Paul, and William Rugen ABSTRACT: Structures on the otoliths of arrowtooth flounders Atheresthes stomias have been identified that correspond with hatching and settlement. Analysis of length frequency profiles and back-calculation of otolith dimensions suggested that arrowtooth flounders hatch at a mean standard length (SL) of 8–9 mm. They are planktonic for 145 d, and become benthic at 40–43 mm SL. Averaged over 14 years, the mean dates for hatching and settlement were April 15 and September 8, respectively. The hatch and settlement periods were protracted, with a 95% prediction interval (PI) of 37 days for each period. This wide 95% PI in hatch and settlement dates is a function of a long hatching period, not year-to-year fluctuations in hatch date. INTRODUCTION tions may temporarily disrupt energy and nutrient flow, leaving an identifiable growth discontinuity on the otolith.

1 Students Look at Images of Fish Caught by an Otter Trawl Net Off
BIOGEOGRAPHY OR WHAT HAPPENS TO FISH POPULATIONS DURING EL NIÑO OVERVIEW Students look at images of fish caught by an otter trawl net off southern California. Using fish charts provided in this activity, they identify the fish and record their geographic range. The fish were collected in May 1997, shortly after the beginning of a major El Niño event. Students see what effects the El Niño had on fish population during its early stages. CONCEPTS • In a given area fish populations can change as water conditions (e.g., temperature) change off- shore due to El Niño effects. • Effects of an El Niño occur over time, so the U.S. west coast may not show significant effects for several months after an El Niño begins developing in equatorial waters. MATERIALS • Movie of fish catch included with this activity (activity can be done without the movie) • Fish Keys (included) • “Catch of the Day” sheet (included) • Paper and pencil to record results • Atlas or map with geographical information about the U.S. west coast (if needed) PREPARATION Divide students into small groups. Make copies of Fish Key and Catch of the Day sheets, one for each group. PROCEDURE Engagement An El Niño event is thought to be triggered when steady westward blowing trade winds weaken and even reverse direction. This change in the winds allows the large mass of warm water that is normally located near Australia to move eastward along the equator until it reaches the coast of South America. It then spreads out along the western coasts of the Americas, affecting water temperatures and weather patterns. -

However, traditional DNA sequencing methods are slow, expensive, and 14 require well-equipped laboratories. We here test whether these problems can be 15 overcome through the use of Nanopore sequencing. We sequenced 92 single and 13 16 mixed-species samples bought in supermarkets and restaurants in Singapore which has a 17 large and diverse seafood trade. We successfully obtained DNA barcodes for 94% and 18 100% of the single- and mixed-species products after correcting the numerous 19 sequencing errors of MinION reads with a correction pipeline optimized for DNA 20 barcodes. We find comparatively low levels of clear-cut mislabelling for single-species 21 samples (7.6 %) while the rates are higher for mixed-species samples (38.5 %). -
Change in Oregon's Nearshore Groundfish Trawl Fishery
AN ABSTRACT OF THE THESIS OF Rebecca A. Howard for the degree of Master of Science in Marine Resource Management presented on September 9, 2020. Title: Change in Oregon’s Nearshore Groundfish Trawl Fishery: Perspectives from Science and Industry Data. Abstract approved: _____________________________________________________________ Lorenzo Ciannelli The commercial groundfish fishing industry and groundfish research have a long concurrent history of activity on the Oregon continental margin. Within the non-whiting groundfish fishery, the target species are primarily flatfishes, sablefish, lingcod, and rockfishes, though landings of each have fluctuated over time. Recent work shows that over the past two decades, fishing effort has shifted offshore likely due to implementation of gear regulations, area closures, and lower catch limits. Although federal fishery-independent surveys have been conducted across most of the groundfish fishery’s depth range, data is limited by years and seasons surveyed as well as absence of data in the shallowest waters (< 55 m). Fishery-dependent data covers those shallow waters and a broader temporal range, but at a coarse scale. Limitations in data coverage combined with a historical focus on deep-water groundfishes has led to a gap in understanding of dynamics within the nearshore fishery, particularly regarding the influence of environmental factors on abundance and distribution. Through this thesis, I analyzed changes in spatiotemporal dynamics of the Oregon nearshore non-whiting groundfish trawl fishery and assessed gaps in each data source over the past four decades. Statistical modeling was used to elucidate distribution shifts in species as well as temporal changes in community composition. These analyses revealed how individual species’ distributions have geographically shifted over time, what environmental variables affect their spatial distribution, and how depth and habitat type strongly influence nearshore community composition.
