Comparing catch efficiency of five models of pot for use in a Newfoundland and Labrador cod fishery.

ABSTRACT: Sustainability of commercial fisheries is best achieved when fishing gears are selective and have low impacts on bottom habitat. Pots (baited traps) are a fishing technology that typically has lower impacts than many other industrial gears. In this study we compared the efficiency of five models of pots (baited traps) designed to catch Atlantic cod (Gadus morhua) for use in Newfoundland and Labrador (NL)'s expanding cod fishery. We compared catch per unit effort (CPUE) and total lengths of cod across each pot type, as well as bycatch rates of each model. All pot types were successful at catching cod, but two models (the modified Newfoundland pot, and a four-entrance pot of our design) had highest CPUE. Specifically, we found that modifying Newfoundland pots increased their CPUE by 145% without a corresponding increase in bycatch. None of the pot types produced substantial amounts of bycatch. This study demonstrated that potting gear is an effective way to catch cod in NL, and that there is flexibility in which pot fishers can use, depending on the layout of their fishing vessel.

Project description:Mothers have a significant influence on family dynamics, child development, and access to family services. There is a lack of literature on the typical Canadian maternal experience and its influence on access to services for mothers despite recognizing the importance of mothers. A cross-sectional study was conducted to address this research gap that employed Andersen's Behavioral Model of Health Service Use in conjunction with a feminist lens. A total of 1,082 mothers who resided in Newfoundland and Labrador (NL) participated in a province-wide survey in 2017 and reported on their wellbeing, family life, and healthcare utilization. Stepwise binomial logistic regressions and linear regressions were used to predict initiation and continued service utilization within the preceding 12 months, respectively. Mothers who participated in this survey were older, and were more likely to be in a relationship than those in the Canadian census, while no difference was observed in annual income. Approximately half of mothers accessed services for themselves over the previous 12-months, with the overwhelming majority accessing services for their children. Medical services were the most likely to be utilized, and mental health and behavioural services were the most likely services to be needed, but not available. Sociodemographic (e.g., age, education attainment), familial relationships and role satisfaction, health need, and health practices predicted maternal initiation and continued use of services, with a larger number of variables influencing maternal service initiation as compared to continuous use of services. Sociodemographic (e.g., maternal age, community population), maternal social support, health need, and maternal health practices predicted maternal access of at least one child service while family relationships, health need, and maternal health practices predicted maternal use of a range of child services conditional on initial access. These results can support the provincial health system to better support access to care by acknowledging the interdependent nature of maternal and child health care utilization. They also highlight the importance of equitable healthcare access in rural locations. Results are discussed in terms of their clinical relevance to health policy.
