Abstract

Tripneustes gratilla an important ecological role in various habitats because T. gratilla is directly or indirectly recycling key from the nutrients in the waters of Ambon Island. Ambon Island has a distinctive topography, thus causing inhibition of water exchange period naturally in Ambon Bay and feared to complicate the exchange of genes between populations thus causing inbreeding. In addition the increasing environmental pollution can narrow the habitat of Tripneustes gratilla. Therefore, this study aims to determine the spatial distribution and genetic diversity of sea urchins (Tripneustes gratilla) on Ambon island based on cytochrome c oxidase subunit 1 gene. Alignment results showed the presence of genetic variation of T. gratilla on the Ambon island. This is shown in several polymorphic base where there has tranversi experience, transition, and insertion. COI gene sequence similarity values of T. gratilla on Ambon island is around 98.4 to 100%. Distribution of T. gratilla population found on Ambon island generally have a relatively small number of individuals. From four locations that just only one location have large enough number of individuals. However, the results of genetic analysis using COI gene showed the presence of genetic closeness between T. gratilla despite located in different locations.

Abstract

Cenderawasih Bay has extremely high biodiversity with an enormous amount of endemic species due to geography isolation. Tripneustes gratilla is one of the species that is abundant in the bay. The species has ecological value that is suitable for bio-indicators of the environmental condition. Since the Bay relatively isolated area, then we examined the impact of the geographical conditions on genetic diversity and connectivity of Tripneustes gratilla among populations in the region surrounding Cenderawasih Bay based on the mitochondrial cytochrome c-oxidase-1 gene. Results of the study showed that genetic variation of the species within the population is high; despite the genetic variation among populations was low. The data suggested that the entire population of T. gratilla were closed connected, homogeneous, and shared polymorphic profile. Then we assumed the gene flow occurred for a long time among populations without geographical barriers. This information is a warrant to develop an effective strategy to maintain biodiversity in the Cenderawasih Bay.

Abstract

Bulu babi adalah hewan Avertebrata laut yang kaya manfaat. Organisme yang tergolong dalam kelas Echinoidea ini dapat dimanfaatkan sebagai sumber pangan bergizi (Darsono & Sukarno, 1993; Nontji, 2002), berguna dalam ekologi (Lawrence, 1975; Lang & Schroeter, 1976), dan bernilai ekonomis penting. Bulu babi juga berfungsi sebagai organisme hiasan dan digunakan dalam bidang kesehatan untuk pengobatan penyakit (Angka & Suhartono, 2000). Beberapa ahli menggunakan bulu babi sebagai salah satu organisme paling populer untuk mempelajari biologi reproduksi (Vacquier et al., 1995), embriologi (Davidson et al., 1998; Lee et al., 1999), toksikologi (Dinnel et al., 1989), regulasi gen (Davidson et al., 2002), dan biologi evolusi (Peterson et al., 2000).

Abstract

The purpose of this study was to determine the level of diversity and genetic relationship of Panulirus versicolor lobsters in Cenderawasih Bay and Lombok waters based on the cytochrome oxidase I (COI) gene. The results showed the level of genetic diversity of the two populations was very high and generally did not differ greatly between populations. We identified 6 haplotypes for P. versicolor lobster populations from Cenderawasih Bay and 7 haplotypes for P. versicolor lobster populations from Lombok waters. Network analysis shows that several P. versicolor lobster individuals from the Cendeawasih Bay and Lombok waters had similar haplotypes. The population of Cenderawasih Bay with Lombok waters was closely related to the average genetic distance value P-distance 0.005 (s.d 0.001) and the results of phylogenetic tree reconstruction showed that the two populations of P. versicolor lobsters form a monophyletic clade (close relatives).

Abstract

Tripneustes gratilla is economically important, supports small-scale, commercially important, ecological values, a prospect as a biological control agent and also considered as the commercially traded sea urchin. We review genetic aspects of T. gratilla for understanding the status to the sustainable use in the future. In GenBank, there are 267 nucleotide sequences related with T. gratilla. Most of the sequences (189 sequences) are COI gene of T. gratilla from Indo-Pacific Ocean. Study on molecular genetics mentioned that there is no genetic structure for T. gratilla distribution in Indo-Pacific Ocean including in Indonesia waters.

Abstract

The mangrove forest is an environment that is very rich in nutrients and it becomes an important element for plankton growth. This article aims to determine the diversity and abundance of plankton species in the mangrove area. The method used in this writing is a literature study, by exploring written sources in the form of books, articles, journals, or other documents relevant to the problem being presented. The information obtained from the literature study can be used as a reference to strengthen the existing arguments. The results of the writing show that the abundance and diversity of plankton in mangrove waters are strongly influenced by the physical and chemical conditions of the water, local conditions, tides, zoning, and mangrove density. In general, phytoplankton from the Bacillariophyceae class dominate mangrove waters compared to zooplankton. A mangrove forest management strategy needs to be implemented so that it can function for organisms and the surrounding environment.

Abstract

The Cenderawasih Bay is a marine habitat for whale sharks (R. typus) which appear almost all year round. The appearance of this whale shark is triggered by various factors, including the food. Anchovy is one of the attractions for the emergence of whale sharks, so it is necessary to conduct genetic, biological and ecological studies. Anchovy has a small in size, making it difficult to identify morphologically. The purpose of this study was to genetically identify anchovy samples obtained from Cenderawasih Bay and compare the sequences with the GenBank database. The COI gene fragments were amplified by PCR method, using primer jg-LCO and jg-HCO. Sequencing is carried out from two directions, forward and reverse with the sanger termination dideoxy method. The resulting DNA sequence has a length of 669 base pairs encoding 223 amino acids. The results of homological comparisons with the NCBI and BOLD System databases show that this sample has similarities to the COI sequence of Spratelloides gracilis with a similarity number up to 99%. The results of the phylogenetic tree analysis showed that the anchovy samples from Cenderawasih Bay were in one clade with S. gracilis from Japan and separated from the clade of S. gracilis from the Red Sea, with a distance between clades is 0.104. This result is in line with the identification by homological comparison in the NCBI and BOLD System.

Abstract

This study aims to determine the distribution of length to weight, sex ratio, gonad maturity level of julung fish (Hemiramphus lutkei) traded in Sanggeng and Borobudur Manokwari fish markets, West Papua. Research data collection was carried out for ± 1 month, namely February - March 2021, using a descriptive method. The number of fish samples collected was 542 fish. The results of the analysis of the size distribution of julung-julung fish during sampling for body length ranged from 219 – 355 mm for males and 215 -380 mm for females, with a body weight range of 27-53 grams for males and 30-65 grams. The sex ratio analysis of julung julung fish was obtained for males (321 fish) and females (221 fish) significantly different, which means this ratio deviated from the ideal value of 1:1. Based on the results of the analysis show that the value of X2 -count > X2 -table, then H0 is rejected, which means the sex ratio of male and female fish is not balanced from TKG I-VII for males and TKG II-VII for females and mostly found in TKG III conditions. The size of the male julung fish when the gonads first mature was estimated at a length of about 230-260 mm and the female at a size of 250-280 mm. The average Gonad Somatic Index (GSI) of female julung fish was 0.0876 and the standard error was 0.0061 with a GSI range of 0.0092 – 0.7574. The relation- ship between TKG and GSI shows that the increasing stage of fish gonad maturity will be followed by an increase in the value of the fish gonadal index.
