(2008), Nelson (2006), and Roberts et al. marine fishes caught by bottom, midwater, and surface fishing (2015). An example species image for each family is provided as a methods in New Zealand seas. This revised and updated guide quick visual guide to general body shape. replaces the three-volume set of guides published in 2011 (b) Guide to species (McMillan et al. 2011a-c). Species within each family are arranged alphabetically by It is intended for field use particularly by fisheries observers, scientific name, i.e., by genus name then by species name. Bottom researchers, and fishers who may or may not have specialist and midwater trawl species were selected from records in the knowledge about the taxonomy of fishes. Accurate and rapid Fisheries New Zealand research trawl (trawl) database and the identification of catches at sea is an important pre-requisite for Observer database. obtaining good quality data about fish catches, for monitoring changes in fish abundance and enabling fisheries managers to Selection of the surface species was based on lists of species make informed decisions about fishstock sustainability. given by Griggs et al. (2008) “Fish bycatch in New Zealand tuna longline fisheries in 2005–06”, and Bagley et al.

Field guides are not a substitute for more comprehensive taxonomic guides All known QMS fish species (February 2018) were included and where identification remains uncertain. The most comprehensive the species image for each includes a QMS label in the top right reference for identifying New Zealand fishes is the book “The corner. All protected species likely to be caught by bottom, Fishes of New Zealand”, Roberts et al. (2015), see Key references at midwater, or surface fishing were included and the species image the end of Section 1 below. for each includes a PROTECTED label in the top right corner. An additional group of 54 species included were selected based 2 ORGANISATION OF THE GUIDE on information provided in Roberts et al. (2015), e.g., individual The guide covers 444 species from 152 families, including species of the catshark Apristurus which were previously only hagfishes, cartilaginous (chimaeras, sharks, skates, and rays) and identified to genus. Species were also added based on need, e.g., bony teleost fishes. It includes species that are commonly caught several abundant larger midwater fishes e.g., Dana lanternfish and sold, i.e., “commercial”, as well as those that are not, i.e., “non - (Diaphus danae), were added because recent fisheries surveys commercial”. required routine identification of these species. Taxonomic information, distribution and species codes were The following is provided for each species: updated. Slight changes to the layout enabled the display of two species per page instead of one and resulted in a reduction of the 1. Species common name. These were extracted from the guide from three to one volume. FishNZ database of research species codes, and some additional names were taken from Roberts et al. (2015). There are four main sections. 2. Species scientific name. Updated using Roberts et al. (2015) 1. External features of fishes. Illustrations of some of the essential and Eschmeyer et al.

Family common name. Mostly from Nelson (2006), 3. Guide to species. This section makes up most of the guide, supplemented by Roberts et al. (2015). and includes detailed information for each species. This includes an annotated colour image or line drawing of the fish to illustrate 5. Maori names. These were from Anon (1995) and Strickland distinguishing features; a New Zealand distribution map; and text (1990). Many species may have more than one name covering distinguishing features, colour, size, length measurement depending on the region because iwi (tribes) may use different method, distribution, depth, similar species, and biology and names, and there may also be names for some young stages. ecology. No entry in this field indicates that we were unable to locate a Maori name. 4.
