Life Cycle and Biology of Portunid Crabs [PDF]

open access: yes, 2015
In crustaceans, as growth progresses, certain dimensions of the animal’s body may grow much more than others, resulting in the phenomenon known as relative growth (Hartnoll, 1974). Studies of relative growth are often used to determine changes in the

Risk assessment of complex organoarsenic species in food

open access: yesEFSA Journal, Volume 22, Issue 12, December 2024.
Abstract The European Commission asked EFSA for a risk assessment on complex organoarsenic species in food. They are typically found in marine foods and comprise mainly arsenobetaine (AsB), arsenosugars and arsenolipids. For AsB, no reference point (RP) could be derived because of insufficient toxicity data.

The highly rearranged mitochondrial genomes of the crabs Maja crispata and Maja squinado (Majidae) and gene order evolution in Brachyura [PDF]

open access: yes, 2017
We sequenced the mitochondrial genomes of the spider crabs Maja crispata and Maja squinado (Majidae, Brachyura). Both genomes contain the whole set of 37 genes characteristic of Bilaterian genomes, encoded on both \u3b1- and \u3b2-strands.

Bottom Trawling and Multi‐Marker eDNA Metabarcoding Surveys Reveal Highly Diverse Vertebrate and Crustacean Communities: A Case Study in an Urbanized Subtropical Estuary

open access: yesEnvironmental DNA, Volume 6, Issue 6, November–December 2024.
We demonstrated the effectiveness of eDNA metabarcoding as a valuable addition to bottom trawling for monitoring the species composition and spatial distribution of fish and crustacean communities in urban estuaries. We also showed that a multiplexed‐marker approach enhances species detection, especially in some taxa, for example, cartilaginous fish ...

Effect of Enriched Artemia sp. by EPA (Eicosapentaenoic Acid; C20:5n-3) and DHA (Docosahexaenoic Acid; C22:6n-3) on Survival Rate of Swimming Crab Portunus pelagicus

open access: yesJurnal Akuakultur Indonesia, 2007
Nutrient content of natural food is one of the main factors for determining the successful of marine fish fry production.  EPA (Eicosapentaenoic Acid) and DHA (Docosahexaenoic Acid) are two essential fatty acids for marine fish larvae.

Late Holocene hunting economies in coastal southeastern Australia: Insights from the archaeological fauna of Curracurrang 1 Rockshelter, Royal National Park

open access: yesArchaeology in Oceania, Volume 59, Issue 2, Page 350-381, July 2024.
ABSTRACT Curracurrang 1 (1CU5) is a rockshelter site located in the Royal National Park (RNP) on the coast south of Sydney. Excavated from 1962 to 1966, the site's rich Holocene cultural deposit has become important for understanding regional Late Holocene developments in Australian lithic and shell technologies.
