Freshwater turtle populations are susceptible to declines following small increases in the mortality of adults, making it essential to identify and understand potential threats. Freshwater turtles ingest fish hooks associated with recreational angling, and this is likely a problem because hook ingestion is a source of additive mortality for sea turtles. We used a Bayesian-modeling framework, observed rates of hook ingestion by freshwater turtles, and mortality of sea turtles from hook ingestion to examine the probability that a freshwater turtle in a given population ingests a hook and subsequently dies from it. We used the results of these analyses and previously published life-history data to simulate the effects of hook ingestion on population growth for 3 species of freshwater turtle. In our simulation, the probability that an individual turtle ingests a hook and dies as a result was 1.2-11%. Our simulation results suggest that this rate of mortality from hook ingestion is sufficient to cause population declines. We believe we have identified fish-hook ingestion as a serious yet generally overlooked threat to the viability of freshwater turtle populations.

“…Manatees occupy both freshwater and coastal marine environments and sport fishers encroach on both environments, increasing the chance of this species' interaction with derelict gear. Globally there has been an increase in sport fishing and results from Adimey et al (2014) showed that monofilament lines and hooks are the main debris that manatees interact with, either through ingestion or entanglement. However, there is not yet enough evidence to suggest that hook and line is the only significant type of ALDFG posing a risk to this species.…”

“…The impacts of marine litter on marine life and the environment include deviation in epi-benthic community structure and composition (Katsanevakis et al, 2007); entanglement of organisms especially in derelict fishing gear and 'ghost nets' (Waluda and Staniland, 2013;Adimey et al, 2014;Anderson and Alford, 2014) and ingestion (Goldstein and Goodwin, 2013;Lusher et al, 2013;Anastasopoulou et al, 2013;Bond et al, 2013;Madeira Di Beneditto and Arruda Ramos, 2014). In addition floating litter facilitates the migration of non-native species to other marine regimes.…”

In the present work, abundance, spatial distribution and qualitative composition, of benthic marine litter, were investigated in five study areas from the Eastern Mediterranean and Black Seas (Saronikos, Patras and Echinades Gulfs; Limassol Gulf; Constanta Bay). Surveys were performed using the monitoring protocol proposed by the Technical Group for Marine Litter. Densities ranged from 24items/km(2) to 1211items/km(2), with the Saronikos Gulf being the most affected area. Plastics were predominant in all study areas ranging from 45.2% to 95%. Metals and Glass/Ceramics reached maximum values of 21.9% and of 22.4%. The size distribution of litter items showed that ⩾50% fall into medium size categories (10×10cm, 20×20cm) along with an elevated percentage of small-sized (<5×5cm) plastic litter items. The comparative analysis of the data highlighted the dependence of the marine litter problem on many local factors (human sources and oceanographic conditions) and the urgent need for specific actions.
