Abstract Deep-water brachyuran crabs collected from the Indian Exclusive Economic Zone by the Fishery Oceanographic Research Vessel “Sagar Sampada” in the southeastern Arabian Sea (50 m depth), southwestern Bay of Bengal (307 m depth), and in the vicinity of the Andaman and Nicobar Archipelagos (271-535 m depth) were studied. They are referred to Sphaerodromia kendalli (Alcock and Anderson, 1894) and Sphaerodromia nux Alcock, 1900 (family Dromiidae), Intesius brevipes sp. nov. (family Mathildellidae), Tunepugettia corbariae B.Y. Lee, Richer de Forges and P.K.L. Ng, 2019 (family Epialtidae), Cyrtomaia suhmii Miers, 1885 (family Inachidae), Chaceon alcocki Ghosh and Manning, 1993 (family Geryonidae), and Sphenomerides trapezioides (Wood-Mason, 1891) (family Trapeziidae). Sphaerodromia nux and T. corbariae are new records from Indian waters. The first male specimen of C. alcocki is reported, with a description of the male first gonopod. Intesius brevipes sp. nov. is the fifth species of the genus, differing from the four known congeners in the form and setation of the carapace, distinctly curved and granular anterolateral margins, and shorter pereopods with much slender merus and carpus articles.

Abstract Understanding the upstream migration of amphidromous prawns is important to address the impact of anthropomorphic activities in natural freshwater ecosystems. The ability of Macrobrachium tenellum (Smith, 1871) juveniles to overcome an artificial barrier was evaluated, simulating an obstacle in their upstream migration, under an experimental laboratory system. The prawns were collected from a stream located in Puerto Vallarta, Mexico (N = 1000). An experimental recirculation system was used, which consisted of a tank with a capacity of 600 L, a sheet of galvanized steel that acted as an anthropogenic barrier and two submersible electric pumps with flows of 0.12 L/s and 0.40 L/s. In this system, two inclinations of the barrier were tested, 45° and 90° in combination with the two flows. The results show that there are significant differences between the treatments with different inclinations, where a higher stimulation response was observed at the 90° angle. Within this inclination, the flow of 0.40 L/s produced the highest stimulation to climb the barrier in prawns between 30 and 60 mm in length. This study demonstrates the direct relationship between the slope and the effect of water flow of the anthropogenic barriers that hinder the migration process of M. tenellum.

Abstract Amphipods of the family Phoxocephalidae G.O. Sars, 1891 collected by the R/V Almirante Saldanha off the coast of Uruguay and Argentina in 1972 were examined. New records from the northern Argentine Sea and Uruguayan Sea include two species of the subfamily Harpiniinae Barnard and Drummond, 1978: Pseudharpinia jonesyi Andrade and Senna, 2020a, previously known from southeast/southern Brazil; and Pseudharpinia tupinamba Senna and Souza-Filho, 2011, recorded hitherto only from southeastern Brazil. Six species of the subfamily Phoxocephalinae G.O. Sars, 1891 were also recorded: Fuegiphoxus abjectus Barnard and Barnard, 1980, Fuegiphoxus fuegiensis (Schellenberg, 1931), Metharpinia dentiurosoma Alonso de Pina, 2003b, Metharpinia grandirama Alonso de Pina, 2003b, Metharpinia protuberantis Alonso de Pina, 2001, and Parafoxiphalus longicarpus Alonso de Pina, 2001. Redescriptions and discussion on distribution and morphological variations are presented.

Abstract The present study investigates the spatio-temporal variation in the density of the adults and larvae of the shore crab Pachygrapsus gracilis and identifies the reproductive period and the population structure of the species in the Marapanim estuary, in northern Brazil, in order to describe the biological characteristics of this equatorial population on the Atlantic coast. Specimens were collected manually every month over the course of a year. Adults were collected at four rocky outcrops in the upper and lower mid-littoral. Larvae were sampled at six points using horizontal trawls of the surface water. The sampling points represent the inner and outer estuary, its two margins, and varying gradients of salinity. The density of the zoea I and adults were higher on the margins with the highest sediment deposition rates and salinity. Only the density of the adults correlated significantly with salinity. Although ovigerous females were only collected in the rainiest periods, the presence of juveniles throughout the year indicates that the species reproduces continuously. The population parameters indicate that the density of P. gracilis was related to salinity, and that part of the life cycle of these crabs is completed in the Marapanim estuary. This species reproduces in the estuary, exports zoea I to the coastal waters and then probably returns as megalopae, responding to local conditions through systematic shifts in its distribution and abundance over time and space. The population was relatively stable and able to adjust to the considerable variation in abiotic factors that are typical of this estuary.

Abstract Crustacean decapod larvae have developed several adaptations to maximize their survival, including swimming behavior. Swimming improves larvae dispersal and contributes to their response to environmental stresses, including variations in abiotic factors, presence of predators, and search for food. Data on larval behavior can also assist in studies on conservation and in species management in aquaculture. Unfortunately, swimming behavior remains unstudied in many species. The present work aims to analyze the swimming behavior in newly hatched larvae of six common decapod crustaceans in coastal Southeast Brazil (Macrobrachium acanthurus, Macrobrachium olfersii, Emerita brasiliensis, Ucides cordatus, Minuca rapax, and Callinectes danae). The analysis included tests with larval responses to four isolated stimuli: gravity (geotaxis), vertical salinity gradients, low-pressure zones, and presence of the planktivorous fish, Atherinella brasiliensis (only for C. danae and M. rapax). The first two and the last two stimuli were used as indicators of dispersal and defensive behaviors, respectively. All larvae preferred water depth with higher salinity levels. Additionally, negative geotaxis was observed in M. olfersii, M. acanthurus, U. cordatus, and C. danae, being stronger in the last. Both Macrobrachium larvae responded to low-pressure zones, promptly moving away. Callinectes danae and M. rapax larvae avoided contact with the predatory fish by creating avoidance zones around it, even in the absence of light. This is an active defensive behavior that has never been reported for the newly hatched larvae of these two species.
