Surface sediments collected from 33 stations along the Ambarli Harbor, the Sea of Marmara, were analyzed for petroleum aromatic hydrocarbons by UV-fluorescence. Higher concentrations of total aromatic hydrocarbons were found of all the samples collected during May 2009, with levels ranging 1860 and 72 μg/g eq oil (205 and 7 μg/g chrysene eq.). The spectra indicate dominant pyrolytic origins in ...

Mauritania acquired the status of a lower-middle-income country in 2014. Economic development has relied primarily on fishing and mining. Fish is an important element achieving adequate nutrition these countries. But foodborne chemical microbial hazards that may be present fish are major concern. The purpose this study was to evaluate microbiological biochemical properties fresh sardines (Sardi...

Tropical rainforest regions are urbanizing rapidly, yet the role of emerging metropolises in driving wildlife overharvesting in forests and inland waters is unknown. We present evidence of a large defaunation shadow around a rainforest metropolis. Using interviews with 392 rural fishers, we show that fishing has severely depleted a large-bodied keystone fish species, tambaqui (Colossoma macropo...

The paper presents the synthesis and research of a new, more relevant detection model for Small Maritime Targets SMT such as yachts, sailing ships, fishing boats, cutters. For this purpose, effective reflection surfaces four types passive radar reflectors were identified in special laboratory anechoic chamber. A fluctuation small maritime target using Weibull probability distribution was formul...

Incidents of boats and fishing sinking in the waters Masalembu often occur. These accidents were caused by bad weather. Therefore, it is necessary to disseminate information on reducing impact meteorological threats community Masalembu. Activities implemented introducing that have been faced so far, ranging from rain accompanied strong winds, hurricanes, big waves lightning. Another activity he...

Fishing in the Mazarrón Bay has been practiced since prehistoric times. This was one of basic pillars area’s economy; however, due to development tourism, this maritime activity pushed into background. The changes fishermen’s way fishing last decades 20th century, as a consequence proliferation boats with greater extractive capacity, have meant that much gear fallen disuse. main objective resea...

As part of monitoring, control and surveillance marine fisheries, a logbook monitoring vessel system (VMS) were introduced for multi-day fishing. The present study investigates the possibility using VMS data to validate records fishing locations vessels. from 1,424 multiday vessels fitted with VMS, which was operated May 2017 April 2018. During period, there 17,626 trips 66,717 occasions. In tr...

Illegal, unreported, and unregulated (IUU) fishing has become a very profitable business, with nearly $23.5 billion worth of fish stolen from the world’s oceans. Every year business grows efficiently, Illegal is one big back steps in this business. Furthermore, many populations are pushed to extinction. This paper proposes illegal detection using data analytics machine learning techniques....
