Horseshoe crabs are currently threatened by escalating human stresses along the Indo-Pacific coastline. Conservation of their remaining populations, however, is hindered limited baselines throughout ranges. We performed a questionnaire survey conservation experts from diverse geographic regions to identify baselines, prominent threats, impediments and alternative strategies that prioritize Asian horseshoe crab conservation. Despite long-term monitoring across habitat types lacking, local...
Isolation of chitin and chitosan from natural sources are widely known as they can be used in many applications.Extraction carried out exoskeleton flower crab, Portunus pelagicus.Chemical treatments such demineralization deproteinzation processes for extraction, followed by deacetylation process chitin, which is to produce its derivatives that chitosan.Characterization has been done using Fourier Transform Infrared (FTIR) Spectroscopy, X-ray diffraction (XRD), CHNS elemental analysis...
This study was carried out to determine the physiological changes (survival, growth, molting cycle, sex differentiation, and gill condition) of mud crab, Scylla paramamosain crablet at different water temperatures 24, 28 32 °C, ambient temperature 27 30 °C. Thermoregulatory behavior, represented by preferred (29.83 ± SD 2.47 °C), critical thermal minimum (17.33 0.58 maximum (40 0.00 tolerance interval (22.67 were checked for Crablet 1 stage only (with as acclimation temperature).Both low (24...
The dwindling number of the tri-spine horseshoe crab, Tachypleus tridentatus has been reported globally and its status in Malaysia is not much known. Study on dimorphism adult body sizes population size estimation were conducted using capture–mark–recapture method T. Tawau, Sabah. Camry estimated ranged from 182 to 1095 with 95% confident limits 56–42,942 individuals (Schnabel formula). multivariate discriminant Hotelling's T2 test verifies sexual among 97.7% separation sexes (Hotelling's =...
Abstract Horseshoe crab populations are declining worldwide, and Tachypleus tridentatus (Leach, 1819) has recently been classified as Endangered in the IUCN Redlist. Among keys for species survival is successful reproduction. Although there reports on reproduction, particularly details spawning behaviour, of American species, Limulus polyphemus (Linnaeus, 1758), information Southeast Asia very scant. This field study nesting activities T. at Jambongan Island, Sabah, Malaysia. Observation...
A double green approach to the synthesis of silver nanoparticles using chitosan as a reducing agent and microwave radiation has been carried out in this study. Chitosan was extracted from marine crab carapace morphology produced characterized Scanning Electron Microscope (SEM). The production (AgNPs) monitored by formation surface plasmon resonance (SPR) at λmax= 420 nm, indicates reduction oxidation state Ag+ Ag0. XRD data confirms crystallinity nature obtained AgNps, while SEM TEM revealed...
Due to limited availability of literature on the spawning activity Malaysian horseshoe crab, Tachypleus gigas (Muller, 1785), reproduction behaviour and biology this arthropod remains poorly understood. Hence, an investigation was carried out from April-July trail crab amplexus at Balok Cherating, only known T. grounds east coast Peninsular Malaysia. Through visual tracking during daytime full moon spring tides, release air bubbles indicate nest digging by female crabs. While bubble...
The Setiu Wetlands, a unique area with nine interconnected habitats, comprises considerable fraction of the total Peninsular Malaysia’s wetland flora. Although botanical collecting in has been active past 10 years, only few studies dealing flora have published. Thus, detailed checklist this is urgently needed to ensure continuity its inter-relating and fauna, as well livelihood local people. In work we conducted survey vascular plant Wetlands investigated most important plants used by...

Context Spawning beaches are important for coastal horseshoe crabs, Tachypleus gigas (Müller, 1785), to sustain their population. Over time, T. natural spawning area has gradually diminished owing human and causes. is being artificially bred in captivity enhance its Aims The study aims determine the preference three different sediment sizes. Methods experiments were carried out an indoor concrete tank representing artificial ground, consisting of combinations sizes: coarse, medium fine. 45...
The aquafeed development has been initiated for horseshoe crabs in captivity. However, much of the attentions were to juveniles their widely used research. Until recently, research had incorporated adult crabs. This study aims 1) determine best alternative feeds males Carcinoscorpius rotundicauda, 2) measure acceptance rate feed, and 3) feeding utilization. Three semi-moist pellets either developed or purchased: fish (Decapterus russeli) cockle (Anadara granosa) (A), (B) keropok (C). Natural...

Abstract The information and status of the avifauna community that resides in Tasik Meranti, Wang Kelian, Taman Negeri Perlis are mostly outdated since last survey conducted was 20 years ago. Therefore, study aims to update establish a checklist compare bird species present within vicinity Perlis. during short expedition held on 15-18 August 2019. Based field observation, total birds from 14 families were recorded. recent recorded an additional 18 8 families, totalling current inventory 45...
