“…The hermatypic (or reef-building) CWC species Lophelia pertusa and Madrepora oculata excrete hard calcium carbonate skeletons as they grow, forming complex 3-dimensional reef structures that provide niches and nursery grounds for a variety of species, including commercial fish species like rockfish, orange roughy, and grenadiers (Costello et al 2005;Roberts et al 2006;Roberts et al 2009). However, their slow growth compared with most shallow-water zooxanthellate species and their high sensitivity to disturbance render CWC reefs particularly vulnerable to anthropogenic activities like fisheries, 188 F.

-Research on the biology and ecology of cold-water corals (CWCs) is still in its infancy. The growth patterns of CWCs in their natural environments are poorly known. Growth rate investigations on these deep-sea reef builder species are needed to predict recovery times following damage to their ecosystems. This study investigates a new approach for analysing CWC growth rate, suitable for in situ application. Lophelia pertusa and Madrepora oculata (Scleractinian) were collected from the Lacaze-Duthiers canyon in the northwestern Mediterranean Sea (520 m depth), marked and then either redeployed in situ for 6 months, or maintained in aquaria for growth rate comparison at a constant temperature of 13• C, corresponding to their habitat conditions. Two different types of staining (calcein and manganese) and three different exposure times (30, 60 and 240 min) were tested. The results show that calcein offers rapid incorporation and easy detection, making it particularly suitable for skeletal growth rate investigations compared with other chemical staining. In situ linear polyp growth rates of 7.5 ± 1.2 mm y −1 and 3.5 ± 2.1 mm y −1 were measured in new polyps of L. pertusa and M. oculata, respectively. Those values were significantly higher in young polyps than in older ones, where they decreased to 1.3 ± 1.5 mm y −1 and 1.2 ± 1.2 mm y −1 . Beyond the study of coral reef growth processes, this approach offers a methodological basis for habitat quality assessment which could be used in the management of deep-sea marine protected areas (MPA).

“…In deeper waters cold water corals (CWC) are thought to be one of the most biodiverse ecosystems and appear to act as a habitat for many species, including some of commercial value (Rogers 1999;Fosså, Mortensen and Furevik 2002;Husebø et al 2002;Costello et al 2005). The ecological role of cold water corals as a fish habitat has only recently emerged as an area of academic interest as well as an issue related to the conservation and sustainable use of deep-sea fishes and related biological diversity (Auster 2005).…”

“…They can be found in almost all the world's oceans. CWC are thought to provide nursery grounds and habitat for protection, reproduction and feeding for a number of species, including commercial fish species (Rogers 1999;Fosså, Mortensen and Furevik 2002;Husebø et al 2002;Costello et al 2005). However, CWC habitat is faced with a number of serious threats including deep sea bottom trawling, cable laying and oil and gas drilling (Fosså, Mortensen and Furevik 2002;Freiwald et al 2004;Gass and Willison 2005).…”

This paper reviews the bioeconomic literature on habitat-fisheries connections. Many such connections have been explored in the bioeconomic literature; however, missing from the literature is an analysis merging the potential influences of habitat on both fish stocks and fisheries into one general, overarching theoretical model. We attempt to clarify the nature of linkages between the function of habitats and the economic activities they support. More specifically, we identify theoretically the ways that habitat may enter the standard Gordon-Schaefer model, and nest these interactions in the general model. Habitat influences are defined as either biophysical or bioeconomic. Biophysical effects relate to the functional role of habitat in the growth of the fish stock and may be either essential or facultative to the species. Bioeconomic interactions relate to the effect of habitat on fisheries and can be shown through either the harvest function or the profit function. We review how habitat loss can affect stock, effort, and harvest under open access and maximum economic yield managed fisheries.
