A Comparative Analysis of the Growth Performance, Morphological Indicators, and Transcriptome Between Two Coastal Regions of China in the Mud Crab (Scylla paramamosain)

Aquaculture Research, Journal Year: 2025, Volume and Issue: 2025(1)

Published: Jan. 1, 2025

The mud crab ( Scylla paramamosain ), a commercially important species in China, is widely distributed along the southeastern coast. This study compares growth performance, morphological traits, and transcriptomic profiles of two geographically distinct populations from Sanmen County, Zhejiang (SMC) Zhangpu Fujian (ZPC). Juvenile crabs collected both regions were reared ponds under identical conditions for 7 months. Key results showed that SMC population exhibited significantly higher daily weight gain, specific rate (SGR), propodus‐to‐cheliped length ratio compared to ZPC p < 0.01 sexes). Transcriptomic analysis revealed 44 consistently upregulated differentially expressed genes (DEGs) individuals. Among these, Otop (Otopetrin 1), Smyd (SET MYND domain containing), AM1159 Cancer pagurus Cuticle protein AM1159), PPAF1 (PPAR gamma coactivator 1 α NARG2 (NMDA receptor regulated 2) functionally linked molting regulation crustaceans. Notably, mTOR pathway‐associated QDPR [Quinoid dihydropteridine reductase] NLRC 3 [NLR family CARD containing 3]) several energy/nutrient metabolism also SMC. Enrichment identified four active KEGG pathways SMC: “Melanogenesis,” “Riboflavin metabolism,” “Choline “Ribosome biogenesis.” These findings suggest superior performance may stem enhanced efficiency nutrient allocation mechanisms.

The feeding rhythm is one of the key factors determining success artificial breeding S. paramamosain. To understand different zoea larva developmental stages paramamosain, rate, digestive enzyme activity, and expression metabolism-related genes were investigated in present study. results showed that paramamosain rate has strong diurnal rhythm, being significantly higher at 10:00-14:00 from ZI to ZIV. While peaked 14:00 on Days 10 11, peak shifted 18:00 Day 12. activity enzymes amylase, pepsin lipase decreased night but increased daytime, showing a single-phase similar suggesting was closely associated with during larval development. Compared lipase, amylase most consistent rate. In particular, Due its synchronicity could provide potential reference for best time breeding. Moreover, relative mRNA SpCHH SpFAS tested points lower 10:00 14:00, 6:00 next day. On other hand, patterns SpHSL SpTryp converse those SpFAS.
