Some physico-chemical properties of Astacus astacus hemocyanin

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1981
1. 1. Some physico-chemical properties of freshwater crayfish Astacus astacus were established i.e. amino acid composition, terminal amino acids, isoelectric point and a number of subunits with their molecular weights. 2. 2. Glutamic acid and asparatic acid compose 25% of all amino acids. 3. 3. N-terminal amino acid is blocked. 4.

Aquaculture of juvenile Astacus astacus in a greenhouse

2013
Our recent research revealed more than 36% decline in the number of Croatian populations of noble crayfish when compared to historical data. Such alarming negative trend requires immediate conservation activities where restocking and stocking of the available freshwater ecosystems with noble crayfish from remaining populations is an important part.

Predation on larvae of the noble crayfish, Astacus astacus L.

Aquaculture, 1990
Abstract The predation by dragonfly larvae ( Aeschna grandis ) and adult female crayfish on second-stage young of the noble crayfish, Astacus astacus , was studied in aquarium experiments. Combinations of crayfish young with and without adult female crayfish, with and without shelter were made in 4×4 set-ups with dragonfly larvae and 4×2 without ...

Astacus astacus.

2010
The Noble Crayfish (Astacus astacus) is a widespread species, it has undergone significant declines in population numbers due to non-indigenous species, crayfish plague, habitat loss and over-harvesting. Estimates of rate of decline in Sweden, Finland and Norway are as high as 78%, ~20% and 61% respectively over a 3 generation length period.

Application of microsatellite analysis on Astacus astacus and Astacus leptodactylus populations from Croatia – preliminary results

2015
Recently, microsatellite markers have been successfully applied to reveal genetic patterns in populations of different European crayfish species. In this preliminary research, we used four microsatellites primarily aiming to check their possible usefulness in detecting hybrids between noble and narrow-clawed crayfish.

High-throughput discrimination of bacteria isolated from Astacus astacus and Astacus leptodactylus

2013
Bacterial diseases and pathogens of crayfish are common, widespread, and occasionally causing serious mortalities. In order to take rapid measures for correct treatment of crayfish diseases, the turnover time and accuracy in bacterial identification is an issue. Bacteria isolated from tissues of apparently healthy Astacus astacus and A.

Morphometric Characteristics of Noble Crayfish (Astacus astacus) in Croatia

2006
Noble crayfish (Astacus astacus (Linnaeus, 1758)) is one of four native European crayfish species inhabiting Croatian freshwater habitats and it is protected by the Croatian law. It is naturally distributed in continental part of Croatia in the Drava-Danube and Sava River basins, forming both river and lake populations and it also occurs in the ...

Temperature acclimation of walking in the crayfish Astacus astacus L.

Comparative Biochemistry and Physiology Part A: Physiology, 1983
Abstract 1. 1. Crayfish (Astacus astacus L.) were acclimated for 3–12 days at 5°C and 20°C. The effect of temperature on the rate of spontaneous walking in intact animals was measured. 2. 2. The spontaneous walking showed a bimodal rate-temperature curve with peaks at 0.5° and 20°C in the cold-acciimated and at 5° and 26°C in the warm ...
