Abstract

Cilacap and Kebumen are potential coastal habitat for mole crab such as Hippa adactyla. Ecosystems condition of both locations is distinct. Each organism have to develop adaptation strategy to deal with environmental variation. H. adactyla usually burry into substrate to cope with environmental stress. They have been adapted to local habitat in order to be able for survive and reproduce. However, it has not been well known whether the adaptation strategy may vary the performance of morphology. This study focused on morphological variation of mole crab H. Adactyla. The sample was carried out on August 2014. Mole crabs were caught using traditional fishing gear called “sorok”. They were 118 individuals which where caught in Cilacap, while 102 individuals that were found in Kebumen. The result showed that H. adactyla walk vertically (backwards). These caused by carapace length and carapace width ratio. T-student analysis showed that relative growth for males were negatively allometric and isometric for female in both habitat. Mean of condition factor (K) for males in Cilacap was 0.0319 ± 0.0025 and 0.0315 ± 0.0028 in Kebumen. Those were significantly higher for females (p<0.05) in Cilacap (0.0325 ± 0.0050) and Kebumen (0.0329 ± 0.0027). Mean of relative condition factor (Kn) was higher in Cilacap for males and females. Those variations of K and Kn related to exogenous and endogenous factors.

Abstract

Two species of slipper lobster, Thenus indicus Leach, 1815, and Scyllarides haanii De Haan, 1841, are reported for the first time from the coastal waters of South of Java, part of the Indian Ocean. A total of two specimens, one specimen of T. indicus from Palabuhanratu Bay and one specimen of S. haanii from Yogyakarta coastal waters, were collected in April and September 2015, respectively. Descriptions and illustrations of the morphological characteristics of the two species and their habitat are presented.

Abstract

Swamp eel (Monopterus albus) is an economically important freshwater fish which has the potential to sustainable development. This species is considered as one of the taxonomically problematic spesies due to its complex characters and similar morphology to Monopterus cuchia and Monopterus javanensis that often lead to taxonomic dilemmas. Taxonomic certainty is an essential basis information in sustainable fisheries management, studies on morphometric characters, and genetic variability is a method which commonly used for species or stock identification. This study was aimed to validate the taxonomy certainty and evaluate the kinship of swamp eel from four populations (Indramayu, Subang, Tasikmalaya, and Garut distrik) in West Java. Morphometric analysis was conducted by measurement of 19 characters, whereas genetic analysis was conducted using PCR-Sequencing method of COI gene. The results from stepwise discriminant analysis showed that 7 morphometric characters ratio were powerful to classified the populations and the first two discriminant functions accounted 84.2% of the total variability. Genetic diversity indicated by alignment 14 sekuen of COI gene showed there were 11 haplotypes from 109 variable sites. Results of cluster and phylogenetic tree analysis indicated that swamp eel from four research populations were grouped into two major clusters. The first cluster consists of Indramayu and Subang population, the second cluster consists of Tasikmalaya and Garut population. This cluster is an evidence that swamp eel from West Java possesed morphometric and genetic diversity among populations and lead to assumption that at least there were two cryptic species from M. albus in West Java.

Abstract

This study aims to describe the size distribution of coconut crabs spatially and temporally in Daeo, Morotai Island, North Maluku. The captching was carried out at three stations, namely in areas adjacent to residential areas (station I), steep terrain with varying vegetation (station II), and shallow areas with various vegetation and coconut trees (station III). The collections of samples were conducted using coconut bait and catching directly by hand. Their lengths of cephalotorax plus rostrum (Cp+r) and thorax (TL) and weight were measured. The habitat conditions of natural vegetation were also observed. Data collected in catch (spatial) were analyzed with non-parametric Mann- Whitney (α0.05) and temporal tests with Kruskal Wallis test (α0.05). The results showed that the total numbers of catched coconut crabs were 581 individuals consisted of 314 and 267 males and femalescoconut crabs). The weight ranges of male and female coconut crabs were 50-990 and 50-520 grams, respectively. The ranges of Cp+r on male and female coconut crabs were 43.98-114.72 mm and 43.98-90.67 mm, respectively. The sizes of the TL in male and female coconut crabs were 19.56-54.86 mm and 19.56-48.65 mm, respectively. Non-parametric Mann-Whitney test of the number of spatial coconut crab catched in station I was different from those in station II and stasion III (P<0.05). The numbers coconut crabs catched were not temporally different (P>0.05). The spatial environmental qualities were not different (P>0.05) and the temporal parameters were significantly different (P<0.05) except pH that was not significantly different (P>0.05). Station III had denser vegetation than stations I and II.

Abstract

ABSTRAKBelangkas Tachypleus tridentatus adalah salah satu hewan bentik laut yang menghuni perairan pesisir Balikpapan Timur. Informasi tentang populasi belangkas di lokasi masih terbatas, dan IUCN secara luas mengklasifikasikannya dalam kategori data deficient. Penelitian ini bertujuan untuk menjelaskan kepastian taksonomi secara genetik dan sebaran T. tridentatus di perairan pesisir Balikpapan Timur. Belangkas diperoleh menggunakan alat tangkap nelayan setempat (dogol - sejenis pukat dan jaring insang) di daerah Teritip dan Manggar, masing-masing pada jarak sekitar 1 dan 2 mil dari garis pantai. Pengambilan belangkas dilakukan mulai Januari hingga Maret 2018 pada fase bulan berbeda. Belangkas yang tertangkap dihitung dan dicatat lokasi penangkapannya serta diamati karakter morfologinya untuk analisis sebaran dan sebagian belangkas diambil darahnya untuk analisis kepastian taksonomi dengan menggunakan penanda gen CO1. Karakter morfologi utama berupa telson yang berbentuk segitiga dan duri kecil yang banyak terdapat pada ophisthosoma, secara genetis menunjukkan bahwa jenis yang dikumpulkan adalah T. tridentatus. Sebagian besar belangkas yang ditemukan di lokasi penelitian adalah belangkas dewasa yang menyebar secara acak, dengan lebar prosoma berkisar antara 22,5 hingga 30,5 cm untuk jantan dan 28,5 hingga 37,5 cm untuk betina. Jumlah belangkas terbanyak ditemukan di daerah Teritip dan berdasarkan fase bulan terjadi pada kuarter ketiga. Penelitian ini menguatkan kepastian adanya jenis T. tridentatus di lokasi penelitian dengan ciri yang mudah dikenali serta konektivitas pergerakan T. tridentatus ke lokasi lain di sekitar perairan Balikpapan Timur. ABSTRACTThe tri-spine horseshoe crab Tachypleus tridentatus is one of marine benthic animals inhabiting East Balikpapan coastal waters. Information on horseshoe crab population in the location is still limited and IUCN broadly classifies the crab in deficient data category. This study was aimed at elucidating the taxonomic certainty genetically and distribution of T. tridentatus in coastal waters of East Balikpapan. The crabs were collected by local gear of fisherman (dogol – a trawl like fishing-gear and gill net) in the Teritip and Manggar areas, each at a distance of 1 and 2 miles from coastline. Collecting takes place between January to March 2018 at different moon phases, location, number and morphological characters of the crabs was recorded and blood was taken from some individuals. Primary morphological characters in the form of triangular shape of telson and abundant tiny spines on ophisthosoma, genetically ascertained that the collected crab is T. tridentatus. Most of these crabs found was adult and randomly dispersed; with the width of prosoma ranged from 22.5 to 30.5 cm for males and 28.5 to 37.5 cm for females. The highest number of crab was found in the Teritip area and in the third quarter moon phase. This study reinforce the certainty of T. tridentatus in the study site with easily recognized morphological characters and the connectivity with other sites around Eastern Balikpapan waters.
