This paper reports on the length-weight relationships of ten teleost fish species inhabiting seagrass meadows constituted by the marine angiosperm Cymodocea nodosa from the Canary Islands (North-eastern Atlantic): Bothus podas, Xyrichtys novacula, Mullus surmuletus, Sparisoma cretense, Diplodus annularis, Pagellus erythrinus, Spondyliosoma cantharus, Syngnathus typhle, Canthigaster capistrata and Sphoeroides marmoratus. A total of 1,396 individuals were collected using a seine net. These equations represent the first biological data for C. capistrata and S. marmoratus throughout their distribution range, as well as the first length-weight relationships for B. podas, X. novacula, S. typhle, C. capistrata and S. marmoratus from the study region, and they will be a useful tool to increase the ecological knowledge of these species.
