Sexual dimorphism is characterized by morphological, physiological, or behavioral differences between males and females. The genus Macrobrachium is a diverse group of freshwater shrimps distributed throughout tropical and subtropical regions. They have a great intra- and interspecific morphological variation, with some species showing sexual dimorphism. We investigated the sexual dimorphism of the size and shape of the carapace and body weight of Macrobrachium potiuna (Müller, 1880) in three populations of the State of Paraná through traditional and geometric morphometric techniques. The populations were sampled from three rivers: the Pombas River, Coastal Basin, the Piraquara River, First Plateau, and the Guabiroba River, Second Plateau. Morphometric analyses indicated that male shrimps showed differences in carapace length and body weight: the higher the distance from the sea, the smaller and lighter the shrimps. Carapace shape also differed significantly between the sexes in all three populations, with males having a less robust carapace, but a more elongated rostrum than females. The morphological differences between the genders seem to reflect the reproductive roles of males and females in this environment.

Secondary transport of introduced species can be important in dispersing potentially invasive species, and vectors of transport are often the fouled hulls of small fishing and recreational boats. Likelihood of transport depends on many factors, including resistance of the species to drag forces due to boat velocity and resistance to desiccation. To experimentally test the importance of drag on transport, we attached plates with a preexisting, 4 months old, assemblage of species, on a boat hull that was then subjected to one of three speeds (5, 15 and 20 knots) for 20 min. We experimentally tested desiccation tolerance with colonized plates that were exposed to the air for 3–132 h, after which they were examined for living organisms. A total of 35 taxa were identified, including introduced species, in southern Brazil: the barnacles Amphibalanus amphitrite, A. reticulatus and the octocoral Stragulum bicolor. In the drag experiment, all species survived transport. In the desiccation experiment, most species survived more than 6 h (fewer species much longer) of exposure to the air. Our results illustrate that a variety of taxa and growth forms can be transported over regional scales at speeds and travel conditions typical of small boats. They can also survive desiccation conditions typical of overland transportation of small boats. Thus, we recommend that additional management mechanisms must be put in place to reduce the probability of invasion due to secondary transport.

The objective of this study was to evaluate the effect of stocking densities on productive performance of the freshwater prawn Macrobrachium rosenbergii in biofloc system. Experimental tanks (microcosms) with 0.20 m² area were used as experimental units. The tanks were connected to two 300 L matrix tanks (macrocosm) with biofloc technology, used as recirculating units. M. rosenbergii juveniles, with an initial weight of 0.315 ± 0.06 g and initial length of 33.34 ± 2.26 mm, was randomly distributed in the experimental tanks at different stocking densities (50, 100, 150, 200 and 250 ind m-²) and reared during 60 days. The total biomass at the end of the experiment was significant higher ( P < 0.05) with the use of higher stocking density (250 ind m -² ). However, prawns stocked at the density of 50 m -² showed significant higher ( P < 0.05) survival (73%) and significantly lower values (P < 0.05) for feed conversion rate (1.28). The different stocking densities evaluated did not affect the weight and length of prawns. The recommended density for growing M. rosenbergii in the biofloc system is 50 ind m -² .
