The Impact

This study presents the first fully corrected abundance estimates for the harbour porpoise (Phocoena phocoena) for Iceland and the Faroe Islands. In both regions reliable estimates are needed to assess the impact of by-catch and other threats to harbour porpoises. Aerial surveys with harbour porpoise as a secondary and main target species were conducted in the summers of 2007 and 2010 in Icelandic and in Faroese coastal waters respectively. In Iceland, the cue counting procedure was used (which also produces the data required for line transect analysis), while in the Faroese, standard line transect sampling was applied, following the SCANS-II (Small Cetacean Abundance in the North Sea) survey protocol. In both surveys, identical aircraft surveyed at an altitude of 600 ft and a speed of 90–100 kn. Only data collected during Beaufort Sea States (BSS) lower than 3 and during good or moderate porpoise sighting conditions were used for abundance estimates. Abundance estimates were corrected using stratified estimates of esw (incorporating g(0)) values derived during the SCANS-II survey in 2005 as principal observers took part in this survey as well. In Iceland, realised effort in good or moderate harbour porpoise sighting conditions totalled 8,289 km in 13 survey strata, where 77 sightings (109 individuals) were made by the experienced harbour porpoise observer only. In Faroese waters, only part of the area inside the 300 m depth curve could be surveyed and 1,564 km were surveyed in good or moderate porpoise sighting conditions, yielding 39 sightings (49 individuals). The total abundance estimates were 43,179 porpoises (CV=0.45; 95% CI: 31,755–161,899) for Icelandic coastal waters and 5,175 porpoises (CV=0.44; 95% CI: 3,457–17,637) for Faroese waters.

Seagrass communities play an important role in marine environments and estuary area, supporting communities of fish, snails and shellfish and other invertebrates. The diversity of seagrass species in the world is very low (<60 species). The coastal waters of Ori Village have a seagrass community that has never been studied. The purpose of this study was to estimate the structure of the seagrass community in the coastal waters of Ori Village, Central Maluku which includes the composition of type, density, frequency of occurence and percent of coverage. Seagrass sampling uses the line transect method. Five species of seagrass were found during the study grouped into two families: Cymodoceaceae and Hydrocharitaceae. The seagrass species found were Cymodocea rotundata, Halodule pinifolia, Enhalus acoroides Halophila ovalis and Thalassia hemprichii. T. hemprichii and E. acoroides have the highest densities (157 shoots/m2 and 137 shoots/m2, respectively). E. acoroides and T. hemprichii also have the highest frequency of occurence and relative coverage percent compared to other seagrass species found in the waters of Ori Village. Seagrass community in the waters of Ori Village is classified in a tight condition until dense.   ABSTRAK Komunitas lamun memegang peranan penting di lingkungan laut dan daerah estuari, menyokong komunitas ikan, siput dan kerang-kerangan serta invertebrata lainnya.

Abstract. Latupeirissa LN, Leiwakabessy F, Rumahlatu D. 2020. Species density and shell morphology of gold ring cowry (Monetaria annulus, Linnaeus, 1758) (Mollusca: Gastropoda: Cypraeidae) in the coastal waters of Ambon Island, Indonesia. Biodiversitas 21: 1391-1400. The purpose of this research was to examine environmental factors, species density, and the shell morphology of Monetaria annulus. The samples were collected by using the line transect method at 6 research stations. The data of the environmental factors (temperature, salinity, and pH of seawater) as well as species density of M. annulus were collected with in-situ technique, while the shell morphology of M. annulus was measured at Laboratory of the Deep-Sea Research Center, Indonesian Institute of Sciences (LIPI) Ambon. The results of the measurements of the environmental factors in the coastal waters of Ambon Island showed some fluctuations in the measurement values. The seawater temperature ranged between 29.78-30.05 ºC, the salinity of seawater ranged from 32.12-32.33‰, and the pH of the seawater ranged from 8.34-8.49. The density of M. annulus at the research stations from the highest to the lowest was at Tanjung Tiram station, Suli station, Seri station, Hutumuri station, Halong station, and Latuhalat station (0.27 > 0.24 > 0.23 > 0.19 > 0.14 > 0.12 ind/m2). The results of the measurement of the shell morphology showed many variations in the size and shape of the shell of M. annulus with a total number (N) of 294 individuals. The length, the width, and the height of the shell, the length of the blotches, the width of the blotches, and the total weight of M. annulus from each research station were significantly different (p<0.005). These results indicate that the differences in the shell morphology of M. annulus at each research station were influenced by waves, the strength of the currents sea waves, and the different substrate of water. In addition, the variation of shell morphology can be a reason for characterization in the taxonomy of the Cypraeidae family.

The Syngnathidae reef fish belongs to the vulnerable category of CITES due to the decrease in its original habitat. This is due to the high activity of predatory and utilization as raw material of traditional medicine. This study aims to study the ecological conditions including the distribution and abundance of reef fish Syngnathidae in the waters of the Blue Lagoon Karangasem waters and study the physical condition of its aquatic chemistry. This research was conducted from August to October 2017. The determination of research station was done based on Purposive sampling methods. For data retrieval of the Syngnathidae reef fish using square squares method with size 10x10 m in each sampling location. The result of this research is the emergence of species of reef fish Syngnathidae ranged from 1-4 individual at each location of observation. The results show that the ecological condition of the Syngnathidae reef fish in the Blue Lagoon coastal waters is of concern, this refers to the distribution and abundance of the limited reef fish Syngnathidae in its distribution. On the other hand, analysis of physical chemistry data shows that the condition of Blue Lagoon coastal waters tends to be stable. Measurement of water physics-chemical parameters obtained result of temperature measurement range 28-29oC, salinity 27-29 ppt, pH 7.08-7,89 and DO 7-7,75 mg/l. The result of physicochemical parameter measurement is related to the quality standard of Kep.Men.LH No.51 about the quality of the waters for marine biota was good for the existence of Syngnathidae reef fish. In general, the aquatic chemical physics conditions have a significant influence on the emergence of reef fish Syngnathidae found in stations 1 and III but not found in station II located in the middle of the waters between stations I and III.
