... by Police (1932) as well as by us. Data on the Atlantic saury total catch in the Mediterranean Sea in the period (Deniz, Gökürk, & Ateş, 2016) showed significant peaks in 2008 and 2012. Unfortunately, data on fish stock availability, in particular on Atlantic saury landings, are not available for the study area, making it hard to attempt any correlations. ...
This study presents data on a local population of short‐beaked common dolphin monitored in the waters off Ischia Island (Gulf of Naples, Italy) over a 16‐year period (2000‐2015). We examine dolphin occurrence and distribution and perform photoidentification analysis. The data presented support the hypothesis that the waters around Ischia Island represent a feeding area, as well as a calving and an important nursery area for this local population, providing favourable conditions in which to give birth and raise calves. The levelling‐off of the photoidentification curves together with the continuous decline of the encounter rate lead us to believe that the area has been a hotspot for a local population (mainly resident) for years and that now this population is dying (has died) or is moving (has moved) to other locations. Several expanding human activities at sea have the potential to impact on the common dolphin in the study area, the most significant possibly being habitat disturbance and degradation (including traffic and noise pollution) and overexploitation of food resources by the fishery. The data presented in this study offer a strong argument for explicit and urgent population‐specific conservation and management strategies to be developed and applied locally for common dolphins, considering that they rely on the region for important biological processes.

Fisheries as an activity performed using natural resources are livelihood and strongly associated with the ecosystem. Hence it is a system which is characterized nesting complex relationship between society and the natural environment. Fisheries practices increased with the increase in the technological development and speed of globalization as well as environmental pollution. Therefore natural fish resources have been damaged for a long time. Most of fish stocks are fully fished and some are overfished. Focusing and monitoring on the sustainable use and conservation of renewable fish resources have a responsible manner for fisheries management. In simple terms, sustainable fisheries, known as harvested at a sustainable rate, means minimal ecosystem effects, healthy fish stocks and effective management. Turkey has an important spawning and fishing grounds for commercial fish species such as pelagic and demersal, so both large and small scale fishery are major economic activity. But yet it has been concerned that most of fish stocks are affected by overfishing and pollution in Turkey. For this purpose the aim of this study is to evaluate and improve the state of sustainable fisheries management in Turkey with the help of reported studies and official statistics regarding sustainable development for current and future practices.
