Evaluation of rehabilitation is needed for planning a more sustainable program. This study aims to evaluate the implementation by formulating ecological parameters that affect coral reef and determine score weight success rate arrange strategi managing rehabilitation. In this research used descriptive method, with determination key evaluation scores, based on literature study. Determination usi...

Although spearfishing is a popular method of capturing fish, its ecological effects on fish populations are poorly understood, which makes it difficult to assess the legitimacy and desirability of spearfishing in multi-use marine reserves. Recent management changes within the Great Barrier Reef Marine Park (GBRMP) fortuitously created a unique scenario by which to quantify the effects of spearf...

Our definition of the word 'animal' centers on vertebrates, yet 99% of the animals on the planet are invertebrates, about which we know little. In addition, although the Census of Marine Life (COML.org) has recently conducted an extensive audit of marine ecosystems, we still do not understand much about the animals of the seas. Surveys of the best-known ecosystems, in which invertebrate populat...

The recent miniaturization of acoustic tracking devices has allowed fishery managers and scientists to collect spatial and temporal data for sustainable fishery management. The spatial and temporal dimensions of fish behavior (movement and/or vertical migrations) are particularly relevant for rockfishes (Sebastes spp.) because most rockfish species are long-lived and have high site fidelity, in...

Government-managed marine protected areas (MPAs) can restore small fish stocks, but have been heavily criticized for excluding resource users and creating conflicts. A promising but less studied alternative are community-managed MPAs, where resource users are more involved in MPA design, implementation and enforcement. Here we evaluated effects of government- and community-managed MPAs on the d...

This paper investigates the ecological-economic sustainability of coral reef socio-ecological systems under fishing and environmental pressures. To achieve this, a dynamic, spatially explicit, multi-species, multi-fleet fisheries model is developed. Stochastic shocks are assumed to alter cover consequently entire social-ecological system. The calibrated using ecological, socio-economic data in ...

Abstract Modern coral reefs face substantial threats that endanger their capacity to function and provide resources for human populations. Chronic pressure through exploitation land-based pollution has led reef degradation lower productivity. More recently, this is compounded with successive episodes of bleaching across the tropical oceans. However, response trajectories exploitation, habitat d...

Exploitation impacts and management options for 15 coral reef fish species central to the commercial recreational fisheries of southern Florida USA ecosystem were evaluated using a length-based risk analysis (LBRA) framework. Population abundance-at-length composition data obtained from several regional federal-state sampling programs. These updated life history demographic integrated into nume...

OR RE CT ED P Abstract The Pacific shrimp fishery is the most economically important and ecologically impactful fishery in Mexico. Strong export markets have had a tremendous influence on the technological development and structure of this fishery. This article describes the historical development, current status, ecological impacts and management of the open ocean trawling component of the shr...
