Dataset on reproductive status of ovary mud crab at different salinity levels

Abstract

This article investigated how crabs responded to different culture salinities through ovarian maturation stages using combination of external morphology (ovarian coloration and gonadosomatic index), and histological assessment (oocyte structures and diameter sizes). A total of sixty immature crabs were sampled from coastal water of Setiu Wetlands, Kuala Nerus, Terengganu, Peninsular Malaysia, and were introduced to limb autotomy technique in order to induce molt. Crabs were reared until successfully molted, and leaves prior to hardened shell, before proceed with salinities acclimatization prior to salinity treatments (10, 20 and 30 ppt). Five crabs were randomly selected every 15 days throughout 60-day of culture (Day 15, 30, 45 and 60) for the assessment. The different between each ovarian maturation stages was recorded based on the color appearances, and Kruskal-Wallis analysis were done between gonadosomatic index and oocyte diameter sizes with different salinity treatments. Part of the data is associated with the recent articles [1], [2] and provided here as raw data of Supplementary materials.

Potent ovarian development as being stimulated by cocktail hormone in the female Scylla olivacea

“…To investigate the stimulation of ovarian maturation using a combination of hormones, experiments were carried out on mature female mud crabs during the intermolt stage (Kuballa et al, 2011;Xu et al, 2020). All crabs with an average weight of 135 g-145 g, gonad somatic index (GSI) <0.2, and a distance of 85 mm-92 mm between the two tips of the ninth spine of the anterolateral carapace (Amin-Safwan et al, 2016;Ghazali et al, 2017) were used to investigate the effect of hormone administration on ovarian maturation and reproductive gene expression.…”
