1. INTRODUCTION. STANDARD TRAMMEL. Figure 1a shows a line segment of fixed length whose ends slide along two perpendicular axes. It can be realized physically as a sliding ladder or as a sliding door moving with its ends on two perpendicular tracks. During the motion, a fixed point on the segment traces an ellipse with one quarter of the ellipse in each quadrant (Figure 1b), so this device is c...

The scalloped spiny lobster Panulirus homarus supports numerous traditional diving, trap and trammel net fisheries in the Western Indian Ocean. Commercial catches made in 2003 to 2005 in the Arabian Sea region of Oman (a coastline of ~1100 km, comprising Dhofar and Al-Wusta) were sampled for length and sex composition, and female reproductive condition. On average, lobsters caught in Dhofar wer...

Abstract Species Distribution Models are pivotal for fisheries management. There has been an increasing number of fishery data sources available, making integration attractive way to improve model predictions. A wide range methods have applied integrate different datasets in disciplines. We focus on the use Integrated (ISDMs) due their capacity formally accommodate types and scale proportional ...

The size selectivity of trammel nets was investigated in the northern Aegean Sea using 10 different inner-panel mesh sizes ranging from 16 to 70 mm nominal (bar length). Selectivity estimates were made for eight most abundant target and bycatch fish species, namely black scorpionfish, Scorpaena porcus Linnaeus, 1758; annular seabream, Diplodus annularis (Linnaeus, 1758); red mullet, Mullus barb...
