“…This is unfortunate since aerobic scope appears to change markedly during early ontogeny. In the study by Geist et al (), the scope for spontaneous activity was much greater in small larvae (from 2 to 8) compared with juveniles (generally 1·5–3·0). Ruzicka & Gallager () calculated what they termed ‘routine factorial scopes’ equal to RMR:BMR and concluded that the value of this ratio was 3·8 to 5 times higher in larvae swimming in a large (250 l) tank compared with larvae confined to a small respirometer.…”

“…Optodes allowed relatively short durations of measurement cycles for RMR ( c . 10 min; Geist et al , ) compared with all the other methods. Manometric and Winkler methods employed longer measuring times (1·5–10·0 h, and >10·0 h, respectively) than either polarographic or paramagnetic (Oxymax) (0·5–5·0 h, and 0·5 h, respectively) methods.…”

“…Thus, larvae exhibit saltatory swimming behaviour with bouts of activity that exist over short time scales (often only s) separated by periods of inactivity. When many repeated measurements of O 2 consumption rate were made on the larvae of Cape horse mackerel Trachurus capensis Castelnau 1861, Geist et al () calculated the mean of the 0·95, 0·50 and 0·05 quantiles and defined these as AMR, RMR and SMR, respectively. This allowed those authors to estimate what they termed the ‘factorial aerobic scope for spontaneous activity’.…”

Metabolic costs can be extremely high in marine fish larvae and gaining reliable estimates of the effects of intrinsic and extrinsic factors on those costs is important to understand environmental constraints on early growth and survival. This review provides an historical perspective of measurements of larval marine fish respiration (O 2 consumption) including the methods (Winkler, manometric, polarographic, paramagnetic and optodes) and systems (closed system to intermittent-flow) used. This study compares and systematically reviews the results (metabolic rates, ontogenetic changes and taxonomic differences) obtained from 59 studies examining 53 species from 30 families. Standard (anaesthetized or darkness), routine and active respiration rates were reported in 14, 94 and 8% of the studies and much more work has been performed on larvae of temperate (88%) compared with tropical (9%) and polar (3%) species. More than 35% of the studies have been published since 2000 owing to both advances in oxygen sensors and the growing emphasis on understanding physiological effects of environmental change. Common protocols are needed to facilitate cross-taxa comparisons such as the effect of temperature (Q 10 : 1⋅47-3⋅47), body mass (slope of allometric changes in O 2 consumption rate from 0⋅5 to 1⋅3) and activity level on metabolic costs as measured via respiration rate. A set of recommendations is provided that will make it easier for researchers to design measurement systems, to judge the reliability of measurements and to make inter-comparisons among studies and species.

“…Worldwide, environmental conditions play an important role in the growth of Trachurus species (Geist et al 2013, Sassa et al 2014). In the FishBase (Froese and Pauly 2015), the growth parameters of other Trachurus species were associated with low water temperature (average = 14.4 °C, n = 50).…”

ABSTRACT. The rough scad, Trachurus lathami Nichols, 1920, is a small pelagic species distributed along the West Atlantic coast.It is most abundant in the Southern Brazil (28°30'-34°S) and in the Southeastern Brazilian Bight (SEBB, 22°-28°30'S). The rough scad is fished by purse seines, which main target is the Brazilian sardine, Sardinella brasiliensis (Steindachner, 1879). Age and growth are vital to understand the life cycle of a species, to fishery management and ecosystem modeling. This study aimed to assess the age and growth of T. lathami, to identify its age structure in the SEBB, and to evaluate what causes the wide differences among 1975 and 2008-2010, indicating that the otolith development, the growth pattern and the age structure remained stable. T. lathami is the smallest species of Trachurus and it has the highest growth rates among them. This is probably related to the different temperatures where larvae/juvenile and adult grow, to the absence of a strong fishing pressure and to decadal population variability.
