| In Curacao, deep-water fads with grp surface buoys were developed and tested. The first fad was deployed in 1993. Up to now, a total of 5 fads were deployed at the following depths: 730, 685, 700, 754 and 574 metres. Changes were made to the surface buoy, resulting in an improved design, the mkii surface buoy. One fad lasted three years and one month. The main features of the design used are: the use of a sparbuoy design with constant tension on the moving chain to avoid slamming and jerking of the surface buoy; liberal use of sacrificial anodes, and maintenance to replace these anodes about once a year; the use of a short anchor chain with depth buoys, that does not touch bottom; a one-piece inverted mushroom anchor. With the grp surface buoy, a reserve... |

| Recently discovered crabs from the Middle to Upper Eocene of northern Bonaire, Netherlands Antilles, include well-preserved carapaces of Montezumella rutteni Van Straelen, originally described from an incomplete holotype. The more comprehensive description of this species provided herein includes documentation of the first attributable left cheliped of Montezumella. From the same locality, Ocalina sublevis sp. nov. considerably extends the known geographic range of this genus. Both of these Tethyan decapod genera apparently migrated west from the Mediterranean region during the Eocene. Despite these new determinations, decapod crustaceans remain poorly known from the Eocene of the Antillean islands. Additionally, Callianassa pustulosa Withers from the... |
