| Abstract |
Adult pinfish, Lagodon rhomboides, were collected during September and October, 1974 and 1975. Following a minimum of one week holding period, females were initially injected with 200 IU human chorionic gonadotropin and injected with 400 IU every second day thereafter until mature ova (0.90-0.93 mm diameter) were produced. Ova were artificially fertilized and the embryonic period (sensu Balon, 1975) described and illustrated. Emergence occurred 48 hr after fertilization at 18C and eye pigmentation appeared 144 hr after fertilization. Larval total length at emergence was 2.3 mm; at 96 hr post-emergence, 2.7 mm; and at 120 hr post-emergence, 2.5 mm. Decrease in length and death of larvae after 96 hr post-emergence was probably due to malnutrition and subsequent infection. |
