    AACL BIOFLUX Aquaculture, Aquarium, Conservation & Legislation International Journal of the Bioflux Society The study of frozen Astacus leptodactylus tail fillet quality changes 1Ali Nekuie Fard, 1Masoud Seidgar, 2Dariush Azadikhah 1 National Artemia Research Center, Iranian Fisheries Science Research Institute, Agricultural Research Education and Extension Organization (AREEO), Urmia, Iran; 2 Department of veterinary Medicine, Urmia Branch, Islamic Azad University, Urmia, Iran. Corresponding author: A. Nekuie Fard, [email protected] Abstract. Chemical and microbial quality changes of freshwater crayfish (Astacus leptodactylus) tail fillet were studded during storage at freezing temperature. Samples were packaged and stored in -18 ° C in the freezer after fishing, preparation and peeling in the presence of air. Quality and microbial tests were performed on frozen fillets in time zero and once every month for 6 months with one treatment including three replicates for each test period. The results showed that at the end of six-months storage in freezer, the values (Mean±SE) of thiobarbituric acid (TBARS), peroxide value (PV) and total volatile nitrogenous bases (TVB-N) had reached from 0.05±0.005 to 1.45±0.25 mg, malondialdehyde / kg; 0 to 2.2±0.30 meqO2 kg /fish fat and 11.25±.05 to 26.6±1.40 mg per 100 g of meat, respectively. These values were within the acceptable range for use in spite of exesting significant difference with each other (p<0.05). pH value had no significant changes (p>0.05) until the end of fifth months (6.2±0.25), but this value had a significant increase (6.57±0.55) after the sixth month (p<0.05).

Available evidence from palaeontology, distributional, and genetic studies is examined, as well as records of crayfish in historical documents. The conclusion is that there is sufficient evidence from historical literature to indicate that A. pallipes was in residence in Britain before 1500. This has been accepted by the IUCN.

More than at altitudes above 300 m in subtropical rainforests of the 20 of these are native to Queensland, including the Lamington Plateau, McPherson Range, Cunningham’s smallest species in the world, the Swamp Crayfish Gap, Mistake Mountains and Mt Tamborine. The typical (Tenuibranchiurus glypticus), which reaches little over 25 colour form, restricted to the Lamington Plateau, is bright mm in length.

  • Fresh and Frozen Seafood
    Fresh and Frozen Seafood Selecting and Serving It Safely As with any type of food, it is important to handle seafood safely to reduce the risk of foodborne illness, often called “food poisoning.” Follow these safe handling tips for buying, preparing, and storing fish and shellfish – and you and your family can safely enjoy the fine taste and good nutrition of seafood. Buy Right Fresh Fish and Shrimp Only buy fish that is refrigerated or displayed on a thick bed of fresh ice (preferably in a case or under some type of cover). Because the color of a fish can be affected by several factors including diet, environment, treatment with a color fixative such as carbon monoxide or other packaging processes, color alone is not an indicator of freshness. The following tips can help you when making purchasing decisions: • Fish should smell fresh and mild, not fishy, sour, or ammonia-like. • A fish’s eyes should be clear and shiny. • Whole fish should have firm flesh and red gills with no odor. Fresh fillets should have firm flesh and red blood lines, or red flesh if fresh tuna. The flesh should spring back when pressed. • Fish fillets should display no discoloration, darkening, or drying around the edges. • Shrimp, scallop, and lobster flesh should be clear with a pearl-like color and little or no odor. Fish and shellfish contain • Some refrigerated seafood may have time/temperature indicators high quality protein and on their packaging, which show if the product has been stored at other essential nutrients and the proper temperature.
