The amount of environmental DNA increases with freshwater crayfish density and over time

open access: yesEnvironmental DNA, 2022
Over the last years, the analysis of environmental DNA (eDNA) has become an important approach to investigate species communities. Due to its non‐invasive nature and high sensitivity, this method is excellently suited to monitor the occurrence of ...

EFFECTS OF SOYBEAN MEAL BASED DIET ON GROWTH PERFORMANCE AND HEMOLYMPH BIOCHEMICAL PARAMETERS OF NARROW-CLAWED CRAYFISH (ASTACUS LEPTODACYLUS ESCHSCHOLTZ, 1823) [PDF]

open access: yesCroatian Journal of Fisheries, 2013
Like other crustaceans, narrow-clawed crayfish (Astacus leptodacylus Eschscholtz, 1823) can change its diet to the available food during varied life cycles.

Evaluation of different dietary protein and energy levels on growth performance and body composition of narrow clawed crayfish (Astacus leptodactylus) [PDF]

open access: yes, 2012
Nine practical diets containing increasing percentages of crude protein (CP) and energy (30%, 35%, 40% and 300kcal/100g, 370kcal/100g and 450kcal/100g) were fed to narrow clawed crayfish (mean individual weight=17±2.3 g) during an 8 week feeding trial ...

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, EarlyView.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...
