— We examined the potential of North American river otters ( Lontra canadensis ) to buffer the expansion of the invasion by green crab ( Carci-nus maenas ) on the West Coast of the United States, documenting the diet of otters from scat remains on the Wa’atch and Tsoo-Yess Rivers, in Washington State, in 2018 and 2019. We tallied hard remains of prey and calculated frequency of occurrence, and we compared predation of the green crab to monthly values of catch per unit of effort for this crab species. North American river otters did not consume green crab in the Tsoo-Yess River and infrequently consumed green crab in the Wa’atch River (1.66% frequency of occurrence), likely because of the lower abundance of the green crab compared to the abundance of other prey in these rivers. Although our results indicate that North American river otters were not a biotic control of green crab, future studies on the population status of the green crab and North American river otter in both rivers and the long-term predator–prey dynamics could help to better gauge the potential for biotic resistance in populations of the green crab.

— A recent Atlantic- wide tag- recapture experiment run by the International Commission for the Conservation of Atlantic Tunas was an opportunity to directly validate otolith increment deposition rates for bigeye tuna ( Thunnus obesus ) and yellowfin tuna ( T. albacares ) in the region. Age and time at liberty were estimated by using annual and daily increment counts for sectioned otoliths from sampled fish previously injected with oxy- tetracycline and later recaptured. The use of annual increment counts resulted in g reater age estimates than those from daily increment counts for fish >55 cm straight fork length (SFL). Use of daily increment counts led to underestima- tion of time at liberty for fish >55 cm SFL at recovery, compared with known times at liberty. In contrast, predictions based on annual increment counts are accurate across the entire size range of sampled fish, validating the notion that increments are deposited annually. We therefore recommend that counting annual increments be the preferred method for aging yellowfin and bigeye tuna from the Atlantic Ocean and that the use of daily increments for aging be limited to young of the year. Aging fish accurately is important for stock assess- ments in which data on age and growth play an increasingly essential role in examining population dynamics. It is crucial that otolith reading practices and analyses based on age data reflect the most up- to- date recommendations for age estimation.

— Heavy rain can decrease salinity and increase turbidity of the water in coastal areas, negatively affecting the development of organisms, par- ticularly during their early life stages. In this study, the effects of salinity and turbidity on embryos of the bamboo sole ( Heteromycteris japonicus ) were evalu- ated to improve understanding of its tolerance to global climate change. Three experiments were carried out over a 7- d period. In the first experiment, embryos of bamboo sole were exposed for 3 h to 1 of 6 salinity levels (14–34). Low salinity levels (14 and 18) resulted in signifi- cantly shorter total lengths of newly hatched larvae in comparison with larval sizes in treatments with higher salinities, but no significant differences were observed in hatching rate and larval survival rate among treatments. In the second experiment, embryos were exposed to turbidities of 0, 100, 300, 500, and 700 nephelometric turbidity units for 3 h. Turbidity significantly decreased hatching rate, survival rate, and total length and increased onset hatching time and percentage of abnormality. In the third experiment, embryos were exposed to different combinations of salinity and turbidity. The interaction effect of salinity and turbidity on total length of newly hatched larvae was significant. These findings indicate that embryo development of bamboo sole was more affected by
