Factors Influencing the Lipid Content and Fatty Acids Composition of Freshwater Fish: A Review
No full textFish farming has a long tradition in Central Europe. Aquaculture is highly developed here and even so, freshwater fish meat consumption is still very low. Freshwater fish meat is an important source of n–3 long-chain polyunsaturated fatty acids (PUFA), principally eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) which have an indisputable effect on human health and prevent the genesis of human coronary disease. Previous researches revealed many aspects affecting the PUFA quantity. In general, the fatty acid composition of fish lipids affects age, seasonal change, nutrition, sex, reproductive cycle, geographical location, etc. This review represents a step towards the characterization of the fatty acid composition of economically important freshwater fish species from different points of view, including the above-mentioned factors and taking into consideration the way of stunning and differences of lipid composition in individual fish body sections

No full textMorotai has abundant marine biological resources, sharks being one of them. The blacktip reef shark is one of the dominant types of coral reef sharks in Morotai waters. Worldwide shark are threatened due to the demand for shark fins and over fishing, to protect sharks is important to know their distribution so protected areas can be established. This research aims to examine the distribution of blacktip reef sharks (Carcharhinus melanopterus) based on habitat characteristics in the Morotai Waters. Through surveys and observation of coral cover, using the Line Intercept Transect (PIT) method and the Baited Remote Underwater Video (BRUV) to record the blacktip reef sharks who passed by the coral reef. Water quality parameters measured include temperature, salinity, visibility, acidity, current type, tides, and moon phases. Blacktip reef sharks were found in three of the four research stations. Station 4 was the one with the most blacktip reef shark appearances, amounting to 91 individuals. This station has the lowest sloping contour and has the smallest live coral cover of only 1%. Station 4 is dominated by sand covering 40%. All water quality parameters influence blacktip reef shark occurrence. The highest appearance of the blacktip reef shark happens during the new moon phase, when the tides are loose and the currents are quite strong
Mangrove Ecosystem Connectivity Based on Oceanographic System in Biawak Island, West Java, Indonesia
No full textThis research aims to determine the ecosystems connectivity by observing the distribution of inter-island mangrove propagules in the territorial waters of Biawak Island. The data used are wind, tidal, and bathymetry of 2018. They are modeled according to the propagules’ weight and the particle trajectory module. The results showed that the entire propagules (Rhizopora sp, Sonneratia sp, and Brugueira sp) dominantly moved to the west and southeast. They are carried by the currents that are influenced by the west and east monsoon. The propagules of Rhizopora sp moves from east to southeast, Sonneratia sp moves from east to south, and propagules Brugueira sp moves from west to north. In addition to oceanographic factors, other parameters that can influence the pattern of propagules movement is the propagule’s mass; the lighter it is, the easier it is to be carried away
