Higher temperatures increase developmental rate & reduce body size at hatching in the small-eyed skate Raja microocellata: implications for exploitation of an elasmobranch in warming seas
Effects of temperature on development of Raja microocellata was tested by maintaining embryos in controlled conditions representative of those predicted under current climate scenarios. There was a positive relationship between size of neonates & developmental rate: temperatures 14.5-16.5 degrees C produced skates 3.5-7%, respectively, smaller than those raised at 12.5 degrees C. Developmental rates were also 12-23% faster, with neonates hatching 3-7 weeks earlier.
