Egg cannibalism in capelin Mallotus villosus at beach and deep‐water spawning habitats in the north‐west Atlantic Ocean
We investigated egg cannibalism in spawning capelin Mallotus villosus on the north‐east Newfoundland coast during July 2012–2014, specifically whether sex, spawning condition ( i.e ., spawning or spent) and spawning habitat influenced egg cannibalism. Capelin spawning in deep‐water were 4.5–14 times...
