Abstract To explore the damage mechanisms of freeze-thaw cycles on cooked crayfish in frozen storage, changes physicochemical properties and structure during were investigated. The changed significantly after five cycles. moisture content, water holding capacity, pH, textural decreased, while total color difference, drip loss, protein lipid oxidation increased ( P < 0.05). LF-NMR MRI verifie...

Freshwater crayfish, which are cultivated in aquaculture, economically important for food and ornamental purposes. However, relatively few studies have focused on potentially pathogenic viruses crayfish compared to penaeid shrimp. Commodity red claw (Cherax quadricarinatus; 400 10 batches) swamp (Procambarus clarkii; 40 2 imported into South Korea from Indonesia China were screened by PCR detec...

The effects of dietary supplementation two different macroalgae Ulva lactuca and Jania rubens on the growth performance, survival feed conversion ratio juvenile red swamp crayfish (Procambarus clarkii) were investigated. Red with an average total length 56.2±6.67 mm weight 3.77±0.2 g placed at tanks (10 each tank) offered diets 8 weeks. Different levels added to commercial sea bass feed, no sea...

The present study was conducted to evaluate the effect of 20 d starvation on growth, survival, histomorphology and ultrastructure changes in the digestive system of juvenile red swamp crayfish (Procambarus clarkii). Juveniles were divided into two groups: a food-deprived group and a control group at 9 day after hatch (DAH). Individuals were sampled at 14, 20, 29 DAH. During the 20 d fasting per...
