Spiny lobsters of the family Palinuridae Latreille, 1802 are known to be industrial crustaceans in the global fishing market amongst other crustacean marine species. Panulirus femoristriga has been reported in the Maldives, Japan, Taiwan, Vietnam, the Philippines, Indonesia (Ambon, Irian Jaya, Celebes Island, Seram Island), the Polynesian Islands, Solomon Islands, New Hebrides, Wallis and Futuna and off the coast of northern Australia, but there is uncertainty about their distributions due to the morphological similarity with Panulirus femoristriga, Panulirus longipes bispinosus and Panulirus brunneiflagellum. However, the identification on P. femoristiga can only be confirmed if the morphological descriptions are mentioned in literature. A specimen of the spiny lobster Panulirus femoristriga Von Martens, 1872 was discovered in Semporna, located on the west coast of Sabah State, Malaysia Borneo. While the status of P. femoristriga has been classified as "least concern" on the International Union for Conservation of Nature Red List, studies on the species' population size, habitat and distribution are still inadequate. This study adopted both morphological and molecular approaches for species delimitation.The phylogenetic position of the Sabah P. femoristriga was revealed by the mitochondrial cytochrome c oxidase gene (COI) marker. This represents the first record of the species in the coastal waters of Sabah, despite its wide geographical distribution in the Indo-West Pacific. A revision on the species global distribution was also conducted by harvesting all literature with species named Panulirus longipes femoristriga and Panulirus femoristriga which were available online including those prior to year 2001 before the presence of P. femoristriga is confirmed. Due to the uncertainties on the morphological distribution in previous literature, further studies are required to fill in the missing data for confirmation.

Limited info regarding on the global distribution and fisheries data on the spiny lobster Panulirus spp. had placed the IUCN redlist in a dilemmatic position in determining the concrete status for proper conservation. The present survey was carried out in the western region of the main island which consists of seven random stations along the west coast of Labuan during day dive. An extreme low density of the spiny lobsters from the genus Panulirus was determined throughout the present study. Only four individuals of two spiny lobsters species were recorded. Two individuals of P. versicolor were observed in station 2 while the other two (P. ornatus) were spotted in station 4. Low numbers of the Panulirus spp. were spotted during the present preliminary survey was probably due to day dive sampling. Spiny lobster from the genus Panulirus tend to have a wide range of depth preference. Two adults P. versicolor were spotted in least turbid environment. In the previous studies, Panulirus spp. such as P. homarus, P. ornatus, and P. polyphagus tend to prefer slightly turbid environment. The results of the present preliminary daytime survey indicated only two species of Panulirus spp. recorded with two individual numbers per species in Labuan coastal waters. However, due to the little numbers of catchment during the preliminary survey, further studies need to be carried out to provide more concrete evidences on the depth preference of Panulirus spp. in Malaysian waters.

The study was conducted to assess the effect of mulberry leaves extract (Morus alba) on the growth rate of giant freshwater prawn, Macrobrachium rosenbergii. In the present study, the mulberry leaves extract was mixed with commercial pellets using the spray method; pellets with 5 % and 10 % mulberry leaves extract. Meanwhile, the control treatment was a commercial pellet with no mulberry leaves extract. M. rosenbergii were fed with the experimental pellets for 30 days and each treatment had 10 tails of M. rosenbergii juveniles. The result showed that the juveniles fed with pellet with 10 % mulberry leaves extract had the highest survival rate and the total number of moulting. As a conclusion, the mulberry leaves demonstrated a good effect on the growth of M. rosenbergii and reduced the mortality rate, thus, the present study suggests the use of mulberry extract as a potential nutrient supplement in the feed to increase the production of M. rosenbergii post-larvae.
