Three decapod crustaceans (Penaeus notalis, Procambarus clarkii and Callinectes pallidus) were selected in this study due to their low cost and wide distribution across tropical and temperate regions of the world. The proximate, fatty acids, amino acids and total cholesterol contents of Penaeus notalis, Procambarus clarkii and Callinectes pallidus from Badagry Creek, Lagos, Nigeria were evaluated for their nutritional importance in diet and to human health especially as the demand for these resources is increasing worldwide due to increase in human population, low cost and nutritional benefits. The proximate composition of the selected crustaceans was determined using standard methods of analysis, the cholesterol content was determined using enzymatic kit method, the fatty acid composition was analysed using Gas Chromatography- Mass Spectrophotometer and the amino acid composition was analysed using Amino Acid Analyzer. The proximate composition (moisture, crude fat, crude fibre, crude protein, ash and carbohydrate contents) analysed showed significant difference (p<0.05) among the three selected crustaceans studied, so also the cholesterol content. All the fatty acids in the results obtained except (Palmitic acid (C16:0), magaric acid (C17:0), myristoleic acid (C14:1), (C18:1n-9t), (C22:1n-9), cetoleic acid (C22:1n11c), C18:2n-6t, rumenic acid (C18:2n-7), γ-Linolenic acid (GLA) (C18:3n-6), eicosatrienoic acid (ETE) (C20:3n-3), docosadienoic acid (C22:2n-6) and docosapentaenoic acid (DPA) (C22:5n-3)) showed significant difference (p<0.05). All the essential amino acids indicated significant difference (p<0.05). Moreover, all the non-essential amino acids except cystine were also significantly difference (p<0.05) among the three selected crustaceans. This study revealed that all the selected decapod crustaceans studied are good source of high quality protein, essential amino acids, low cholesterol levels, omega 3 and 6 polyunsaturated fatty acids thereby making them of high nutritional benefits to consumers.

This study aims to analyze the behavior of freshwater fish consumers in the Sabilulungan Modern Fish Market, Bandung Regency and to analyze the factors that encourage consumers to buy freshwater fish at PIM Sabilulungan. The method used in this research is a case study with research subjects, namely freshwater fish consumers at PIM Sabilulungan, using a rating scale analysis and rank spearman. The sampling technique used was accindental random sampling with a total of 40 respondents. The consumer purchasing decision process consists of five stages, namely the introduction of needs, information search, evaluation of alternatives, the purchase process and evaluation of post-purchase results. The results showed that at the introduction stage the need for motivation to purchase freshwater fish because fish have good nutrition, at the information search stage the source of information obtained by respondents was print / electronic media. In the alternative evaluation stage, the reason consumers buy freshwater fish at PIM Sabilulungan is because of the various types of fish. At the purchasing stage, respondents buy 1.1kg-3kg freshwater fish with a frequency of buying it twice a month. In the post-purchase evaluation stage, respondents are satisfied with the freshwater fish products being sold and the marketed prices are affordable. To see the factors that influence purchase motivation, the rank spearman test is used. The test results show that the product price and service quality are the factors that most influence the purchase decision of freshwater fish at the Sabilulungan Modern Fish Market with t count values ​​of 16.245 and 16.228.

Research related to coral reef cover and diversity on Tinabo Besar Island was carried out in 2018, so it is necessary to conduct further research to determine the cover and diversity of coral reefs on Tinabo Besar Island in a sustainable manner (Time series) in order to improve the quality of coral reef ecosystems in the waters and management of national park area. This research was conducted from 9 July 2019 to 7 August 2019 at Taka Bonerate National Park, Selayar Islands, South Sulawesi, Indonesia. Location of data collection on Tinabo Besar Island. The data taken includes coral reef cover with 4 stations representing the wind directions, namely north, south, east, and west. Coral reef data were collected using the LIT (Line Intercept Transact) method. Based on the research results, it was concluded that the percentage of coral reef cover on the island of Tinabo Besar, Taka Bonerate National Park, South Sulawesi ranged from 25.80% to 45.80%. The diversity is in the medium category with the index value (H') ranging from 1 - 3 based on the Shannon - Wienner Index. The average percentage of life corals from the four stations is moderately damaged.

As 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.
