A histological study on the development of the digestive system of Pseudosciaena crocea larvae and juveniles
The ontogenetic development of the digestive tract and accessory organs in large yellow croaker (Pseudoscianea crocea) was described using light microscopy from hatching up to the juvenile stage (40 days post hatch, dph). At 3 dph (4.1 0.1 mm total length, LT), coinciding with the buccopharynx opening, larvae started to feed exogenously, and the digestive tract consisted of a welldeveloped bucc...
متن کاملEffects of Different Salinities on Juvenile Growth of Gammarus aequicauda (Malacostraca: Amphipoda)
Gammarus aequicauda is a euryhaline amphipod that is a common inhabitant of brackish environments of the Mediterranean Sea. In the Ebro delta, the population density of G. aequicauda is highly variable throughout the year. The main objective of this study is to investigate the effect of salinity on the growth of G. aequicauda juveniles. G. aequicauda embryos and juveniles can survive and grow i...
متن کاملIsolation and Characterization of Collagen and Antioxidant Collagen Peptides from Scales of Croceine Croaker (Pseudosciaena crocea)
Acid soluble collagen (ASC) from scales of croceine croaker (ASC-C) was successfully isolated with the yield of 0.37% ± 0.08% (dry weight basis), and characterized as type I collagen on the basis of amino acid analysis and electrophoretic pattern. The antioxidant hydrolysate of ASC-C (ACH) was prepared through a two-stage in vitro digestion (4-h trypsin followed by 4-h pepsin), and three antiox...
متن کاملPurification and Characterization of Antioxidant Peptides of Pseudosciaena crocea Protein Hydrolysates.
Two peptides with antioxidant activity were isolated from Pseudosciaena crocea proteins. Pseudosciaena crocea muscle was hydrolyzed with neutral protease to obtain Pseudosciaena crocea protein hydrolysates (PCPH). After ultrafiltration through molecular weight cut-off membranes of 10, 5 and 3 kDa and assessment of free radical scavenging ability, the fraction (PCPH-IV) with the highest antioxid...
