding area and same for all artificial structures Snapshot of 2011 distribution platform survey in different year (2007) Artificial reef sampling limited to relatively small area Only relative abundance map Statistical model does not capture small-scale variability Maps would not work for identifying fishing locations U.S. Department of Commerce National Oceanic and Atmospheric Administration NOAA Fisheries Page 18
19 Conclusions Artificial structures can harbor the majority of Red snapper present in certain hotspots that are locally important for fishing opportunities But calculated across the entire Gulf, artificial structures comprise a small fraction of the total seafloor (~0.15%) and harbor a small fraction of the population (~13%). U.S. Department of Commerce National Oceanic and Atmospheric Administration NOAA Fisheries Page 19
20 Conclusions Because artificial structures harbor smaller, younger Red snapper than are found on natural reefs, their contribution to the overall stock is low in terms of biomass (8% of total) and spawning potential (6% of total). U.S. Department of Commerce National Oceanic and Atmospheric Administration NOAA Fisheries Page 20
21 Does this study answer whether artificial habitats increase the production of Red snapper in the Gulf of Mexico? No, though it does indicate that the relative impact of artificial reefs on red snapper production would be small due to the amount of this habitat relative to natural habitat U.S. Department of Commerce National Oceanic and Atmospheric Administration NOAA Fisheries Page 21
22 How does this study change the stock assessment? It doesn t. However, the study does help to scale the impact of potential differences in populations on artificial structures versus natural reefs. Current assessment models essentially average the rates of growth, mortality, and spawning across natural habitats and artificial reefs. Given the relatively small relative abundance on artificial structures, any differences would probably have a minimal effect on the stock assessment. If information on habitat-specific growth, maturity, fecundity, etc. becomes available, the results from this study would allow inclusion of this on the stock assessment. U.S. Department of Commerce National Oceanic and Atmospheric Administration NOAA Fisheries Page 22
23 What are the implications of this study for management? Artificial structures have important local fishery impacts that should be considered when interpreting fishery-independent data The detailed spatial map of red snapper abundance could be used to inform spatial management, survey design, or to further explore the potential implications of shifting biomass from natural reef to artificial reef areas Implications on stock status and catch advice are likely to be minor since catches from both natural and artificial reefs are already included in the assessment, and the proportion of red snapper that occupy artificial structures is small relative to the total population U.S. Department of Commerce National Oceanic and Atmospheric Administration NOAA Fisheries Page 23
24 Future directions What are the implications of shifting 8% of the biomass to locations it wouldn t normally be? U.S. Department of Commerce National Oceanic and Atmospheric Administration NOAA Fisheries Page 24
25 Future directions What effect has increasing artificial habitats had on stocks and the Gulf of Mexico ecosystem? 2017 Update coming next week!
