Agonistic behavior of captive saltwater crocodile, crocodylus porosus in Kota Tinggi, Johor

Agonistic behavior in Crocodylus porosus is well known in the wild, but the available data regarding this behavior among the captive individuals especially in a farm setting is rather limited. Studying the aggressive behavior of C. porosus in captivity is important because the data obtained may contribute for conservation and the safety for handlers and visitors. Thus, this study focuses on C. porosus in captivity to describe systematically the agonistic behaviour of C. porosus in relation to feeding time, daytime or night and density per pool. This study was carried out for 35 days in two different ponds. The data was analysed using Pearson’s chi-square analysis to see the relationship between categorical factors. The study shows that C. porosus was more aggressive during daylight, feeding time and non-feeding time in breeding enclosure (Pond C, stock density =0.0369 crocodiles/m2) as compared to non-breeding pond (Pond B, stock density =0.3317 crocodiles/m2) where it is only aggressive during the nighttime. Pond C shows the higher domination in the value of aggression in feeding and non-feeding time where it is related to its function as breeding ground. Chi-square analysis shows that there is no significant difference between ponds (p=0.47, χ2= 2.541, df= 3), thus, there is no relationship between categorical factors. The aggressive behaviour of C. porosus is important for the farm management to evaluate the risk in future for the translocation process and conservation of C. porosus generally

The educator's perspective: knowledge, attitude and practices on occupational safety and health at school among primary and secondary school teachers

Introduction: School can be considered as a relatively moderate risk working environment due to the various hazards assembled in the school. Nevertheless, Occupational Safety and Health (OSH) training is yet to formally inclusive into teachers’ training module, and the current one-off or ad-hoc OSH training mainly targeted among school students. The different OSH awareness exists among teacher and student have hinder the provision of sustainable and effective safety and health training program at school levels. Objective: To assess the knowledge, attitude and practice among primary and secondary school teachers towards OSH at the school environment. Method: A cross-sectional survey carried out at three (3) primary schools and three (3) secondary schools after stratified random sampling. School teachers from these schools were randomly selected among those who had at least one year work experience as permanent teacher at the current school through the fishbowl technique. A structured questionnaire was used and total 136 teachers were assessed on their knowledge, attitude and practices on OSH at schools. Result: Study found that primary and secondary school teachers have different knowledge, attitude and practices of OSH at school levels. Overall, the knowledge level of secondary school teacher (62.1% of high to medium knowledge levels) are higher than the primary school teachers (41.1% of high to medium knowledge levels); at the same time, 93.1% of secondary school teachers show positive attitude while 88.5% of primary school teachers show positive attitude on safety and health at schools. In general, OSH practice level among the primary (88.5%) and secondary school teachers (86.2%) are at relatively good levels. Besides, there is positive association with knowledge and attitude on OSH behavior among primary school teachers. Apart of this, there is positive but relatively weak association with knowledge and practices and knowledge and attitudes among primary and secondary school teachers. Conclusion: Considering the background differences between primary and secondary school teachers, a sustainable OSH learning mechanism should be planned and designed together with OSH practitioners and Ministry of Education to achieve a sustainable safety and healthy sound school environment for teacher to work and for students to learn

Data on first record of brown morph banded langur (presbytis femoralis), leucistic dusky leaf monkey ( trachypithecus obscurus ) in Malaysia and review of morph diversity in langur (colobinae)

Morphism refer to polymorphic species, in which multiple colour variants coexist within a population. Morphism in pri- mates is common and langurs also exhibit certain character- istics of morphism, such as conspicuous natal coats. Banded langurs ( Presbytis femoralis ) and dusky leaf monkey ( Trachyp- ithecus obscurus ) exhibits the same characteristics of conspic- uous natal coats, but these coats are only limited to infants and changed when they reached adulthood. This article re- ports the first discovery of rare brown morph of two adult male banded langurs and one leucistic adult female dusky leaf monkey in Malaysia. We also conducted a systematic literature search to review the diversity of morphism in leaf monkey globally

Feeding Regime and Management of Captive Saltwater Crocodile, Crocodylus Porosus in Kota Tinggi, Johor

Crocodylus porosus is the largest species of crocodile and can be found in estuarine and riverine area in Malaysia. Crocodile in captivity can be found in Malaysia for various purposes such as tourism, conservation and leather industry. However, the management practice in established crocodile farm varies across park for example in terms of feeding regime. Thus, this study focusses on the feeding regime of C. porosus in captivity and evaluation of management of crocodile of Teluk Sengat Crocodile Farm. This study was carried out for 35 days in two different ponds of Teluk Sengat Crocodile Farm, Kota Tinggi, Johor. The results show majority of the food given to crocodile were chicken (64%), followed by fish (28%) and prawn (8%). Prawn was only given to juvenile crocodile every day, while fish and whole chicken were given to adult crocodile once a week. The feeding frequency are adequate for the juvenile crocodile however, the feeding quantity for adult pond are worrying. Future research should be conducted on other captive population of C. porosus in other areas in Malaysia as well to better understand the overall management practices in Malaysia

DNA Barcoding of Commercial Fish Sold in Muar Fish Market, Johor

Due to the high demand in the fisheries market, species identification is vital for commercial fish to avoid mislabeling and fraud in marketplaces. The increasingly threatening human activities like overfishing, blast fishing, poison fishing, and trawling have become the major threats to fish and caused an urgent need for documentation of both marine and freshwater fishes. Commercial fish products sometimes are sold by their parts, such as fins which further create confusion for identification purposes. Morphological identification also requires highly skilled ichthyologists to avoid misidentification. Thus, identification through DNA barcoding can be utilized as it holds the potential for accurate and rapid identification. Here we identified the commercial marine fish species sold in Muar Fish Market, Johor, using the Cytochrome Oxidase subunit I (COI) gene of mitochondrial DNA (mtDNA). A 700 base-pair sequence of the COI region was targeted by amplifying extracted DNA from 28 fin samples collected from the fish market. From 28 samples, we successfully sequenced 16 samples, and by using phylogenetic analysis, (Neighbor-Joining (NJ), Maximum Parsimony (MP) and Bayesian Inference (BI)) we successfully identified the samples belonging to nine families (Scombridae, Platycephalidae, Carangidae, Ariidae, Polynemidae, Coryphaenidae, Sphyraenidae, Muraenesocidae, Engraiulidae), 12 genera and 16 species. This study reports the first documentation of commercial fish sold in Muar through the DNA barcoding technique. This technique should be expanded further to identify any species with important conservation implications, such as endangered species, for improved management of fisheries in Malaysia

Preliminary Ethnoichthyological Assessment: Fish Consumption Patterns among Orang Asli Semelai (Aborigines: Proto-Malay) in Tasek Bera, Pahang

Ethnoichthyology, as a field of study, examines the indigenous knowledge held by ethnic groups concerning different fish species. Despite its significance in understanding traditional fishing practices and cultural connections to aquatic resources, data on fish species consumption among the Orang Asli Semelai community remain limited. Therefore, this ethnoichthyological preliminary study aims to address this research gap by documenting the fish species utilized by the Orang Asli Semelai in the Tasek Bera region of Pahang, Malaysia. To achieve this objective, a comprehensive survey and interview session were conducted with a small sample size of four randomly chosen respondents. The study identified 15 fish species solely consumed as food by the community. The most commonly consumed fish species were the Climbing Perch (Anabas testudineus) and Snakehead Murrel (Channa striata). Additionally, the study revealed the presence of the Critically Endangered Jullien's Golden Carp (Probarbus jullieni) among the consumed species, indicating the urgent need for conservation efforts. The findings underscore the significance of integrating sustainable fishing practices and conservation efforts to protect the unique ecosystem of Tasek Bera and preserve the cultural heritage of the Orang Asli Semelai community. Further comprehensive studies and collaborative approaches are vital to safeguarding the region's aquatic biodiversity and ensuring the community's food security sustainably

Preliminary Assessment on Primate Diversity and Potential of PrimaTourism Among Local People and Orang Asli Jakun (Aborigines: Proto-Malay) in Tasik Chini Biosphere Reserve, Pahang, Malaysia

PrimaTourism is a well-known aspect of nature tourism that provides valuable benefits for the primate species conservation. Malaysia, with its rich diversity of more than 25 primate species inhabited in the country, holds significant potential for enhancing primate-based tourism. However, the information on primate species in potential tourism spots like Tasik Chini remains limited, with only a few data on their behaviour and ecology. Additionally, the lack of comprehensive information on the primate species poses challenges in identifying potential PrimaTourism product. Thus, this study aimed to assess primate diversity and explore the perception of PrimaTourism among local people in Tasik Chini. A survey and interview session were conducted over five days in two villages around Tasik Chini (Kampung Gumum and Felda Chini), involving a total of 32 respondents. Most respondents reported the presence of two common primate species in their area: the long-tailed macaque (Macaca fascicularis) and the pig-tailed macaque (Macaca nemestrina). The result suggested a significant majority (81%) of respondents expressed support for the dusky leaf monkey (Trachypithecus obscurus) as an ideal primate species for PrimaTourism in Tasik Chini, citing its attractive coloration and favoring the development of primate-based tourism. Overall, these findings can serve as essential baseline data for implementing primate tourism in the area, engaging the local community to attract tourists to Tasik Chini effectively and eventually serve as a conservation tool for the primate species.

A review on next-generation wildlife monitoring using environmental DNA (eDNA) detection and next-generation sequencing in Malaysia

The use of environmental DNA (eDNA) as the genetic tool to monitor biodiversity has been increasing across the world, including Malaysia. Over a decade, the technique has become widely used in wildlife conservation with the technologies called next-generation sequencing (NGS). Unfortunately, as one of the top megadiverse countries, Malaysia is still behind in this field since eDNA methods outperform traditional surveys. Hence, in this study, we analyzed the paper related to eDNA studies in Malaysia, which focused on wildlife monitoring. We conducted a systematic bibliographic search and quantitative review of studies published before June 2021 from Google Scholar and Scopus database. Forty published eDNA studies were found, and each paper was classified based on five themes (species identification, diet assessment, health monitoring, resolve taxonomic, whole-genome sequencing) according to the study analysis. This study aims to identify gaps in eDNA in Malaysia, which can later be useful for future conservation actions and development by applying technology in wildlife monitoring
