Abstract
Antagonistic interaction between Mediterranean marine mammals, including the endangered monk seal (Monachus monachus), and small-scale fisheries is a growing problem in the Aegean Sea. Effective management measures are needed to ensure both the survival of the monk seal population, and its coexistence with the small-scale fisheries. In this study, data from 371 fishing journeys by 8 different boats was collected between March and November 2014. Evidence of depredation by monk seals was recorded in 19.1% of fishing journeys, by cetaceans in 5%, and by other predators in 16.5%. Analysis of landings data showed that gear and depth were the variables most likely to influence the occurrence of depredation. There was a significant decrease in the catch per unit effort (CPUE) of four of the nine targeted fish species when depredation by monk seals occurred. The total cost of monk seal depredation was estimated to be 21.33% of the mean annual income of fishermen in the Aegean Sea. We discuss how the implementation of marine protected areas and the use of specific fishing gear could reduce the frequency of interactions, and thus mitigate the loss experienced by the fisheries as well as contribute to the conservation of an endangered species.

The existing regulation on disturbance of Mediterranean monk seals in caves along the Turkish coast was amended exactly as proposed by SAD-AFAG in January this year and published by the DG Fisheries & Aqua Products in the Official Gazette on 13 August 2016. The amended regulation reads as follows: “It is forbidden to use any light source inside, dive by any means into, enter by swimming or any other way into, wait or anchor in front of either underwater or surface entrances to caves used by Mediterranean monk seals”. The amended version of the related article was published in both, the Professional Aqua Product Fishery Circular No 2016/35 and the Recreational Aqua Products Fishery Circular No 2016/36.

Recent sightings of the Mediterranean monk seal Monachus monachus and evaluation of anthropogenic activities with recommended conservation implications in Antalya Bay, Turkey

Introduction
Mediterranean monk seals (Hermann, 1779) were once widely and continuously distributed in the Mediterranean Sea, Black Sea and North Atlantic waters (Aguilar 1999). The species is considered to be one of the world’s most endangered pinnipeds, with the global population estimated to be around 500 individuals (Karamanlidis & Dendrinos 2015), only 50-100 of which are left in Turkey (Güçlüsoy et al. 2004; Öztürk et al. 1991). Antalya Bay is subjected to high marine traffic year-round, and especially during summer months, when tourism activities peak. We report the most recent sightings of Mediterranean monk seals in Antalya Bay and investigate the impact of boat traffic on the species. Considering that the population in the Turkish Mediterranean is estimated at around 40 individuals (Güçlüsoy et al., 2004), the recent sightings in Antalya are of vital importance for the knowledge of the overall Turkish population, and provide great insight for conservation plans and consequently for the species’ survival in the region.

Translocation déjà vu

COMMENT

CBD_Habitat_screenIn declaring the Mediterranean monk seal colony at Cap Blanc in Mauritania/western Sahara “closed” [see blog], is Spanish NGO CBD-Habitat edging ever closer to resurrecting a plan that would see seals artificially translocated to other areas? The theory is that this would minimise the risk to the colony posed by mass mortality events, while helping to recolonise areas historically occupied by the species. Unfortunately, as earlier abandoned attempts to translocate or captive breed monk seals proved, the devil is in the detail. Continue reading “Translocation déjà vu”

Tourists “smother” tame Mediterranean monk seal ‘Argiro’ with their caresses — Report

FokiaArgyroTouristesAs long predicted by TMG, tourists swimming with and petting the tame, human-imprinted Mediterranean monk seal named ‘Argiro’ on the Eastern Aegean  island of Samos are at serious risk of bites, scratches and even more serious injury. While their compassion for the seal may be a plus point for the conservation of the species, the numbers flocking to pet and swim with her are exacerbating Argiro’s human imprinting and putting the welfare of both seal and bathers in jeopardy.

MOm reports on the progress of Andriana

from MOm’s Facebook page

A month after her release, Andriana continues to enjoy her journeys in the northwestern Aegean. The daily distances she travels are impressive, while diving depth has been steadily increasing and has reached to a depth of 50m. Until now Andriana has completed her first “tour” of the northwestern Aegean Sea (as can be seen on the map), returning just recently to the island of Alonissos in the National Marine Park of Alonissos, Northern Sporades (NMPANS). During this “tour” Andriana managed already to get entangled in a long-line; we would like to thank our friend from Kria Vrisi at the island of Evoia and the members of the Management Body of the NMPANS who helped to free Andriana from this fishing equipment.

Every single one of us can make a difference and help, not only Andriana, but all wildlife live in harmony next to us. It should be noted that the data collected by Andriana’s tag are extremely important in helping us understand how monk seals move and behave in their marine environment and ultimately help us protect them more efficiently.
