Crustacean Fauna of a Mussel Cultivated Raft System in the Black Sea
Arthropods, 2013, 2(2): 89-94 Article Crustacean fauna of a mussel cultivated raft system in the Black Sea Murat Sezgin, Eylem Aydemir Çil Sinop University Faculty of Fisheries Department of Marine Biology and Ecology TR57000 Sinop, Turkey E-mail: [email protected] Received 1 January 2013; Accepted 5 February 2013; Published online 1 June 2013 Abstract The aim of the current study was to make a faunistic analysis of the crustaceans associated with cultivated mussels grown on ropes. Mussel samples from 30 cm ropes were collected from rope-grown mussel beds by hand. The crustacean fauna associated with mussel population were quantified. The density of crustacean fauna associated with mussels was significantly greater within rope-grown mussel assemblages than on other biotopes around.

The biodiversity associated with cultivated mussel assemblages depends partly on the source of the mussels and on the new habitat created by the method of cultivation. To date, no study has been made of the macrofauna associated with mussels in the habitats created by different methods of mussel cultivation in the Black Sea. -

Are Marine Isopods Picking Favorites with Colors? the Role of Color Sensing in Food Preference in Pentidotea Wosnesenskii
Are marine isopods picking favorites with colors? The role of color sensing in food preference in Pentidotea wosnesenskii Aurora Nelson1,2 Friday Harbor Labs FHL 470 A Research in Marine Biology Spring 2021 1 Friday Harbor Laboratories, University of Washington, Friday Harbor, WA 98250 2 Department of Marine Biology, University of Washington, Seattle, WA 98195 Contact information: Aurora Nelson [email protected] Keywords: marine isopod, Pentidotea wosnesenskii, color sensing, chromatophores Nelson 1 Abstract The marine isopod Pentidotea wosnesenskii is one of many species that can change its color throughout its life. The variety of colors it can take on allows it to match the species of algae it lives on and consumes. While this isopod can change its color when moved to a new substrate, this requires it to build a new cuticle and molt, a process that takes weeks. It seems likely that it would be more efficient for an isopod to seek out algae that it is already matched to. This species is highly likely to have color sensing abilities as a way of adjusting their chromatophores, so they may use those abilities to search for a substrate that they can match. I placed isopods in containers where they had access to three different colors of algae. I hypothesized that adult isopods would show a preference for algae that was similar in color to their cuticles. However, the results of this study do not suggest that isopods use color sensing to move to matching backgrounds. Instead, they may be choosing substrates based on its quality as a food source or how well they can attach themselves to it. -

A marine isopod, S. laevidorsalis must be submerged in water to breathe. S. laevidorsalis grows to about 3 cm in length and can be found on docks and pilings among seaweed and hydroids. This isopod is classified as an omnivorous scavenger, eating both dead and living material, particularly hydroids. The camouflage pattern on its body allows it to blend in with its environment, and the tiny claws on each leg help it cling to surfaces. -
Chapter 8 Benthic Assessment of Marine Areas of Particular
Chapter 8 Benthic assessment of marine areas of particular ecological importance within the German Baltic Sea EEZ Michael L. Zettlera and Fritz Gosselckb a Baltic Sea Research Institute, Rostock b Institute for Applied Ecology, Broderstorf Abstract The Habitats Directive is one of the main legal tools of the European Union to preserve biodiversity by maintaining and restoring natural habitats, and establishing a network of protected sites (NATURA 2000). One point of interest is the characterisation of marine habitats to localise the areas that fulfil the protection targets. Of the habitats listed in Annex I of the Habitats Directive, mainly reefs and sandbanks are relevant in the case of German Baltic offshore waters. Along a strong salinity gradient (5 to 25 psu), four planned offshore Marine Protected Areas (MPAs) within the German Exclusive Economic Zone (EEZ) of the Baltic Sea were thoroughly investigated in this study. More than 250 locations were analysed using a combination of standard sampling methods, underwater video technique, and measurement of abiotic factors (salinity, oxygen, sediment parameters). The areas of interest were the Odra Bank (Oderbank), Adler Ground (Adlergrund), Kadet Trench (Kadetrinne), and Fehmarn Belt (Fehmarnbelt). The characteristic living communities (macrophytes, such as algae and sea grass, and macrozoobenthos such as worms, bivalves and crustaceans) for the different habitat types in these areas were characterised. Due to different salinity regimes, the benthic colonisation is different as well. In the Baltic Sea, with its decreasing salinity from west to east, the number of marine species declines, too. In the present study, altogether approximately 350 macrozoobenthic species and approximately 20 macrophytes were identified. -
Invertebrate ID Guide
11/13/13 1 This book is a compilation of identification resources for invertebrates found in stomach samples. By no means is it a complete list of all possible prey types. It is simply what has been found in past ChesMMAP and NEAMAP diet studies. A copy of this document is stored in both the ChesMMAP and NEAMAP lab network drives in a folder called ID Guides, along with other useful identification keys, articles, documents, and photos. If you want to see a larger version of any of the images in this document you can simply open the file and zoom in on the picture, or you can open the original file for the photo by navigating to the appropriate subfolder within the Fisheries Gut Lab folder.
