“…These results suggest that females grew faster and attained greater FLs than males (a previous study on A. australis did not discriminate between genders; Pollock 1982). This result is consistent with reports on many other Sparidae (Morison et al 1998, Pajuelo & Lorenzo 2000, Pajuelo et al 2006, Alós et al 2010), but gender-related growth patterns in contrast to this are apparent within the family (Pajuelo & Lorenzo 2003, Brouwer & Griffiths 2004, Dulčić et al 2011) and can be confounded due to the prevalence of protandric hermaphroditism displayed by several species, including A. australis (Pollock 1982, Buxton 1993, Pajuelo & Lorenzo 2000, Abou-Seedo et al 2003, Pajuelo et al 2006). Further work is required to determine the levels and effects of hermaphroditism on s exspecific growth rates of A. australis.…”

“…Panella (1980) urged study of zonation in otoliths from different species living in the same or different habitats as a way to identify otolith features that are genetically or physiologically controlled versus those that are environmentally controlled. A quarter century later, only a few authors (Fowler and Doherty 1992;Beckman and Wilson 1995;Brouwer and Griffiths 2004) appear to have attempted such comparisons, although the latter two efforts involved qualitative reviews of prior studies. Beckman and Wilson (1995) also suggested studying multiple populations of the same species across a broad geographic range to address the conflicting results reported in their review article.…”

Validation of scales and otoliths for estimating age of redband trout in high desert streams of Idaho

2010

Studies validating aging structures for rainbow trout are sparse and none have been conducted for redband trout, a common western U.S. sub-species. Oxytetracycline mark-recapture methods (MR), marginal incremental analysis (MIA), and comparisons across multiple populations were used to evaluate the utility of two structures for aging redband trout in high desert streams. We assessed periodicity of annulus formation on scale and otolith samples from all age classes of trout residing in two streams, identified the location of the first annulus on otoliths, and compared age estimates and between-reader coefficient of variation on nine additional streams. The use of MIA successfully validated opaque zone periodicity for fish transitioning from age-0 to age-1, and from age 1 to age 2 in two streams. For fish at liberty 13 and 28 months in the same two streams, MR-derived age estimates from whole and sectioned otoliths were 94-100% accurate for fish from 2-9 years old. Scales were only 77% and 38% accurate for fish at liberty 13 and 28 months, respectively. Between-reader coefficient of variation (CV) for scales was high (11.5%), while CV for sectioned otoliths using whole otoliths as corroboratory structures averaged 2.3%. Scales were thus, an unacceptable aging structure for desert redband trout. Given the confusion in the literature, we suggest that more rigorous research should be conducted to define and explain otolith zone formation.

“…While past age estimates relied on reading whole otoliths, the present study presents the first use of sectioned otoliths for age determination on whole otoliths tend to underestimate age compared to those using sectioned otoliths, this discrepancy is species-dependent and typically occurs when trying to age longer-lived species that have accumulated very thick otoliths. Thicker otoliths are thought to make reading thinner increments at older ages more difficult (Brouwer & Griffiths, 2004;Buxton & Clarke, 1991;Francis, Paul, & Mulligan,1992;Sequeira et al, 2013); however, the shorter life span and subsequently thinner otoliths of the Giant Kelpfish enabled accurate age estimation for this species using an otolith-sectioning methodology. …”

Age and growth of the Giant Kelpfish,Heterostichus rostratusGirard 1854,in Southern California, USA

Summary In order to update existing life history parameters, age and growth patterns were determined for Giant Kelpfish, Heterostichus rostratus sampled from nearshore kelp forest and estuary habitats in southern California (USA) from April 2012 through June 2015. Fish were collected by pole spear, beach seine, beam trawl, purse seine, and square enclosure. Using age‐at‐length data derived from otolith readings, Giant Kelpfish were found to have a relatively short life span with the largest examined fish reaching a maximum total length of 413 mm at an age of 5 years. Von Bertalanffy growth parameters estimated for this species were: L∞ = 45.1 cm, k = 0.25, t0 = −0.66. Standard length (SL, cm)‐total length (TL, cm) and total length (TL, cm)‐weight (W, g) relationships were described by the equations: SL = 0.90 TL – 1 and W = 2.21 × 10−3 TL3.39, respectively. Wild juvenile Giant Kelpfish collected for this study had a higher growth rate than laboratory‐reared fish from a previous study.
