Understanding and managing fish populations: keeping the toolbox fit for purpose.

Wild fish populations are currently experiencing unprecedented pressures, which are projected to intensify in the coming decades. Developing a thorough understanding of the influences of both biotic and abiotic factors on fish populations is a salient issue in contemporary fish conservation and management. During the 50th Anniversary Symposium of The Fisheries Society of the British Isles at the University of Exeter, UK, in July 2017, scientists from diverse research backgrounds gathered to discuss key topics under the broad umbrella of 'Understanding Fish Populations'. Below, the output of one such discussion group is detailed, focusing on tools used to investigate natural fish populations. Five main groups of approaches were identified: tagging and telemetry; molecular tools; survey tools; statistical and modelling tools; tissue analyses. The appraisal covered current challenges and potential solutions for each of these topics. In addition, three key themes were identified as applicable across all tool-based applications. These included data management, public engagement, and fisheries policy and governance. The continued innovation of tools and capacity to integrate interdisciplinary approaches into the future assessment and management of fish populations is highlighted as an important focus for the next 50 years of fisheries research.

What pediatric home care offers the nurse.

Pammy had never been home in her 16 months of life. She'd never been in a car seat, seen her sister go off to school, or sat outside in her stroller. Today was the first day of a new life. While her Dad finished putting the crib together and the respiratory therapist arrived with the missing ventilator connector, her mother and her nurse Judy were accompanying her in the ambulance home. Soon her tube-feeding bag was hanging on a hook next to the "Welcome Home, Pammy" sign that a neighbor had made on his computer, and her four-year-old brother was building a runway under the nurse's feet. The back-up ventilator filled a quarter of the small living room, and the tubing, suction catheters, vent parts, formula, and water bottles filled the closet in Pammy's room--large enough because Mom and Dad had moved out of the master bedroom. Judy had helped Pam's mother set up the room a week ago and already had a sense of her concerns, the four-year-old's busyness, and the irregular schedule that the father worked. This would be an enjoyable, but challenging experience.

Home care protocols for pediatric tracheostomy patients.

Pediatric tracheostomy patients can present a challenge to their families and the nurses who care for them, but careful planning and an eye toward the future turns the challenge into a reward.
