Updated 2021 assessments of Jasus Tristani rock lobster at Gough Island

open access: yes, 2021
This paper provides an updated assessment of the Jasus Tristani rock lobster resource at Gough Island. This assessment includes updated data from the commercial fishery and biomass surveys for the 2018 and 2019 seasons. Data from the 2020 season are not included as they are not yet fully available. This assessment was last updated in 2018.

Revised 2021 assessment of Jasus tristani rock lobster at Gough island

open access: yes, 2021
This paper provides a revised updated assessment of the Jasus tristani rock lobster resource at Gough island. This revision constrains the sigma values of the commercial and biomass survey indices to be ≥0.15. It also now takes updated standardised CPUE and discard % data from the commercial fishery for the 2020 season as well as the final catch figure

The efficacy of electrical stunning of New Zealand rock lobster (Jasus edwardsii) and freshwater crayfish (Paranephrops zealandicus) using the Crustastun™

open access: yesAnimal Welfare, 2023
Large numbers of decapod crustacea are farmed and harvested globally for human consumption. Growing evidence for the capacity of these animals to feel pain, and therefore to suffer, has led to increased concern for their welfare, including at slaughter ...

Environmental determinants of suitable habitat and the prediction of a southern shift in the future distribution of spiny lobsters, genus Jasus

open access: yesbioRxiv, 2023
Climate change is altering environmental conditions which is affecting species habitats globally. As a result, many species are shifting their habitat ranges poleward to ensure that they remain within their optimal thermal range.

The impact of seismic survey exposure on the righting reflex and moult cycle of Southern Rock Lobster (Jasus edwardsii) puerulus larvae and juveniles.

open access: yesEnvironmental Pollution, 2022
Anthropogenic aquatic noise is recognised as an environmental pollutant with the potential to negatively affect marine organisms. Seismic surveys, used to explore subseafloor oil reserves, are a common source of aquatic noise that have garnered attention

Disentangling genetic from environmental effects on phenotypic variability of southern rock lobster (Jasus edwardsii) postlarvae

open access: yesEcology and Evolution, 2022
Environmental conditions experienced during the larval dispersal of marine organisms can determine the size‐at‐settlement of recruits. It is, therefore, not uncommon that larvae undergoing different dispersal histories would exhibit phenotypic ...

Cardiac mitochondrial energetics of the Australasian red spiny lobster, Jasus edwardsii, when exposed to isoeugenol within the commercial anaesthetic AQUI-S.

open access: yesJournal of Experimental Biology, 2022
The anaesthetic isoeugenol has been used as metabolic suppressant for commercial transport of live lobsters in order to decrease energy expenditure aand improve survival. Given the central role of mitochondria in metabolism and structural similarities of

Distribution of Jasus spp. (Decapoda : Palinuridae) phyllosomas in southern waters: implications for larval recruitment [PDF]

open access: yes, 2000
We sampled the distribution of mid- and late-stage (= advanced) Jasus group 'lalandii' rock lobster phyllosomas at 28 approximately equidistant stations across similar to 16 000 km of ocean between the west coast of Africa and the west coast of New ...
