Predator-prey interactions are important drivers in structuring ecological communities. However, despite widespread acknowledgement that individual behaviours and predator species regulate ecological processes, studies have yet to incorporate individual behavioural variations in a multipredator system. We quantified a prevalent predator avoidance behaviour to examine the simultaneous roles of p...

Analysis of Production and Revenue Mangrove Crab Pond (Seylla serrata) Tanjung Rejo Village, Percut Sei Tuan District, Deli Serdang Regency”. The purpose this study was to analyze the effect production factors pond area, seeds, feed labor on mud crabs. selection research locations carried out purposively. data collection by distributing questionnaires interviews. sources used are primary second...

Megalopae of many decapod crab species accelerate their development time to metamorphosis (TTM) when exposed to natural physical and/or chemical cues characteristic of the parental habitat. In the present study, the influence of natural settlement cues on the moulting rates and development TTM in megalopae of the fiddler crab Uca vocator was investigated. The effects of mud from different habit...

Colour changes in fiddler crabs have long been noted, but a functional interpretation is still lacking. Here we report that neighbouring populations of Uca vomeris in Australia exhibit different degrees of carapace colours, which range from dull mottled to brilliant blue and white. We determined the spectral characteristics of the mud substratum and of the carapace colours of U. vomeris and fou...

Anti-lipopolysaccharide factors (ALFs), a type of cationic antimicrobial peptides (AMPs), and their derivatives are becoming predominant candidates for potential drugs in viral and bacterial diseases. This study reports the first ALF from the mud crab Scylla tranquebarica (StALF, JQ899453) and the second ALF isoform from the blue swimmer crab Portunus pelagicus (PpALF2, JQ899452). Both sequence...

Mud crab (Scylla spp.) aquaculture has become an important livelihood option for the coastal fisher-folks in Bangladesh. crabs harvested from wild sources are traditionally fattened pens installed tidal rivers, ghers, and earthen ponds The study was aimed at understanding practice production economics of mud farming South-West Sundarbans region Bangladesh, conducted areas namely Bagerhat, Satkh...

The mud crab business is being considered by most marketing operators to be a profitable and sustainable due the high demand in international market. This study aims determine value addition at different actors-based steps; primary data was collected from 100 respondents (40 collectors, 10 fatteners, 20 depot owners, suppliers exporters) who were selected randomly Khulna, Satkhira Dhaka distric...

Abstract This study provides a broad phylogenetic analysis for the Eubrachyura, with inclusion of three new Panopeidae mitochondrial genomes: Eurypanopeus depressus (flatback mud crab) (15,854bp), Panopeus herbstii (Atlantic (15,812bp) and Rhithropanopeus harrisii (Harris, or ‘white-fingered’ (15,892bp). These mitogenomes were analyzed alongside all available brachyuran genomes (n = 113), compr...

The mud crab, Scylla paramamosain, has abundant nutrients in the ovary, where numerous lipids accumulate during ovarian maturation. However, mechanism behind accumulation of ovary crab maturation is largely unknown. This study conducted a comparative transcriptome analysis ovaries crabs at various stages A total 63.69 Gb clean data was obtained, with Q30 93.34%, and 81,893 unigenes were identif...
