| 經費來源 | This monitoring was carried out within the framework of the Conservation and Sustainable Use of Natural Heritage / Bioeconomy program of the German Technical Cooperation - GIZ, jointly with the Ministry of Environment, Water and Ecological Transition. |
| 研究區域描述 | he El Pelado Marine Reserve (REMAPE) was created under Ministerial Agreement No. 118 on 24 August 2012, as stated in the publication of Official Gazette No. 802 of 03 October 2012. Subsequently, an extension of REMAPE was carried out, according to the Agreement Ministeriai No. 173 of June 20, 2014, which appears in the Official Enlargement Registry No. 300 of July 30, 2014 (Ministry of the Environment, 2014). This protected area includes an islet and an adjacent coastal marine zone, formed by rocky reef structures and coral patches that are habitat and refuge for a variety of of fish and invertebrates, among which are species of high commercial value for fish as well and dive tourism. All these organisms fulfill an important function in the marine environment and are indicators of the health of reef ecosystems. |
| 研究設計描述 | This monitoring is carried out under the monitoring protocol that has been designed in a simple and practical way, which allows the collection of continuous and long-term information, with the aim of evaluating the populations of octopus (Octopus spp) and identifying the changes in the populations. of these resources over time. On the other hand, monitoring is intended to be a tool for evaluating zoning and the management measures proposed within the Management Plan. he objectives that have been defined within this monitoring are the following: 1. Strengthening of capacities for the collection and analysis of biological and ecological information by the rangers of the MAATE and fishermen of the resource. 2. Generate information on the state of conservation of octopus populations (Octopus mimus), regarding sizes and abundance. 3. Disseminate useful information periodically, for making immediate, medium and long-term management decisions. |

取樣方法
The sampling was carried out at the coastal community of Ayangue, at the influence area of the El Pelado Marine Reserve. In this community there are a group of fishermen dedicated to fishing for octopus. The data collected were: total length, mantle length, weight and sex.
| 研究範圍 | Study Extent Long-term monitoring consists of studying organisms or environmental parameters over a long period of time to help us understand a variety of natural processes. A monitoring program can provide information on the diversity of the site, the condition of particular habitats, populations of species of organisms, and changes in the environment. In addition, it can facilitate the prediction of the effects of human activities on ecological processes. Without long-term data we cannot make appropriate decisions regarding the management of a natural system. This monitoring protocol has been designed in a simple and practical way, which allows the collection of continuous and long-term information, in order to evaluate the populations of octopus (Octopus spp.) and identify the changes in the populations of this resource. On the other hand, monitoring is intended to be a tool for evaluating zoning and the management measures proposed within the Management Plan of the Marine Reserve. |

方法步驟描述:
- S Step 1. - Total length (Total Length). – The length of the specimen will be considered with the help of an ichthyometer in centimeters, this measurement is taken from the end of the head to the end of the longest tentacle.
- Step 2. - Size of the specimen's mantle. To measure the length of the specimen's mantle will be considered the ranges from an imaginary line between the eyes to the upper end of the mantle (Hernández López, 2000), the measurement is also expressed in centimeters.
- Step 3. -Weight. It is taken in grams with a duly calibrated electronic scale.
- Step 4. Sex. -This data is important because you can know which is the predominant sex in the population. This information may help us to determine how well the population is. In order to distinguish the sex of octopuses (Octopus spp.), the most precise method is to study the gonads, but that means more manipulation and time that the fishermen will not hand very well, so we limit ourselves to observed "the hectocotyli, which is a sexual organ that performs the functions of a penis in male octopuses, located at the end of the third right tentacle of the animal that has reached maturity ”(Otero, 2006). On the other hand, the females have all arms at same size.
