Visual census transects were begun in 2001 on Riley’s Hump to enumerate snappergrouper species and determine the effect of enactment of the Ecological Reserve on what were perceived to be overexploited stocks of snapper-grouper species. Our primary concern was mutton snapper, since Riley’s Hump was the site of a historically large spawning aggregation, and anecdotal accounts from fishermen of harvest of mutton snapper from Riley’s Hump during the summer spawning months were of catches in excess of 10,000 lbs of fish per vessel for a four-day trip in the heyday of the aggregation (late 1970s/early 1980s). |

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This work was initiated in July 2001 to document the effect of the newly designated ecological reserve on abundance of snappers and groupers. Two-person dive teams conducted several 30-m visual census strip transects (Brock, 1954) at each station during the summer months of each year, enumerating all species of snappers and groupers observed.The work continued through 2009 over Summer full moon events adding in a benthic cover component using </SPAN><SPAN STYLE="font-style:italic;">in situ </SPAN><SPAN>pictures of quadrats analyzed topside using CPCe.</SPAN></P></DIV></DIV></DIV> |
