Global warming is affecting habitat quality and availability on our planet some species are predicted or by now changing their distribution range. Here we show that loggerhead turtles have already started to expand nesting range into the Western Mediterranean, which has until recently hosted only sporadic nests. We compiled information activity from beaches surrounding Mediterranean collected metadata turtle nests in Spain, France, Italy, Tunisia between 2010 2020 provide an exhaustive...
The Lessepsian migrant fish Lagocephalus sceleratus is being recorded for the first time from gulf of Gabes (Central Mediterranean, Tunisia). record based on a single specimen collected in December 2010. Previous records species were confined to Levantine and Aegean Seas. Recent research reveals that this extending its distribution area western Mediterranean. toxic, containing tetrodotoxin (TTX) paralyses nervous respiratory systems. Actions awareness taken Tunisia alert consumers fishermen...
longlines are a fishing gear that have traditionally been used world-wide.Surface mainly to fish swordfish, albacore, tuna and some species of sharks, while bottom large bottom-dwelling such as groupers.longlines widely known interact with several sea turtles, there is increasing concern about the impact by-catch on these species.however, paucity data turtle interactions longlines.In this paper we analyse interaction turtles both surface in zone Zarzis south gulf Gabès, which considered be...
Environmental policies, including the European Marine Strategy Framework Directive (MSFD), generally rely on measurement of indicators to assess good environmental status (GES) and ensure protection marine ecosystems. However, depending available scientific knowledge monitoring programs in place, quantitative GES assessments are not always feasible. This is specifically case for turtle species, which listed under Biodiversity Descriptor MSFD. Relying an expert consultation, goal this study...
Fisheries bycatch is considered one of the main threats to sea turtles. To provide an updated assessment impact on loggerhead turtles in Tunisia, 483 interviews were conducted with fishermen 19 ports along Gulfs Gabes and Hammamet. The interview questions included data vessel fishing gear characteristics, monthly effort, turtle last year. Results revealed that per unit effort (BPUE) was highest for ray nets (0.73 turtles/vessel/day, 95% CI [0.02-1.15]), followed by pelagic longlines (0.6...
Abstract Sea turtles may migrate vast distances from their feeding areas to home rookeries where they nest. During these migrations sea are subject many threats, among which interactions with pelagic longlines. This gear is used frequently in the summer period Gulf of Gabes targeting mainly sandbar shark ( Carcharhinus plumbeus ). Hooks baited mackerel Scomber scombrus ) or pieces stingray Dasyatis pastinaca Twenty‐one fishing trips (48 sets a total 35 950 hooks deployed) were conducted...
Ectothermic species are strongly affected by thermal changes. To assess the viability of these under climate change constraints, we need to quantify sensitivity their life history traits temperature. The loggerhead marine turtle (Caretta caretta) nests regularly in Oriental Basin Mediterranean Sea. different populations separated because time (< 12,000 yrs) and very habitats; it is hotter on southern coast (Libya) than northern ones (Cyprus, Greece, Turkey). Patterns embryo growth response...
This study explores the status of exploited shark populations in Gulf Gabes relation to fishing pressure, based on data pertaining longline fishery, collected during two periods. Catch from 48 and 96 pelagic sets collected, respectively, 2007/2008 2016/2017, were used compare species composition catch rates between Four recorded 2007/2008, while 11 additional demersal elasmobranchs along with teleosts fished 2016/2017. Elasmobranch dominated catches 94% 99.3% terms specimens number,...
This study investigates the prevalence, causes, and spatial distribution of Abandoned, Lost, or Discarded Fishing Gears (ALDFGs) in Gulf Gabès, a critical fishing area Tunisia. Five main gear types—benthic trawls, encircling nets, longlines, gillnets, trammel nets were analyzed for their loss rates contributing factors. The involved extensive surveys among local fishermen using geographic information system (GIS) tools mapping. findings reveal varying different types, with longlines...

Fishery bycatch poses a significant threat to sea turtles. This study provides an updated assessment of Loggerhead turtle (Caretta caretta) in the Gulf Gabès, focusing on impact Garrasia gillnets. Through 61 onboard observations conducted alongside fishermen Zarzis deploying bottom-set gillnet, called “Garrasia”, and targeting elasmobranch species, comprehensive data were collected, including number turtles captured, soak time, length gillnets, location, biometric Analysis revealed catch per...
ABSTRACT In the Mediterranean Sea, trawl nets and drifting longlines have been recognized as methods that capture thousands or tens of turtles. However, possible impact other fishing has not adequately addressed, especially for artisanal amateur fisheries use coastal nets. Coastal net fisheries, including driftnets set nets, used at a much shallower depth (<40 m) in Mediterranean, result large bycatch loggerhead turtles neritic zone. The mortality rate with these seems to be higher than...
A survey of cetaceans stranded along the Tunisian coastline (2004–2009) and a review literature allowed us to record total number 132 stranding events from 1937 2009. They included two species balaenopteridae, one physeteridae five delphinidae. The common bottlenose dolphin Tursiops truncatus (Montagu, 1821) fin whale Balaenoptera physalus (Linnaeus, 1758) were main in 83 21 cases, respectively, representing 78.78% all records. Stranding occurred year round, with highest frequency spring...
Hatchling sex ratios in the loggerhead turtle Caretta caretta were estimated by placing electronic temperature recorders seven nests at Kuriat islands (Tunisia) during 2013 nesting season. Based on mean temperatures middle third of incubation period, and duration, ratio hatchlings was highly male-biased. Presently, majority hatchling studies are focused major areas, whereby universally believed to be heavily female-biased. Here we present findings from a minor site Mediterranean, where found...
