“…However, in T2 (2 h), there was a lower significance for scale A4 (ꭓ 2 = 2.6734), whereas, in T3 (24 h), no aggressiveness behavior was recorded in scale A4, which corresponds with what was reported by Xiao-Zhen et al (2019). In the male-female bioassay, there were significant differences in T2 (2h) among treatments (ꭓ 2 pool = 63.8570; ꭓ 2 critical = 30.612; P < 0.05), being the significance for scale A1 the highest (ꭓ 2 = 38.0886), in this experiment no records of organisms with the mutilation of the body part (A3), nor confrontation between crabs causing death (A4) were registered, which indicates that in the bioassay of males-females, aggressiveness decreases as the crabs were in close contact among themselves (copulation).…”

“…Aggressiveness is an important aspect that should be considered in managing breeders in aquaculture conditioning (Taylor et al 2004, Xiao-Zhen et al 2019). In the present study, aggressiveness was evaluated using a behavioral scale (A0 to A4), in which there were significant differences between the aggressiveness scales in the ablation treatments concerning the control treatment (P < 0.05), with greater activity in levels A0 to A2, which consisted of aspects such as "confrontation among crabs without touching each other", prickling among crabs and chelae releasing", "subjection for a short period" (Table 1).…”

“…shelter, food, mating opportunity, and mating territory) factors. Different pairwise tests, including male-male, malefemale and female-female, display different fighting abilities (Taylor et al 2004, Dissanayake et al 2009, Xiao-Zhen et al 2019, considering this, in the crab C. arcuatus (Table 3) in the bioassay with males, in time T2 (2 h) there were significant differences between the aggressiveness scale (A0-A4) for the control, ST and LT treatments (ꭓ 2 pool = 104.1034; ꭓ 2 critical = 30.612; P < 0.05), particularly in scale A1 where a high significance was observed (ꭓ 2 = 37.0062). Concerning the bioassay with females, in T0 (10 min), there were significant differences (ꭓ 2 pool = 43.7138; ꭓ 2 critical = 30.612; P < 0.05) among treatments, where the scale A4 recorded the highest significance (ꭓ 2 = 21.00) in comparison with other aggressiveness in T0.…”

Eyestalk ablation allows the removal of neurohormones that inhibit early reproduction and decreases the time to complete the molting cycle. The present study evaluated the impact of unilateral eyestalk ablation on the behavior of blue crab breeders Callinectes arcuatus in the short term under laboratory conditions. Immature male and female crabs and individuals in the intermolt stage were collected in Ohuira Bay, Ahome, Sinaloa, Mexico. Three bioassays were performed: males, females, and male-females each with three treatments; control + xylocaine (50 μL, 5%), squash ablation + xylocaine (50 μL, 5%), ablation by string ligation + xylocaine (50 μL, 5%), each with three replicas and three periods of evaluation after the ablation procedure (10 min, 2 h, and 24 h). Kruskal-Wallis and Chi-square (χ2) tests were used to evaluate significances (P < 0.05) in the behavior of C. arcuatus. The sizes of blue crab C. arcuatus were 9.72 ± 1.0 cm of carapace width. The feeding behavior of the male-females bioassay was significant at 2 h (P < 0.05). The results obtained were satisfactory using two techniques, unilateral eyestalk ablation by squash and ligation in which pain and aggressiveness indicators were mitigated. Disorientation and aggressiveness in males were significant at 2 h (P < 0.05), and in females after 10 min, and 2 h after ablation (P < 0.05). In the male-females bioassay, aggressiveness was significant at 2 h (P < 0.05). Courtship and copulation were recorded in those crabs subjected to unilateral eyestalk squash ablation (13 and 8, respectively).

“…Therefore, many scholars believe that L-trp-induced 5-HT activity is involved in mediating many physiological and behavioural processes, such as feeding, stress sensitivity and aggressive behaviour (Harlıoğlu et al, 2014;Laranja et al, 2010;Sève, 1999). Studies on 5-HT and 5-HT agonists have shown that 5-HT influences aggressive behaviour in crustaceans, such as Astacus astacus, Procambarus clarkii and Orconectes rusticus (Huber & Delago, 1998;Tierney et al, 2004;Tierney & Mangiamele, 2001), as well as E. sinensis (Yang et al, 2019).…”

This study was designed to evaluate the effects of dietary L-tryptophan (L-trp) supplementation on growth performance, feeding and digestion, 5-HT levels and the related receptor expression levels of Eriocheir sinensis. In this study, crabs were divided into four groups: the analysed tryptophan concentrations were 3.6 (Diet #A), 4.7 (Diet #B), 7.3 (Diet #C) and 10.5 (Diet #D) g/kg dry matter, respectively. In Trial 1, we found that there was no significant difference in the growth parameters (weight gain rate, carapace length increase rate, carapace width increase rate and hepatopancreas index) among the four dietary groups after 30 days, whereas the molting rate was significantly higher in the Diet #C group and the limb autotomy rate was significantly lower in the Diet #C group than in the Diet #A group (p < .05). Moreover, trypsin activity and lipase activity were significantly improved. In Trial 2, we found that dietary L-trp supplementation after 7 days significantly increased the feeding rate and motor behaviour duration of E. sinensis. In Trial 3, we found that 5-HT levels in haemolymph increased dose dependently with dietary L-trp supplementation and were significantly higher in the Diet #D group than in the Diet #A group (p < .05). Moreover, the expression trends of 5-HT 1BR in the hepatopancreas, thoracic ganglia and cranial ganglia; 5-HT 2BR in the thoracic ganglia; and 5-HT 7R in the hepatopancreas, intestine and cranial ganglia were similar to the change trend of 5-HT levels. In conclusion, dietary L-trp supplementation was beneficial for molting cycle and can significantly improve food intake and digestive enzyme activities possibly by mediating 5-HT and binding to its related receptors, which will provide new insights into the physiological functions of L-trp in E. sinensis.

“…Agonistic behavior is a common phenomenon in crustaceans and usually decreases the crabs' integrity, survival, and growth (Laranja et al, 2010;Harlıoglu et al, 2013;Romano and Zeng, 2016). In our previous studies, we reported the agonistic behavior of E. sinensis and further investigated the regulation of serotonin (5-HT) and dopamine (DA) in agonistic behavior through the cAMP signaling pathway (Pang et al, 2019a;Yang et al, 2019). First, we had divided the agonistic behavior in E. sinensis into three stages: approach, contact, and fight; and then, we found a sign in the concentration of 5-HT, DA, cAMP, and PKA after agonistic behavior (Yang et al, 2019).…”
