“…Larvae depend on unidirectional water flow through their branchial chamber, to provide detritus food and to exchange respiratory gases and metabolic wastes (Hardisty and Potter 1971a). Small larvae (20-60 mm TL) prefer small-grained substrate (silt-sand), medium-sized larvae (60-140 mm TL) prefer medium-grained substrate (gravel-silt-sand), and large larvae (140-200 mm TL) prefer coarsegrained sediments (gravelly-sand and sand) (Almeida and Quintella 2002;Sullivan 2003; (2012) a Lentic habitat larvae are often found in fine-grained sediments, likely because soft sediments allow young larvae with reduced swimming capacity to propel their head and branchial region into the substrate ). In contrast, large larvae colonize a wider range of sediments because their ability to burrow is considerably higher , and because they have had a greater amount of time to colonize multiple habitats (Sullivan et al 2008).…”

“…In contrast, large larvae colonize a wider range of sediments because their ability to burrow is considerably higher , and because they have had a greater amount of time to colonize multiple habitats (Sullivan et al 2008). Because selection of sediment is size-dependent, differences in preference for distinct sediment types within the same age group may have resulted from larval redistribution at the end of each annual growing season, perhaps as a strategy to avoid high density in areas colonized by younger individuals to reduce intraspecific competition for space and food (Almeida and Quintella 2002). Larval distribution is also associated with slow current, although sediment particle size is strongly determined by current velocity, thereby confounding the relative importance of current and substrate particle size in determining larval distribution (Young et al 1990b;Almeida and Quintella 2002).…”

“…For example, larval distribution along a river is strongly associated with spawning areas, with larval density inversely related to distance downstream from spawning areas (Morman et al 1980;Almeida and Quintella 2002;Quintella et al 2003;Derosier et al 2007). Similarly, adults must have access to spawning habitat, so the presence of migration barriers influences larval abundance and distribution (Goodwin et al 2008).…”

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.

“…The larvae or ammocoetes of sea lamprey remain buried in soft substrates and filter-feed on algae, micro-organisms and organic detritus during a period of 4-7 years, prior to adult marine stage (Almeida and Quintella, 2002;Almeida et al, 2008).…”

-Ammocoetes of sea lamprey (Petromyzon marinus Linnaeus, 1758) from an assumedly pristine tidal freshwater habitat were used for determination of metal levels and accumulation patterns with size. The individuals were collected during the winter of 2011 in river Minho (Iberian Peninsula, Southwest of Europe) and the levels of metals (Cd, Cu, Cr, Fe, Pb, Mn and Zn) in the whole body were analysed by atomic absorption spectrometry. Fe was the metal with highest levels (maximum of 1438 ppm), while Cd and Pb were the lowest accumulated elements (overall means of 0.093 ¡ 0.065 ppm and 0.259 ¡ 0.094 ppm, respectively). Larger ammocoetes seemed prone to accumulate Cu, Fe and Mn (P < 0.05). Pb and Zn levels also seemed to increase with ammocoetes size; however, statistical differences were not found between size classes (P > 0.05).

The impact of small physical obstacles on the structure of freshwater fish assemblages

Many studies have assessed the effects of large dams on fishes but few have examined the effects of small obstacles. Fishes were sampled and environmental variables were characterized at 28 sites in two Iberian streams, 14 located immediately downstream, upstream and between five small obstacles at river Muge and 14 at river Erra, considered as the reference stream. Multivariate analysis indicated that habitat variables like current velocity and depth, but not physicochemistry, were mainly responsible for site groups' discrimination in both streams. The reference stream exhibited a longitudinal gradient of current velocity that, however, was not strong enough to cause significant changes in the fish assemblage's composition and structure. By successive and drastically repeating this gradient near each structure, the obstacles stream presented differences in fish fauna between the three site types. Lentic upstream sites presented higher density of limnophilic, omnivorous and exotic species, like gudgeon Gobio lozanoi, which are well adapted to this type of habitat. Downstream and between obstacles sites were characterized by the dominance of rheophilic and invertivorous taxa, especially barbel Luciobarbus bocagei. Richness metrics did not differ among site types, but diversity was higher in sites located between the obstacles away from its direct influence, where the habitat diversity was higher. Contrarily to upstream sites, downstream and between obstacles sites were similar in many of the studied features to the reference stream, implying that this type of structures cause a higher modification in the upstream fish community. This study suggests that the effects of small obstacles on habitat and fishes are similar, in some extent, to those reported for larger dams, providing important considerations for riverine ecosystem conservation efforts.
