We evaluated 19 traditional (K, Kn, hepatosomatic index, gonadosomatic index, energy density and percent dry 20 weight of muscle [%DWM] and liver [%DWL]) and newer (bioelectrical impedance analysis 21 [BIA] and scaled mass index [SMI]) condition indices to track seasonal cycles in three 22 flatfishes– winter (3 stocks), yellowtail (3 stocks), and summer flounder (1 stock) –with 23 contrasting life histories: in habitat, feeding, and reproduction. The %DWM and %DWL were 1 https://mc06.manuscriptcentral.com/cjfas-pubs Canadian Journal of Fisheries and Aquatic Sciences Page 2 of 64 24 good proxies for energy density (r2 > 0.96) and more strongly related to K, Kn and SMI than to 25 BIA metrics. Principal component analysis indicated many metrics performed similarly across 26 species; some confounded by size, sex, and maturity along PC1, others effectively characterizing 27 condition along PC2. Stock differences were along PC1 in winter flounder, reflecting different 28 sizes across stocks, whereas in yellowtail flounder differences occurred along PC2 related to 29 condition. These comparisons, within and across species, highlight the broad applicability of 30 some metrics and limitations in others. 31 32 Introduction 33 The physiological health and energetic status of fishes is increasingly evaluated for a broad range 34 of purposes; as a proxy for reproductiveDraft output (Marshall et al. 1999; 2003, 2006), to assess 35 responses to biological interactions (Marshall et al. 2004; Cade et al. 2008), ecosystem change 36 (Choi et al. 2004), as prey to higher trophic levels (Renkawitz et al. 2015), to categorize life 37 history types within a population (Larsen et al. 2017), and to inform population status for 38 management (Blackwell et al. 2000; Brosset et al 2017; Morgan et al. 2018) and conservation 39 (Stevenson and Woods 2006). Depending on the intended purpose (e.g. single species energy 40 content and reproductive potential, or multi-species ecosystem indicators) the desired 41 characteristic of the metric chosen will vary. The concept of overall ‘health’ of an organism is 42 somewhat ambiguous, and considered to be an integration of many factors acting at the sub- 43 organism level that are more clearly defined and quantifiable (e.g. fat content, RNA/DNA, 44 hemoglobin concentration, etc.). The goal of defining the ‘best’ states of condition in individuals 45 and populations, and deviations from this optima, has been a pursuit of fisheries biologists for 46 many years, and approaches can generally be classified as either morpho-physiological (e.g. 2 https://mc06.manuscriptcentral.com/cjfas-pubs Page 3 of 64 Canadian Journal of Fisheries and Aquatic Sciences 47 weight at a given length, hereafter referred to as morphological) or physiological-biochemical 48 (Shulman and Love 1999). To be useful, methods should 1- characterize functional features of 49 organisms or populations, 2- encompass the range of variability in the process examined, 3- be 50 representative of the population, and 4- be easily measured under field conditions (Shulman and 51 Love 1999). While physiological-biochemical methods have generally been more informative, 52 they require more effort and are impractical for field sampling and large sample sizes. Numerous 53 methods have been proposed to relate the physiological health (state of wellbeing, condition) of 54 fishes based on physiological-morphological characteristics, with the premise that heavier or 55 fatter is better (Le Cren 1951; Ricker 1975; Hayes and Shonkwiler 2001). The morphological 56 approach offers ease of collection, but still needs to be validated to some functional feature (e.g. 57 energy content), and often fails to accuratelyDraft reflect nutritional condition of individual fishes. 58 59 The nondestructive nature of morphological indices is appealing, especially if they can be related 60 to variables such as fat or energy content that are much more difficult to measure. Simple metrics 61 such as Fulton’s K relate the weight of an individual to that predicted from the cube of their 62 length; K = W/L3. Though Fulton’s K has been in use for many years (Nash et al. 2006), 63 problems related to the assumption of weight scaling as a cube of length have been demonstrated 64 (Cone 1989). Since the exponent of the weight-length relation deviates from 3 in most species, 65 the calculated Fulton’s K is dependent on size, invalidating comparison of values from samples 66 or individuals of different lengths. The relative condition factor (Kn) does not assume a length 67 exponent, but fits a length-weight relationship to the available data (sample or population). 68 Individual Kn is then calculated as the observed weight/predicted weight based on length (Le 69 Cren 1951); thus, a value of 1 indicates ‘average’ condition. One disadvantage of Kn is that 3 https://mc06.manuscriptcentral.com/cjfas-pubs Canadian Journal of Fisheries and Aquatic Sciences Page 4 of 64 70 given its ‘relative’ nature, when additional data is added a new predictive regression is required 71 which can change prior individual Kn values (e.g. with additional sampling or data, what was 72 considered ‘average’ condition may now be shown to be above or below average). This ‘internal’ 73 (study-specific) aspect of calculating Kn also makes it difficult to compare values across studies. 74 The relative weight index (Wr; Blackwell et al. 2000) addresses this reliance on an internally 75 estimated length-weight relation by using a standard equation for each species (i.e. a ‘global 76 mean’) and allows cross study comparison. Wr has been applied more commonly for freshwater 77 species, where it may be impractical to develop length-weight relations for every pond or lake. 78 More recently, Peig and Green (2009) proposed use of a scaled mass index (SMI), which is 79 based on the central principle of scaling. Compared to other (more traditional) morphometric 80 condition indices, the SMI was shown toDraft be a better predictor of fat and energy reserves in a 81 variety of organisms (small mammals, birds and snakes), and has since been applied to a broader 82 range of animals including amphibians (MacCracken and Stebbings 2012) and fishes (Camizuli 83 et al. 2014; Maceda-Veiga et al. 2014; Morita et al. 2015; Masse et al. 2016). 84 85 In addition to advances in analytic methods for morphological condition indices, new 86 technologies have emerged and been applied to quantify physiological condition, including total 87 body electrical conductivity (TOBEC; Scott et al. 2001), bioelectrical impedance analysis (BIA; 88 Cox and Hartman 2005), and the fatmeter (Crossin and Hinch 2005; Davidson and Marshall 89 2010; Schloesser and Fabrizio 2017). Both TOBEC and BIA operate on the principle that the 90 conductivity of an organism is determined mainly by its lean tissues (Scott et al. 2001). BIA has 91 been applied successfully to estimate whole body fat and energy in fish in several studies (Cox 4 https://mc06.manuscriptcentral.com/cjfas-pubs Page 5 of 64 Canadian Journal of Fisheries and Aquatic Sciences 92 and Hartman 2005; Cox and Heintz 2009; Hafs and Hartman 2011), but less successful in other 93 studies (Pothoven et al. 2008; Garner et al. 2012; Klefoth et al. 2013; Dibble et al. 2017). 94 95 Regardless of condition index chosen, there is a need to relate any index at different stages in a 96 fish’s life to standard physiological variables (e.g. fat or energy density, Davidson and Marshall 97 2010; Schloesser and Fabrizio 2017). For example, because condition indices, whether 98 morphometric or derived from physical [bioelectrical] properties, may reflect different aspects of 99 an individual’s physiologyand may be affected differently by both the reproductive state (on an 100 annual cycle; Robards et al. 1999) and reproductive mode of a given species. This study focuses 101 on three species with different life histories, particularly in terms of reproduction, which is 102 energetically demanding and likely to affectDraft fish condition.

  • Yellowtail Flounder (Limanda Ferruginea) Ageing Manual
    NOT TO BE CITED WITHOUT PRIOR REFERENCE TO THE AUTHOR(S) Northwest Atlantic Fisheries Organization Serial No. N4947 NAFO SCR Doc. 04/5 SCIENTIFIC COUNCIL MEETING – JUNE 2004 Yellowtail Flounder (Limanda ferruginea) Ageing Manual Karen Dwyer Northwest Atlantic Fisheries Centre Abstract This is a technical manual describing the methods and interpretations used for estimating age in yellowtail flounder (Limanda ferruginea). The paper gives a general overview of ageing, and then discusses how yellowtail flounder are presently being aged at the Northwest Atlantic Fisheries Centre (NAFC) in St. John’s, Newfoundland. It also provides information on the types of validation studies that are used to ensure accuracy of ageing, and attempts to troubleshoot any difficult aspects of ageing. The thin-sectioning method used to age this species is discussed, and includes detailed information on how it is carried out. The structure of the whole otolith were discussed, along with the limitations for ageing yellowtail flounder using this structure. This manual contains a glossary and high quality photos and diagrams for use when ageing yellowtail flounder. Introduction Age of marine fish can be determined by counting periodic markings on a variety of ‘hardparts’. Scales, vertebrae, spines and otoliths have been used to determine age in fish. In the case of flatfish otoliths are unique in that they have both symmetrical and asymmetrical sagittal otolith (Hunt, 1992). Age of fish is essential in fisheries management. Hence, accurate age determinations are a vital part of the scientific process of stock assessment and are critical for estimating mortality and growth rates (Chilton and Beamish, 1982; Penttila and Dery, 1988).

Cadrin Yellowtail Flounder Tagging – Final Report 2 ABSTRACT A collaboration with commercial fishermen tagged over 45,000 yellowtail flounder (Limanda ferruginea) with conventional disc tags and data-storage tags in all three New England stock areas with the objectives of estimating movement among stocks areas and mortality as well as providing growth observations. The pattern of release and recapture locations documents frequent movements within stock areas with a less frequent movement among stock areas. Data-storage tags reveal distinct periods of on-bottom and off-bottom behavior associated with movement to different habitats. Simulation of yellowtail flounder life history, stock status, fishery dynamics and the pattern of releases suggest that fishing mortality and movement estimates are confounded and cannot be independently estimated with tagging data alone. Accordingly, survival and recovery rate were estimated for the New England resource as a whole using tag-recovery models. Tag-recovery estimates of survival confirm the general magnitude of mortality estimates from age-based stock assessments, and greater survival of females than males. An integrated catch-at-age model is being developed to include tag recovery data with fishery and survey data to estimate mortality and movement simultaneously.
