Amino Acid Profiles In The Midgut, Ovary, Developing Eggs And Zoes Of The Mud Crab, Scylla Serrata

Abstract

As from January 2010 The Israeli Journal of Aquaculture-Bamidgeh (IJA) will be published exclusively as an on-line Open Access (OA) quarterly accessible by all AquacultureHub (http://www.aquaculturehub.org) members and registered individuals and institutions. Please visit our website (http://siamb.org.il) for free registration form, further information and instructions. This transformation from a subscription printed version to an on-line OA journal, aims at supporting the concept that scientific peer-reviewed publications should be made available to all, including those with limited resources. The OA IJA does not enforce author or subscription fees and will endeavor to obtain alternative sources of income to support this policy for as long as possible.

Effects of two natural diets on the biochemical compositions of post‐mating female mud crab ( Scylla paramamosain )

“…In S . serrata , arginine, histidine, lysine, methionine, tyrosine and threonine decreased with egg embryogenesis, suggesting that these are the major free amino acids utilized as the egg develops (Peñaflorida, 2004). Due to the higher content of amino acids (i.e., alanine, methionine, leucine and tyrosine) in the ovary of crabs fed with P .…”

“…In S. paramamosain, requirement is needed at different maturation stages (Wu et al, 2020). In S. serrata, arginine, histidine, lysine, methionine, tyrosine and threonine decreased with egg embryogenesis, suggesting that these are the major free amino acids utilized as the egg develops (Peñaflorida, 2004). Due to the higher content of amino acids (i.e., alanine, methionine, leucine and tyrosine) in the ovary of crabs fed with P. rubromuscula, it can be concluded that this diet could be used as a suitable candidate to promote the ovarian development.…”

“…In addition to its role in protein synthesis, it plays critical roles in nutrition, metabolism and signalling (Brodsky et al, 2017). In crustaceans, amino acids form a major component of the egg, which provides an essential food source for embryonic development (Peñaflorida, 2004). In marine crab C. japonica, the ovarian TAA and EAA significantly increased from immature to mature stages (Xu et al, 2014).…”

Insight of vitellogenesis patterns: A comparative analysis of the differences between the primary and secondary vitellogenesis period in the ovary, hepatopancreas, and muscle of mud crab, scylla paramamosain

“…In aquatic crustaceans, lipids, which are critical energy nutrients, mainly include fatty acids, phospholipids, and sterols and are indispensable for many reproduction-related processes, including ovarian development, egg formation, spawning, embryogenesis, and early larval development ( Harrison, 1990 ; Xu et al, 1994 ). Amino acids serve as an essential nutrient source for ovarian maturation, embryonic development, spawning, and hatching ( Peñaflorida, 2004 ). Previous studies have revealed the biochemical compositions of the edible parts of S. serrata ( Peñaflorida, 2004 ; Romano et al, 2014 ), S. olivacea ( Taufik et al, 2020 ), and S. paramamosain ( Jiang et al, 2014 ; Tantikitti et al, 2015 ).…”

Wu et al (2020) clarified the dynamics of the biochemical composition, including lipids and amino acids, in the ovary, hepatopancreas, and muscle of S. paramamosain during the ovarian maturation period.…”
