Since January 2014, the reformed Common Fisheries Policy (CFP) of European Union is legally binding for all Member States. It prescribes end overfishing and rebuilding stocks above levels that can produce maximum sustainable yields (MSY). This study examines current status, exploitation pattern, required time rebuilding, future catch, profitability 397 stocks. Fishing pressure biomass were estimated from 2000 to last year with available data in 10 ecoregions 2 wide ranging regions. In data,...
Abstract This study presents a new method (LBB) for the analysis of length frequency data from commercial catches. LBB works species that grow throughout their lives, such as most commercially-important fish and invertebrates, requires no input in addition to data. It estimates asymptotic length, at first capture, relative natural mortality, fishing mortality. Standard fisheries equations can then be used approximate current exploited biomass unexploited biomass. In addition, these...
Scientific information on the biodiversity of marine caves in eastern Mediterranean is limited, especially when considering extensively studied north-western and central Mediterranean. Aiming to enhance current knowledge regarding cave communities, this study represents a first assessment biota Mediterranean, as has been defined by European Union’s Marine Strategy Framework Directive (MSFD). Information retrieved from an extensive overview relevant scientific documents was combined with...
Abstract The Law of the Sea and regional national laws agreements require exploited populations or stocks to be managed so that they can produce maximum sustainable yields. However, exploitation level stock status are unknown for most because data required full assessments missing. This study presents a new method [abundance yields (AMSY)] estimates relative population size when no catch available using time series catch-per-unit-effort other abundance indices as main input. AMSY predictions...
Eutrophication is one of the most important anthropogenic pressures impacting coastal seas. In Europe, several legislations and management measures have been implemented to halt nutrient overloading in marine ecosystems. This study evaluates impact freshwater control on higher trophic levels (HTL) European ecosystems following descriptors criteria as defined by Marine Strategy Framework Directive (MSFD). We used a novel pan-European modeling ensemble fourteen HTL models, covering almost all...
Following an introduction to the nature of fisheries catches and their information content, a new development CMSY, data-limited stock assessment method for fishes invertebrates, is presented. This version, CMSY++, overcomes several deficiencies which itself improved upon “Catch-MSY” published by S. Martell R. Froese in 2013. The catch-only application CMSY++ uses Bayesian implementation modified Schaefer model, also allows fitting abundance indices should such be available. In absence...
Understanding the resilience of temperate reefs to climate change requires exploring recovery capacity their habitat-forming species from recurrent marine heatwaves (MHWs). Here, we show that, in a Mediterranean highly enforced protected area established more than 40 years ago, octocoral populations that were first affected by severe MHW 2003 have not recovered after 15 years. Contrarily, they followed collapse trajectories brought them brink local ecological extinction. Since 2003, impacted...
There is a recognized need for new methods with modest data requirements to provide preliminary estimates of stock status data-limited stocks (e.g. Rudd and Thorson, 2018). Froese et al. (2018) such method, which derives relative size from length frequency (LF) exploited stocks. They show that their length-based Bayesian biomass estimation method (LBB) can reproduce the “true” parameters used in simulated approximate as estimated independently by more data-demanding 34 real...
Stocks with low market value are rarely included in stock assessments because their catch records generally lacking, thus adding to the already large number of un-assessed fisheries at a global scale. T his deficiency is more evident Mediterranean Sea where relatively fewer. A new method (AMSY) has been recently developed assess stocks for which only abundance trends from scientific surveys available. The AMSY was used Aegean status 74 fish and invertebrate (50 actinopterygians, 4 sharks, 5...
We estimated the current level of knowledge concerning several biological characteristics Mediterranean marine fishes by carrying out a gap analysis based on information extracted from literature, aiming to identify research trends and future needs in field fish biology that can be used stock assessments, ecosystem modeling fisheries management. Based datasets emerged literature review, there is no any characteristic for 43% (n = 310) species, whereas an additional 15% 109) them about just...
Abstract The multi-level benefits that marine organisms gain when protected from fishing are well acknowledged. Here, we investigated the effects of a 40-year trawling ban on status targeted and non-targeted species within major ground in northeastern Mediterranean Sea (Thermaikos Gulf, Aegean Sea). Biomass somatic length fish invertebrates (six commercial three non-commercial demersal species) were measured areas varying pressure, depending temporal spatial operational regimes vessels....
This review evaluates the current knowledge of essential biological traits (diet, fecundity, maturity, length-weight relationships, spawning, growth, lifespan, and natural mortality) marine fishes across European adjacent waters. These are crucial for ecosystem modeling stock assessments. Using data from FishBase, largest most comprehensive database on fishes, a gap analysis was performed to identify areas research focus corresponding gaps that require further study. Biological coverage is...
An up-to-date systematic review and unofficial codification of the national fisheries legislation was performed, along with an environmental, archaeological maritime legislation, about spatio-temporal restrictions fishing activities by all gears in Aegean Sea. Spatio-temporal established European Union General Fisheries Commission for Mediterranean were also reviewed. A database built, including detailed information on Restricted Areas (FRAs) being identified. All FRAs mapped, as polygons...
Ecosystem models can be used as fisheries management tools in the context of a holistic approach and view assessing status aquatic ecosystems proposing plans action. The Ecopath with Ecosim modelling suite has been widely to describe exploited marine systems perform simulations over time. Pagasitikos Gulf is shallow semi-enclosed gulf western coast central Aegean Sea that characterized semi-protected, bottom trawling ban force since 1966. In this study, an model was constructed including 31...
The Mediterranean Sea is a renowned biodiversity hotspot influenced by multiple interacting ecological and human forces. A gap analysis on the biology of marine fishes was conducted in 2017, revealing most studied species biological characteristics, as well identifying knowledge gaps areas potential future research. Here, we updated this five years later reviewing literature containing information same eight namely length-weight relationships, growth, maximum age, mortality, spawning,...
