Description:

Abstract:

These data consist of larval (< 60 mm) and age-1+ (> 60 mm) Capelin CPUE (Catch per unit effort) from various catch efforts throughout the Gulf of Alaska (GOA) from 1996 – 2017. The dataset contains the following information: fishing gear type, date, time, catch location (latitude and longitude), tow distance, number of capelin caught, and CPUE for capelin greater than and less than 60 millimeters. Gear types include beach seines and trawls.

Purpose:

Dataset was used to help fill in information gaps on capelin spatial patterns and population dynamics. There is limited information on the spatial patterns and population dynamics of capelin in the Gulf of Alaska, but we know that fluctuations in their distribution and abundance occur in response to changes in environmental conditions and that this affects their availability to predators. These data, along with data from other agencies, were used to identify environmental factors associated with areas where capelin consistently occur and concentrate, spatiotemporal trends in capelin abundance, implications for management of the GOA ecosystem, and recommendations for improved monitoring of capelin in the Gulf of Alaska.

Supplemental_Information:

These data were collected during projects funded by the U.S. Geological Survey, Exxon Valdez Oil Spill Trustee Council, and National Park Service. See also Abookire et al. 2005, Arimitsu et al. 2008, Arimitsu et al. 2012, Arimitsu et al. 2016, Arimitsu et al. 2018. Data were compiled from USGS studies conducted within inshore and nearshore waters during summer months (June-August) between 1996 and 2017 in the South central Alaska and Southeast Alaska regions.

Methodology_Description:

U.S. Geological Survey (USGS) inshore surveys. Data were compiled from USGS studies conducted within inshore and nearshore waters during summer months (June-August) between 1996 and 2017 in the SCAK and SEAK regions. Capelin catch per unit effort (CPUE) in beach seines (BS, n = 390), Isaacs-Kidd midwater trawls (IKMT, n = 60), and modified herring trawl sets (MHT, n = 642) was standardized by catch per set for seines, or catch per distance towed (km) for trawls. Fork length (FL) of up to 50 fish from each catch were measured to the nearest 0.1 cm. In 2012 - 2017 total lengths (TL) were converted to FL with the following relationship for length measurements of GOA capelin in seabird diets: FL = 0.944186 x TL – 0.326354 (R^2 = 0.98). Age composition was inferred by size, whereby larval fish were < 6 cm FL, and age-1+ fish were > 6 cm FL. Nets used in sampling capelin include: 1. modified herring trawl - mouth opening 50 meters^2, mesh sizes diminished stepwise from 5 centimeters in the wing to 1 centimeter at the codend, which was lined with 3-millimeter mesh. 2. Isaacs-Kidd Midwater Trawl (IKMT) - A IKMT with a 3-meter depressor bar 3-millimeter mesh and 1-millimeter mesh screen in the codend was used in 2007. In 2008 the net was switched to an IKMT with a 1.8-meter depressor bar with 3-millimeter stretched knotless mesh near the mouth and a 333 µm mesh ring net in the aft section and codend. 3. Beach seine - 37-meters long with diminishing mesh size from 28-millimeters at the wings to 5-millimeters at the center and was set parallel to the shore from a skiff and retrieved from the beach.
