| Collecting Event Remarks | Water temp. = 26 C. Males in nuptial coloration were extremely abundant. Gravid females were extremely abundant. Adult stickleback and small fry were extremely abundant. However, intermediate fish were very rare. Green heron seen landing at edge of lagoon. This is a marine estuary. It is choked in the areas seined with aquatic grass. It appears that the sticklebacks were breeding at the edges of the grass because most adult fish were seined in these areas and almost all fish were either nuptially colored males. Males with post-nuptial melanism or large females of which were gravid. Small sticklebacks were very abundant, especially within the grass. Also caught Eucyclogobius newberri. | ||||||
