The data in the files of this dataset represent the raw and standardized information of the distribution of the number of prey in stomachs of larval fish, the increments widths derived from larval fish, and the mortality rates, that were included in the study by Pepin (2024) into the probability distribution of larval fish vital rates. Data were collected from different surveys and process-oriented investigations conducted in coastal Newfoundland, Canada, as part of a number of studies into the ecology of the ichthyoplankton community (Supplementary material Tables S1-S3). Field work was carried out between April and September, with most collections taking place from June to August, in three deep bays along the east coast of Newfoundland (Bonavista Bay: 48°45′N, 53°20′W; Trinity Bay: 48°00′N, 53°30′W; Conception Bay: 47°45′N, 53°00′W). Larval fish were collected using either a ring net (0.75m diameter, 165 µm mesh; Pepin and Penney (1997)), bongo nets (0.6m diameter, 333 µm mesh), or a 4 m2 variable-mesh Tucker trawl (333, 570 and 1000 µm mesh; ) towed at 1.5 m s-1. Samples were preserved in 4-5% buffered formaldehyde, or in 95% ethanol for otolith-based estimation of growth…
