Growth of adult chokka squid Loligo reynaudii d’Orbigny was modelled using mantle length and age data derived from samples collected over two years (2003 and 2004) from a single, large cohort of mature and spawning squid. A total of 588 statoliths

Are there long-term temporal trends of size composition and the length– weight relationship? Results for chokka squid Loligo reynaudii during the peak spawning season off the south coast of South Africa

Autor: J Githaiga-Mwicigi, Dawit Yemane, Lipiński, MA Mmethi, W. H. H. Sauer

Publikováno v: African Journal of Marine Science. 43:227-238

Temporal trends in the size composition (length frequency) and length–weight (L–W) relationship of chokka squid Loligo reynaudii on the south coast of South Africa were assessed over periods spanning 22 years: length frequencies from 1996 to 2017

Sperm competition risk affects ejaculate strategy in terms of sperm number but not sperm size in squid

Autor: Warwick H. H. Sauer, Noritaka Hirohashi, Noriyosi Sato, Paul W. Shaw, Yoko Iwata, Yoshiro Watanabe

Publikováno v: Journal of evolutionary biologyREFERENCES. 34(9)

In polygamous species, the mode of sperm storage in females influences evolution of sperm quantitative and qualitative traits because it provides the arena for sperm competition, cryptic female choice and fertilization processes. In this study, we co

Concentrations and relative compositions of metallic elements differ between predatory squid and filter-feeding sardine from the Indian and South Atlantic oceans

Autor: Carl D. van der Lingen, Henrik Kylin, Ryan C. Uren, Hindrik Bouwman

Although metallic elements occur naturally, they can occur or accumulate in organisms at levels toxic to the organism and/or their consumers. Concentrations of twenty-nine metallic elements in muscle tissue from sardine Sardinops sagax and chokka squ

Halogenated natural products and anthropogenic persistent organic pollutants in chokka squid (Loligo reynaudii) from three sites along the South Atlantic and Indian Ocean coasts of South Africa

Autor: Hindrik Bouwman, Ryan C. Uren, Carl D. van der Lingen, Qiong Wu, Walter Vetter

Publikováno v: Environmental pollution (Barking, Essex : 1987). 255(Pt 2)

Chokka squid (Loligo reynaudii) from three sites along the South African coast were analyzed for halogenated natural products (HNPs) and anthropogenic persistent organic pollutants (POPs). HNPs were generally more than one order of magnitude more abu

Biophysical models of larval dispersal in the Benguela Current ecosystem

Autor: Christophe Lett, CD van der Lingen, Coleen L. Moloney, B. R. Loveday

Publikováno v: African Journal of Marine Science. 37:457-465

We synthesise and update results from the suite of biophysical, larval-dispersal models developed in the Benguela Current ecosystem. Biophysical models of larval dispersal use outputs of physical hydrodynamic models as inputs to individual-based mode
