CHAPTER III. EAFM Indicator Assessment Techniques on Fishing

     In evaluating EAFM indicators in the Fishing Technology domain, primary data obtained through direct field observations and secondary data from available references can be used. Interviews were conducted after determining the selected respondents from the sampling results. It was carried out by face-to-face debriefing utilizing a guide or questionnaire to obtain information according to the purpose of this study. The characteristics of direct interviews are as follows:

1. The interviewer and respondent do not know each other;

2. The interviewer asked the respondent to answer the following;

3. The interviewer is neutral, does not direct the respondent; and

4. The questions asked to follow the guide or questionnaire.

     Sampling was done using the stratified random sampling method, in which the interview respondents were determined in stages. This sampling technique pays attention to each population element from each group that does not overlap (homogeneous elements) and must have the same opportunity that can be taken. Strata sampling can use administrative limits or the type of fishing gear used. The allocation of the number of samples from each level is sought using the principle of proportional allocation.

     Data collection was carried out to obtain information on each indicator. Each indicator has criteria to determine its status; because each indicator has a different data source, the assessor needs to know where and how it can be obtained.

     In measuring the indicators of the Fishing Technology domain, the parameters measured are fishing gear, fishing methods, selectivity and capacity of fishing gear, API productivity, and placement of fishing gear with data collection techniques for each indicator described as follows:

Permissible fishing gear indicator data/information can be obtained through the following:

  • Direct observation of fishing areas and/or fishermen's homes to identify the type and selectivity of fishing gear used.

  • Report on the results of monitoring/supervision of capture fisheries from the relevant work unit.

  • Reports on the results of research/studies from research institutes and institutions.education university, or related academics; and/or

  • Results of interviews with other competent respondents

The steps for assigning a criterion value to the permitted API indicators are as follows:

  1. Data collection on all types of fishing gear used by fishermen in an inland waters ecosystem;

  2. Identification of types of fishing gear that are allowed, data on types of fishing gear that are prohibited, and fishing gear that have not been regulated in Permen-KP Number 18 of 2021;

  3. Count the number of fishing gear that is allowed, namely fishing gear that is prohibited and fishing gear that has not been regulated in Permen-KP Number 18 of 2021; And

  4. Give the criterion value (nk) of the indicators of the proper fishing gear with the following criteria values:

  • nk = 1, i.e., if there is the use of API that is prohibited or has not been legalized in applicable regulations, >5 types of fishing gear

  • nk = 2, i.e., if there is a use of API that is prohibited or has not been legalized in applicable provisions, 1-5 types of fishing gear

     EAFM analysis is a multi-attribute approach to symptoms or performance indications of aquatic ecosystem conditions in general. Substantially, the assessment of EAFM indicators is a system of multi-criteria analysis that culminates in a composite index assessment to determine the status of fisheries management using flag modeling (Adriantoet al., 2005). Data analysis is needed to find out the relationship between the current management performance status based on the data of each indicator in the Fishing Technology domain with recommendations for fisheries management actions that will be developed.

     Currently, tools can be used to analyze the condition of EAFM in general and the conditions of each EAFM domain, especially the Fishing Technology domain, using the EAFM indicator assessment matrix (as attached). In detail, the method of calculating the composite value on the indicators and domain of Fishing Technology is described as follows:

The formula used to calculate the composite indicator (CI) value of permitted fishing gear is:

CI2.1=br2.1nr2.1nk2.1

Description:

CI2.1 = composite indicators of permitted fishing gear

br2.1 = the weight value of the permissible fishing gear indicator

nr2.1 = ranking value of the permitted fishing gear indicator

nk2.1 = the value of the criteria for indicators of fishing gear that is allowed

Meanwhile, the formula used to calculate the weight value (br) of the fishing gear indicator is:

br2.1=(100 / (nr2.1+nr2.2+nr2.3+nr2.4 +nr2.5)) x  nr2.1image.png

The formula used to calculate the composite indicator value (CI) fishing methods are:

CI2.2=br2.2nr2.2nk2.2

Description:

CI2.2 =kcomposite fishing method indicators

br2.2 = the weight value of the fishing method indicator

nr2.2 = rank value of fishing method indicator

nk2.2 = criterion value of fishing method indicator

Meanwhile, the formula used to calculate the weight value (br) of the fishing method indicator is:

br2.2=(100 / (nr2.1+nr2.2+nr2.3+nr2.4 +nr2.5)) x  nr2.2image.png

The formula used to calculate the composite indicator value (CI) selectivity and the capacity of the fishing gear is:

CI2.3=br2.3nr2.3nk2.3

Description:

CI2.3 = indicator composite selectivity and fishing gear capacity

br2.3 = indicator weight value selectivity and fishing gear capacity

nr2.3 = indicator ranking value selectivity and fishing gear capacity

nk2.3 = indicator criterion value selectivity and fishing gear capacity

Meanwhile, the formula used to calculate the value of the br indicator selectivity and the capacity of the fishing gear is:

br2.3=(100 / (nr2.1+nr2.2+nr2.3+nr2.4 +nr2.5)) x  nr2.3

The formula used to calculate the composite indicator value (CI) API productivity is:

CI2.4=br2.4nr2.4nk2.4

Description:

CI2.4 = the composite indicator API productivity

br2.4 = the weight value of the API productivity indicator 

nr2.4 = the ranking value of API productivity indicators

nk2.4 = the value of API productivity indicator criteria 

Meanwhile, the formula used to calculate the value of the productivity indicator APIs is:

br2.4=(100 / (nr2.1+nr2.2+nr2.3 +nr2.4 +nr2.5)) x  nr2.4image.png

The formula used to calculate the composite indicator value (CI) of the placement of the fishing gear is:image.png

CI2.5=br2.5nr2.5nk2.5image.png

Description:

CI2.3 = composite indicator selectivity and fishing gear capacity

br2.3 = weight value indicator selectivity and fishing gear capacity

nr2.3 = ranking value indicator selectivity and fishing gear capacity

nk2.3 = criterion value indicator selectivity and fishing gear capacity

Meanwhile, the formula used to calculate the value of the br indicator placed in the fishing gear is:

br2.5=(100 / (nr2.1+nr2.2+nr2.3+nr2.4 +nr2.5)) x  nr2.5

      The Domain Composite Value (CD) for the Fishing Technology domain can be calculated by adding up all the CI values ​​obtained according to the following formula:

CD2=CI2.1+CI2.2+CI2.3+CI2.4+CI2.5image.png

Description:

CD2image.png = Value composite domain of Fishing Technology

CI2.1image.png = Value composite fishing gear indicator that allowed

CI2.2image.png = Value composite fishing method indicators

CI2.3image.png = value composite selectivity and fishing gear capacity indicator

CI2.4image.png = Value composite productivity of fishing gear indicator

CI2.5image.png = Value composite placement of fishing gear indicator

     The CD2image.png value obtained is used to analyze the flag status condition of the fishing technology domain within the framework of implementing fisheries management with an ecosystem approach or the Ecosystem Approach to Fisheries Management (EAFM) in inland waters. The status flag criteria for the fishing technology domain are grouped based on 3 (three) categories (Table 2).

The influence value of the Fishing Technology domain on the entire EAFM domain (CDI2)image.png can be determined by multiplying CD2 by the ranking weight for the Fishing Technology domain (brd2), according to the following formula:

CDI2=CD2 x brd2

Flags status of EAFM can be known by calculating the aggregate of all CDI values according to the following formula:

CA=CDI1+CDI2+CDI3+CDI4+CDI5+CDI6+CDI77

Description:

ca = Aggregated value of all EAFM domains

CDI1 = CDI value for the Fish Resources Environment domain

CDI2 = CDI value for Governance domain

CDI3 = CDI value for Social domain

CDI4 = CDI value for Governance domain

CDI5 = CDI value for the managed Fish Species domain

CDI6 = CDI value for Governance domain

CDI7 = CDI value for Stakeholder domainimage.png

The flag status criteria for fisheries management conditions in an inland waters ecosystem are grouped into 3 (three) categories (Table 4).

     In short, the assessment of the EAFM indicators for the case study in WPPNRI-PD 435 used in the process of input and analysis of the Fishing Technology Domain data can be illustrated as follows (Table 5):

Based on the calculation of the CD2 value above, it is known that the status flag for the Fishing Technology domain is red or deficient. It indicates that the condition of the local Fishing Technology domain has not yet implemented the principles of sustainable fisheries, so it is necessary to establish a strategic plan to improve or enhance the existing domain conditions and indicators.

Recommendations for fisheries management are formulated to determine strategic plans through policies/programs/activities addressing gaps, issues, and problems. Fisheries management recommendations are grouped based on the status flags of each EAFM domain. In general, recommendations for ecosystem-based fisheries management (Table 6).

         Meanwhile, recommendations can be applied to the Domain of Fishing Technology (Table 7).
