Abundance estimates are essential for fisheries management, but estimating the abundance of open populations with low recapture rates has historically been unreliable. However, by using mark-recapture data modulated with survivability parameters obtained from analysis of acoustic telemetry data, more accurate abundance estimates can be made for species that exhibit these characteristics. One such species is the Atlantic sturgeon, for which abundance estimates were designated a research priority following precipitous population declines throughout the 20th century. We addressed this research need in the Saco River Estuary (SRE), a system where the Atlantic sturgeon has been extensively studied using mark-recapture and acoustic telemetry methods since 2009. These data were analyzed using Bayesian analysis of a Lincoln-Peterson estimator, constrained with parameters from a Cormack-Jolly-Seber model, to provide an initial abundance estimate for the system. The resulting estimate indicated that approximately 3 299 (95% Credible Interval: 1 462–6 828) Atlantic sturgeon utilize the SRE yearly, suggesting that the SRE provides critical foraging habitat to a large contingent of the species within the Gulf of Maine. The present study demonstrated the method utilized herein was effective in generating a reasonable estimate of abundance in an open system where recapture events are rare, and therefore may provide a valuable technique for supplying initial estimates of fish abundance in additional systems that display similar characteristics.

This study examined the traditional knowledge of fishermen at Mamirauá Reserve about sex determination of pirarucus, Arapaima gigas Schinz 1822. We evaluated the criteria used for by fishermen in the sector Jarauá at Mamirauá Reserve for this determination, during the fisheries season, from October to November 2004. We analyzed responses of a group of about 15 fishermen collected in structured interviews regarding 109 individual pirarucus, 65 males and 44 females. From this sample, only 64 fish have their sex correctly predicted by the fishermen. Although the traditional knowledge of local fishermen is a key component of the sustainable fisheries of this species, this knowledge is not functional in all ranges and aspects, as in sex distinction. We found that the local fishermen evaluated are not able to recognize the sex of pirarucus, although some criteria applied for this purpose are consistent with their biology. The rates of correct forecasts for recognition of males and females were similar to those obtained by chance, even when the criteria applied were consistent, as the criterion “coloration”, which was significantly consistent for identification of males. Yet the group of fishermen interviewed in this study apparently did not apply this criterion correctly.
