Abstract
    The full developmental sequence from egg to juvenile of Gobius paganellus under controlled conditions is described. Embryonic development lasted 9-10 days at 18·5-20·0°C and 10-11 days at 15·0-16·5°C. Newly hatched larvae measured 3·90 mm, had the mouth and anus opened, pigmented eyes and almost no yolk. They first settled 25 days after hatching (10·0-10·5 mm total length [TL]) and showed juvenile behaviour and body form 36 days after hatching (14·0 mm TL). However, they only showed full juvenile pigmentation patterns 15 days later (17·0 mm TL) (16·0-16·5°C). In addition, a preliminary differentiation between the newly hatched larvae of the most common Gobius species of south-western European shores is presented.
