Fig. 1. Macrobrachium miyakoense Komai & Fujita, 2005, adult male (pocl 18.9 mm) from Miyako Island, Ryukyu Islands, Japan (RUMF- ZC-2665). A, rostrum, carapace, and cephalic appendages, lateral view; B, eye (left side), ventral view (left), dorsal view (right); C, left second pereiopod, lateral view; D, same, chela (setae and spinules omitted); E, same, basal part of fingers, dorsal view; F, right second pereiopod, lateral view; G, same, basal part of fingers, dorsal view. Scale bars = 1.0 mm.
Figure 5 in Influence of color and brightness on ontogenetic shelter preference by the prawn Macrobrachium rosenbergii (Decapoda: Palaemonidae)
Figure 5. Preference for shelters of different colors by juvenile and adult prawns. The bars represent the number of records of occupancy for each shelter. Black bars represent shelters that were chosen significantly above the expectancy level. Grey bars represent shelters chosen at expected frequencies. The white bar represents a shelter chosen significantly below expectancy levels.
Figure 4 in Influence of color and brightness on ontogenetic shelter preference by the prawn Macrobrachium rosenbergii (Decapoda: Palaemonidae)
Figure 4. Chromaticity-luminance diagram for the visual system of prawns. Inferred chromatic and achromatic signals, determined for a perfectly white surface (asterisk depicted in the diagram) and for shelters employed in our experiments (squares), are represented. Distance between squares indicates color and brightness differences in chromatic and achromatic signal axes, respectively. Short λ = short wavelengths (e.g. blues), Long λ = long wavelengths (e.g. yellows).

Figure 2 in Influence of color and brightness on ontogenetic shelter preference by the prawn Macrobrachium rosenbergii (Decapoda: Palaemonidae)
Figure 2. Reflectance spectra of experimental shelters. The reflectance of each curve is represented as a percentage, compared to the maximum reflectance of the most reflective curve. Each curve is represented approximately the same color as the respective shelter.
Figure 1 in Influence of color and brightness on ontogenetic shelter preference by the prawn Macrobrachium rosenbergii (Decapoda: Palaemonidae)
Figure 1. Schematic view of the arrangement of shelters in an experimental aquarium. The prawns were individually tested in aquaria with 10 colored shelters arranged in two rows of five.

Data from: Elasmobranch bycatch in the demersal prawn trawl fishery in the Gulf of Papua, Papua New Guinea
The elasmobranch bycatch of the Gulf of Papua Prawn Fishery is investigated in detail for the first time. Fisheries observers collected data on the elasmobranch bycatch from a total of 403 trawl sets (1,273 hrs) in the Gulf of Papua. A total of 40 species of elasmobranchs were recorded ranging in size from a 12 cm disc width stingray to a 350 cm total length sawfish. High mortality rates were recorded (>80%), attributed to the long trawl durations (up to 4 hours). The future inclusion of bycatch reduction devices would likely reduce the number of larger elasmobranchs being caught and is being investigation by the PNG National Fisheries Authority. Differences in catch compositions were detected across the management zones as well as between the two monsoonal seasons (SE Monsoon and NW Monsoon). Increased monitoring and additional research is required and management plans should address the elasmobranch bycatch and in particular their high mortality rate.
