Characterising mitochondrial genomes is a key to studying evolution in vertebrates including turtles. This study employed Next-Generation Sequencing (NGS) to characterise mitochondrial DNA sequences in Batagur borneoensis (Schlegel & Muller, 1844). We reported the nearly complete mitogenome to clearly characterise the gene sequence of B. borneoensi...

The Painted Terrapin ( Batagur borneoensis ), a critically endangered freshwater turtle in Malaysia, is facing rapid decline due to adult and egg harvesting for food and habitat loss from beachfront development. This study aimed to assess genetic diversity in random nesting sites along the Setiu River. Mitochondrial DNA (mtDNA) from saliva samples...

In total, 13 species of Caligus have been reported from Malaysia. Amongst them, four species are reported from lutjanid fishes. Caligus dussumieri Rangnekar, 1957 is reported from Malabar snapper, Lutjanus malabaricus , purchased from a local wet market in Terengganu, Peninsular Malaysia. This is the first record of this species in Malaysia and it...

Freshwater invasive alien species (IAS) are non-native organisms that were intentionally or unintentionally released into local water bodies and later harmed the invaded habitat by disrupting the ecological processes. Over the last few years, environmental deoxyribonucleic acid (eDNA) analyses have been used in many studies to detect IAS, with posi...

Peacock bass (Cichla spp.) is an invasive fish that has established feral population in many freshwater water bodies in Malaysia. Among the negative impact of invasive species are the co-introduction of new parasites, and they also may act as vector to various disease causal agents. The aim of this study was to identify and to measure the prevalenc...

The redclaw crayfish had been listed as an invasive species in Malaysia following the various negative impacts displayed on both environment and economy. The species are largely culture in Malaysia for food, but unluckily escaped and expands to several waterbodies across the country. For effective control management of redclaw crayfish species, a t...

There have been reported around 11 aquatic invasive alien species (IAS) found in Malaysian waters. Cherax quadricarinatus , or commonly known as Australian redclaw crayfish, is one of the invasive species. C. quadricarinatus has the potential of causing negative impacts ecologically and economically in the local environment as it has reported in se...

The redclaw crayfish (Cherax quadricarinatus) is an aquatic species native to the northern Australia and southern New Guinea. The invasion of this species worldwide was mainly associated with the aquaculture activities, ornamental pet trading and deliberate or unintentional release into the wild. This review highlighted the first report, distributi...

Australian redclaw crayfish, Cherax quadricarinatus, is a species of crayfish native to northern Australia and southern New Guinea but has been introduced and established feral population in many parts of the world including in Malaysia. In this present study, we examined some morphometric characteristics of C. quadricarinatus collected from three...

A sector of broiler production is growing very fast to meet the high demand of meat in Nigeria. However, high mortality rates among the broilers especially during the hot dry season in arid and semi-arid zones is worrisome. There is a need for molecular genetics study that could aid in management, conservation and sustainable exploitation of this s...

Six individuals of Australian redclaw crayfish Cherax quadricarinatus (von Martens, 1868) (Decapoda: Parastacidae), the identity of which was confirmed through morphological and molecular characterization. They were caught from the wild environment in Terengganu, East Coast of Peninsular Malaysia. Since there is no record of redclaw aquaculture in...

Malaysia is recognised among the mega-diversity countries with the abundance of various freshwater species. Malaysian freshwater biodiversity is under threat after the introduction of an invasive peacock bass. The presence of this predator could challenge the coexistence of the native species. In the current review, the most important aspects regar...

A study was conducted to determine the tree species composition and species diversity at Compartment 4 of Sungai Udang Forest Reserve, Malacca. A total of 1668 individual trees with diameter at breast height (DBH) of 5 cm and above were found in the 25 plots in Sungai Udang Forest Reserve, Malacca, Peninsular Malaysia of which overall floristic com...

Invasive peacock bass Cichla spp. have recently invaded freshwater habitats across Malaysia. Stomach contents of 135 peacock bass captured from the Telabak Lake of East Coast of Peninsular Malaysia were analysed. The preys were examined using visual identification method and mitochondrial DNA barcoding technique to identify the partial digested and...

Both sexes of Brachiella malayensis n. sp. are described on the basis of specimens found in the nostrils of narrow-barred Spanish mackerel Scomberomorus commerson (Lacepède) collected off Besut, Malaysia. The female of this species closely resembles those of B. magna Kabata, 1968 and B. cybii Pillai, Prabha et Balaraman, 1982 but is distinguishable...

Peacock bass (Perciformes, Cichlidae, Cichla) are multi-coloured and highly predatory fish originated from Amazonian region. The species was deliberately introduced into Malaysia freshwater bodies by anglers in the early 1990’s for sport fisheries. In this recent study, we found the population of peacock bass in Lake Telabak, a man-made lake in Bes...

This paper attempts to provide a preliminary checklist of mangrove species in Sungai Kong Kong, Selat Medana, Johor. The results presented were taken from the sampling at Sungai Kong Kong. After being pressed, dried and mounted on herbarium sheet, the specimens were made into herbarium voucher. Of the 26 species, Rhizophora apiculata and R. mucrona...

This study was conducted to determine the effect of dietary probioticon intestinal and fecal microflora and carcass yield of broiler quails during the four weeks of feeding period. The quails were fed a basic diet (group 1) which acted as the control group; another 3 groups were fed basal diet with probiotic added at concentrations of 0.05%, 0.20%a...
