Biodiversity in the Black Sea - ecological Study from the Perspective of Romanian philately
No full textAs the concern for the management of protected areas is relatively new in Romania, and the information related to this topic is relatively scarce, especially those on marine ecosystems, we considered necessary this study on the management of marine protected areas with specific biodiversity illustrated by philately. Marine protected areas, in particular, delimited as areas where the main purpose is the protection of nature and cultural values, are important for all segments of society. Through this paper, we aimed to review several aspects, ecological and philatelic alike, regarding the specific biodiversity of the Black Sea ecosystem. Following the analyzes performed on account of the data from the consulted specialized literature (in the form of postage stamps, FDCs, occasional envelopes, and maximum postcards, but also other philatelic effects), as well as as a result of other observations (with catalogs and sites with philatelic content), we concluded that the biodiversity of the Black Sea, as well as the marine ecosystem itself, are relatively well represented in Romanian philately. The four philatelic issues illustrate crustaceans, mollusks, corals, and anemones, but also other species, all being to the liking of the general public in terms of information and promotion

Selectivity of Gillnet to Catch Silver Pomfret (Pampus argenteus) in Pangandaran Waters, Indonesia
No full textThe purpose of this research was to determine the most selective mesh size of gillnet fishing gear for Pampus argenteus in coastal waters of Pangandaran Regency, West Java. Research on the selectivity of gillnet fishing gear was carried out in the coastal waters of Pangandaran, West Java Province, from August 2018 to January 2019. The method used in this research is experimental fishing, namely operating gillnet fishing gear directly in the fishing area with fishermen. The primary data collected was the measurement of the catch (fish weight, number, fork length, how the fish was caught, circumference (girth opercullum, maximum body girth). Meanwhile, the secondary data collected were supporting data from the Pangandaran District Fisheries and Marine Service, and literature study. In determining the sampling, the method used is the purposive sampling method. The operation of gillnets using 4.5 inches obtained a higher proportion of main catch (75%) than gillnets with a mesh size of 5 inches (44%). Gillnet with a mesh size of 4.5 inches, the silver pomfret caught was distributed between 17-22 cm in size with the highest mode in the 19 cm fork length. Unlike the gillnet fishing gear with a mesh size of 5 inches, the silver pomfret caught was distributed in the fork length range of 17-25 cm with the highest mode in the length class 19 cm fork length. mesh size 4.5 inches has a hanging ratio value of 0.51. Meanwhile, the 5 inch mesh size has a hanging ratio value of 0.54. Based on the length distribution, gillnets with a mesh size of 5 inches were more dominant in catching silver pomfret in a larger size class interval than gillnets with a mesh size of 4,5 inches. Based on the L50 value, both selective gillnets caught more fish at 50% second chance. The selectivity curve shows that gillnet fishing gear with a mesh size of 5 inches has more selective results than gillnets with a mesh size of 4.5 inches.

Relationship of Temperature and Chlorophyll-a with Distribution of Yellowstripe Scad (Selaroides leptolepis) in East Coastal Waters of North Sumatra
No full textThe east coast of North Sumatra is part of the Malacca Strait, a highly utilized fishing area. One of the commodities that can be harvested is the Yellowstripe Scad (Selaroides leptolepis). Through oceanography parameters, specifically temperature and chlorophyll-aconcentrations, it is possible to determine optimal fishing grounds which can be used as guidelines. One of the satellites that can detect sea surface temperature (SST) and chlorophyll-a concentrations is Aqua (EOS PM),which is equipped with a Moderate Resolution Imaging Spectroradiometer (MODIS) sensor. Data on the Yellowstripe Scad (Selaroide sleptolepis) were obtained from the Belawan Ocean Fishing Port (OFP). Based on the analysis of MODIS images from the Aqua satellite, the sea surface temperature of theeast coastal waters of North Sumatra in 2012 - 2016 ranged from 29oC – 32oC with chlorophyll-a concentrations ranging from 0.19 - 5.26 mg/m³. The largest harvest occurred during the west monsoon with a value of 143.46 tons and the lowest was during the east monsoon with a value of 139.87 tons. Yellowstripe Scad harvest has a negative correlation with the sea surface temperature with a correlation value of -0.365. Chlorophyll-a concentrations and harvest amount have a positive correlation value of 0.660. Yellowstripe Scad is predicted to yield the largest harvest during the west monsoon (December-February) between the Asahan and Labuhanbatu Regencies at coordinates 2.68oN - 2.74oN and 100.37oE - 100.44oE
