“…Larvae from the River Mondego, Portugal, had shorter larval stage duration (Quintella et al 2003) than in more northerly river basins, such as anadromous populations in Canada (range = 6-8 years; Beamish and Potter 1975) and Great Britain (average = 5 years; Hardisty 1969a, b), likely because higher productivity associated with warmer water enhances feeding efficiency and growth (Morman 1987). As expected for a poikilothermic organism, growth of sea lamprey larvae is correlated with water temperature (Potts et al 2015), and varies among geographic regions with different climatic conditions, with faster growth in more favorable climates (Potter 1980;Dawson et al 2015).…”

“…After hatching, blind, poor-swimming larvae are carried downstream from nests to depositional areas of sand, silt, and detritus, where they burrow into soft sediments to feed on suspended organic matter (Sutton and Bowen 1994;Dawson et al 2015). Dispersal from nests is highly variable and is influenced by larval density and water temperature (Derosier et al 2007).…”

“…Last, metamorphosing lampreys are often found in the same sites where larvae of all sizes are found (Potter 1980;Quintella et al 2003). During the initial stage of metamorphosis, transforming juveniles are relatively more sedentary than larvae (Quintella et al 2005), whereas later on, juveniles burrow less, so are found hiding between pebbles, and under aquatic vegetation, rocks, and other structures (Dawson et al 2015).…”

“…In a Lake Ontario tributary, the first year class to infest a stream following lampricide treatment grew faster than subsequent year classes (Weise and Pajos 1998), which suggests growth was density dependent (Dawson et al 2015). In the River Mondego, Portugal, larval sea lampreys averaged 59 mm in TL (range = 53-74 mm) at age 0?…”

“…Age estimation of sea lamprey larvae, particularly in controlled populations, initially relied on analysis of length-frequency data (Table 3) but can be supplemented by knowing the number of years since known recruitment (Weise and Pajos 1998;Hansen et al 2003;Dawson et al 2015). However, growth rates vary greatly within and among cohorts within stream populations, so age cannot be accurately assigned from length-frequency histograms (Dawson et al 2009), especially for older age classes (Hardisty and Potter 1971a;Hardisty 1979).…”

The sea lamprey Petromyzon marinus (Linnaeus) is both an invasive non-native species in the Laurentian Great Lakes of North America and an imperiled species in much of its native range in North America and Europe. To compare and contrast how understanding of population ecology is useful for control programs in the Great Lakes and restoration programs in Europe, we review current understanding of the population ecology of the sea lamprey in its native and introduced range. Some attributes of sea lamprey population ecology are particularly useful for both control programs in the Great Lakes and restoration programs in the native range. First, traps within fish ladders are beneficial for removing sea lampreys in Great Lakes streams and passing sea lampreys in the native range. Second, attractants and repellants are suitable for luring sea lampreys into traps for control in the Great Lakes and guiding sea lamprey passage for conservation in the native range. Third, assessment methods used for targeting sea lamprey control in the Great Lakes are useful for targeting habitat protection in the native range. Last, assessment methods used to quantify numbers of all life stages of sea lampreys Fish Biol Fisheries (2016) 26:509-535 DOI 10.1007 would be appropriate for measuring success of control in the Great Lakes and success of conservation in the native range.

Knowledge of the biology, distribution, and abundance of lampreys (Petromyzontiformes) is critical to inform conservation actions for native species and to inform control measures for the invasive Sea Lamprey Petromyzon marinus of the Laurentian Great Lakes. Lampreys have complex life cycles that include a freshwater larval stage in which they burrow into substrates consisting of fine sediment and organic matter. The larval stage is frequently targeted in research and monitoring; given this interest, a review of survey designs and methods is needed. Our review identified 12 different sampling methods for larval lampreys and focused on one common method-backpack electrofishing in wadeable habitats. Our review also identified eight research and monitoring questions that have been addressed for larval lampreys in field studies, including distribution, species identification, life stage occurrence, abundance, length frequency, habitat use, residence and movement phenology, and species status. Each question provides unique information and poses distinct challenges to data acquisition and interpretation. The objectives guide decisions about study design and scope of inference. The scope of inference is determined by the size, spatial distribution,

ObjectiveThe anadromous Pacific Lamprey Entosphenus tridentatus is an ecologically and culturally important fish that has experienced declines in abundance and distribution throughout large portions of its range. However, the lack of fundamental biological information, such as age and growth, impedes management and conservation efforts.MethodsWe used known‐age hatchery and wild Pacific Lamprey to evaluate the potential of statoliths (apatite concretions found within the auditory capsules) to provide estimates of individual size and age throughout ontogeny. Statolith size and growth were assessed with comparisons of morphometrics (area, perimeter, length, and width) in relation to fish length. Traditional band‐reading methods and random forest (RF) analysis were evaluated for their utility in estimating age.ResultWe observed a strong, positive relationship between statolith size and fish length for larvae that were hatchery reared. However, there were no positive relationships between statolith size and fish length for any of the postmetamorphic life stages, which indicates that statolith growth slows dramatically or ceases after metamorphosis. Band‐reading methods of statoliths from known‐age lamprey (1‐ and 2‐ to 9‐year‐olds) resulted in accurate age estimates for 28% of the fish, and 57% of mean age estimates fell within 1 year of the true age. While we found that the statolith was not very useful for traditional age estimation techniques, its inclusion in morphometric‐based age classifications was promising. A RF model based on body length, collection river, and statolith area accurately assigned 76% of the larval and freshwater juveniles to their known age. Additionally, an RF model using only body length and river of origin correctly classified 70% of the known‐age samples.ConclusionMultivariate approaches, including those that include lethal and nonlethal predictor variables, provide potential approaches to estimate age in larval and early juvenile Pacific Lamprey.
