“…Mollusc species such as the Eastern oyster Crassostrea virginica (Buchanan et al 2001), freshwater pond snail Lymnaea stagnalis (Abe et al 2009), and the boring clam Pholas dactylus (Shimomura 2009) have been reported to exhibit autofluorescence. Although autofluorescence of haliotid shells has been reported (Proudfoot et al 2008), there have been no reports detailing autofluorescence encountered in haliotid tissues, with only one article mentioning autofluorescence of Haliotis asinina ova during investigation of the egg coat of this species (Suphamungmee et al 2010). The only reported study using a fluorescent reporter protein (enhanced green fluorescent protein (EGFP)) in a haliotid species was during the transfection of ova, embryos, and sperm in Haliotis discus hannai by Wang et al (2004), with no mention made of autofluorescence.…”

Fluorescent molecules have revolutionized the field of molecular biology and biotechnology, and could be of benefit to research conducted on economically important haliotid species (abalone) for applications such as protein analysis, cell metabolism studies, fluorescence resonance energy transfer, cell imaging, and reporter genes for gene transfer. Many marine organisms exhibit autofluorescence; therefore, this raises the question whether autofluorescence also occurs in abalone and whether it could hinder fluorescence studies. We examined ova, sperm, larvae, juveniles, and hemocyte cell cultures of the southern African abalone (Haliotis midae Linnaeus, 1758) and established that ova, larvae, and juveniles exhibited autofluorescence at most wavelengths tested, especially in the mid-wavelength range of the visible spectrum. Autofluorescence was particularly prominent at the same wavelengths as that of green fluorescent proteins. Therefore, we caution studies using fluorescent molecules with emissions in the mid-wavelength range and suggest the use of molecules with emissions at the extremes of the light spectra.

“…The time and financial constraints of obtaining growth parameters directly through tag-recapture studies limit the number of samples collected (Proudfoot et al 2008). Owing to the large number of samples with maturity data, the advantage of obtaining growth parameters indirectly through maturity data was explored.…”

A legal minimum length (LML) aims to protect spawning biomass but the implementation uncertainty associated with broad-scale LMLs is rarely assessed. LML estimates can require both growth and maturity data; however, growth data is often lacking and this can limit the estimation of an appropriate LML. To overcome the shortfall in growth data, a method is introduced for inferring growth parameters from size at maturity data. In this way, fine-scale theoretical LML estimates were obtained in the absence of empirical growth data. A total of 252 populations of blacklip abalone (Haliotis rubra) were examined and, of those, 46 were identified as having a relatively lower level of protection because they matured at larger sizes. These 46 populations are potentially at greater risk of overfishing as a consequence of implementation uncertainty. Furthermore, the majority of the 46 populations were in an economically valuable region of the fishery. With extensive data on size at maturity, the relative risk to recruitment potential can be assessed and equalised across a fishery.

“…Juvenile red abalone were sourced from The Cultured Abalone Farm (Goleta, CA, USA). Two distinct size classes of juvenile abalone were utilized in this study, as smaller individuals exhibit proportionally greater growth rates (Tarbath et al, 2000;Proudfoot et al, 2008). The large abalone size class (43.4 ± 3.7 mm) were surplus from an earlier pilot study, and all 63 individuals had been maintained for over one year under ambient seawater conditions.…”

“…Digestive physiology and dietary requirements of juvenile abalone shift with age and between species (Bansemer et al, 2016;Frederick et al, 2022b), offering a potential explanation for the varied results observed among our abalone size classes. This variability may be attributed to the sigmoidal growth in red abalone, as larger abalone may grow at proportionally slower rates (Tarbath et al, 2000;Proudfoot et al, 2008). The consumption of dulse within each abalone size class was similar across temperature regimes indicating that the palatability of different dulse cultures did not influence subsequent growth results.…”

Changes in climate conditions can have cascading repercussions for organismal performance and survival, altering the productivity of aquatic systems. While numerous studies have examined the direct effects of temperature on species fitness, fewer studies have analyzed how individual impacts may translate to downstream primary consumers. Temperature-induced changes in the nutritional quality of seaweed may cause critical shifts in energy and nutrient availability for these consumers. A multifaceted experiment was conducted to assess the indirect impacts of California’s coastal climate conditions on abalone growth. This experiment fed juvenile red abalone (Haliotis rufescens) of two different size classes in ambient water conditions with the seaweed dulse (Devaleraea mollis), conditioned at 13°C, 15°C, and 17°C for 92 days. Nutritional analyses revealed significantly higher protein and nitrogen content in the 17°C dulse culture than in the 15°C and 13°C cultures, and no significant differences in carbohydrates. Furthermore, analyses on body weight ratio and condition factor indicate that juvenile red abalone of smaller size display significantly better growth and condition when fed dulse cultured at higher temperatures. Differences between size classes suggest that temperature changes, and subsequent shifts in the nutritional composition of dulse, may have greater impacts on smaller, younger red abalone.
