James H. Selgeby 1988 <p><span>The slimy sculpin (</span><i>Cottus cognatus</i><span>), spoonhead sculpin (</span><i>Cottus ricei</i><span>), and deepwater sculpin (</span><i>Myoxocephalus thompsoni</i><span>) are abundant fishes in Lake Superior. Slimy and spoonhead sculpins occupy a zone from near shore to depths of 210 m but are generally most abundant in waters 50 to 90 m deep. Deepwater sculpins are found in waters from 15 to 407 m deep and are most abundant at depths greater than 70 m. All three species of sculpins eat mainly burrowing amphipods (</span><i>Pontoporeia affinis</i><span>) although deepwater sculpins also eat substantial quantities of opossum shrimp (</span><i>Mysis relicta</i><span>). The three sculpins grow at similar rates. Among the fishes aged, the maximum age of slimy sculpins was 5 years, compared with 6 years for spoonhead sculpins, and 7 years for deepwater sculpins. Indirect evidence indicates that slimy and spoonhead sculpins spawn in the spring, and deepwater sculpins spawn in midwinter.</span></p> application/pdf 10.1016/S0380-1330(88)71531-2 en Elsevier Comparative biology of the sculpins of Lake Superior article
