“…For instance, they caught large amounts of B. boops, which was a target species for them, but also caught S. cabrilla, which was not a target species but contributed to their income. Species availability seems, therefore, to determine the strategy employed by fishermen, as it was also previously reported in other areas [16,51,52]. As a result, the fishermen adjust their strategies based on the market demand, so as to make profit.…”

Small-scale fisheries constitute an important component of coastal human societies. The present study describes the small-scale net fisheries on Kalymnos Island (south-east Aegean Sea) that harbors the largest small-scale fleet in the eastern Mediterranean Sea. In addition, this study aims to evaluate their characteristics and economics. Relevant métiers were identified through a multivariate analysis by inputting the main resources and fishing gear data that were recorded during landings. Four main practices were observed being used as fishing gears, gillnets and trammel nets, targeting the species Mullus barbatus, Boops boops, Mullus surmuletus, Scorpaena porcus, and Sepia officinalis. Further analysis, which incorporated data concerning the type of the gear used, revealed 11 distinct métiers. Most of these métiers are practiced by other Mediterranean small-scale fisheries as well, in terms of target species, gear and seasonality. However, the métier that had its target species as B.boops is not practiced in other Mediterranean small-scale fisheries. The seasonal rotation of métiers was determined by the availability of different species rather than their market price. The results revealed the difference in fishing practice used by the fishermen in the study area compared to other fishing practices in the Mediterranean Sea. In particular, the fishermen of this study area targeted more species (B.boops) with a very low market price. They also provided essential information for the development and implementation of management plans aiming at the sustainability of small-scale fisheries.

“…Berdasarkan hasil wawancara, jenis multigear yang digunakan oleh nelayan sebagian besar bertujuan untuk meningkatkan hasil tangkapan karena target spesiesnya menjadi lebih banyak. Saldana et al (2017) menjelaskan bahwa tidak hanya faktor ekonomi dan ketrampilan yang menentukan perubahan target spesies, namun juga ketersediaan spesies tersebut di wilayah pe-…”

ABSTRACT Multigear has been commonly used in small-scale fishery activities in Sungsang waters. The aim of using the multigear is to enable the fishermen carry out their activities at every catching season. Inaccurate and inefficient use of the multigears are the concern that will present inefficiency or even conflict among the fishermen. Therefore the research was carried out with the objective to determine the best type of a multigear that will be used in the small scale fishery at Sungsang waters based on economic, productivity, social and biological aspects. Multiple Criteria Analysis (MCA) is the method of assessment on the quality type of the multigear. The outcome of the research presented that the best quality type of the multigear is 1) the multigear type with the combination of trammel net and drift longline; 2) the multigear type with the combination of drift gillnet (mesh, 3 inches) and drift long line; 3) the multigear type with the combination of drift gillnet (mesh, 2 inches) and trammel nets. Key Words: MA analysis, small-scale fishery, the best quality multigear,ABSTRAKMultigear telah banyak digunakan pada usaha perikanan tangkap skala kecil di Perairan Sungsang. Tujuan penggunaan multigear adalah dikarenakan agar nelayan dapat terus melakukan aktivitas penangkapan dalam setiap setiap musim penangkapan. Penggunaan multigear yang tidak tepat dan bijak, dikhawatirnya malah akan menimbulkan inefisiensi atau bahkan menimbulkan konflik antar nelayan. Oleh kerana itu, penelitian ini dilakukan dengan tujuan untuk menentukan jenis multigear unggulan pada usaha perikanan tangkap skala kecil di Perairan Sungsang berdasarkan aspek ekonomi, aspek produktivitas, aspek sosial, dan aspek biologi. Penilaian keunggulan jenis multigear menggunakan metoda Multiple Criteria Analysis (MCA). Hasil penelitian menunjukkan bahwa jenis multigear unggulan adalah: 1) jenis multigear dangan kombinasi jaring udang dan rawai hanyut; 2) jenis multigear dangan kombinasi jaring insang hanyut (mesh, 3 inci) dengan rawai hanyut (umpan), dan 3) jenis multigear dengan kombinasi jaring insang hanyut (mesh, 2 inci) dan jaring udang. Kata kunci: MCA analysis, perikanan skala kecil, multigear unggulan

“…The former includes monitoring programs within the areas of distribution of resources, which are generally costlier than the latter (Maunder & Punt, 2004; Damalas, Megalofonou & Apostolopoulou, 2007; Chuenpagdee, 2011; Reyes, Ramirez & Schuhbauer, 2013; Szuwalski et al, 2016; Gibson-Reinemer et al, 2017). The use of fisheries-dependent data has been the most common approach employed for stock assessment and fisheries evaluation, especially in developing countries (Salas et al, 2007; Cardinale et al, 2014; Saldaña et al, 2017).…”

“…Several factors have strong implications for the assumption of proportionality between CPUE and stock abundance, including changes in resource distribution, fishing gear (Arreguín-Sánchez, 1996; Gibson-Reinemer et al, 2017), boat characteristics, time of the day when fishing operations are performed, changes in environmental conditions (Maunder & Punt, 2004), as well as those associated with fisher’s behavior patterns (Salas, Sumaila & Pitcher, 2004; Naranjo-Madrigal, Van Putten & Norman-López, 2015). Identification of some of these factors can provide insights on how to improve monitoring and assessment programs where limited capacity (budget or personal) exists (Maunder & Punt, 2004; Salas & Gaertner, 2004; Saldaña et al., 2017). One way to deal with variability of catch rates has been through the standardization of the CPUE, using Generalized Linear Models (GLM) and Generalized Additive Models (GAM) (Denis, Lejeune & Robin, 2002; Maunder & Starr, 2003; Maunder & Punt, 2004; Yu, Jiao & Carstensen, 2013; Campbell, 2015; Walsh & Brodziak, 2015; Montero et al, 2016).…”

Management of low-mobility or benthic fisheries is a difficult task because variation in the spatial distribution and population dynamics of the resources make the monitoring and assessment of these fisheries challenging. We assumed that environmental, spatial, and temporal factors can contribute to the variability of the relative abundance of such species; we used Generalized Additive Models for Location Scale and Shape (GAMLSS) to test this hypothesis using as a case study the lobster fishery (targeting two species) in the Galapagos Marine Reserve, Ecuador. We gathered data on each of the two species of lobster on a monthly basis over seven years, including: (a) onboard observers’ records of catch data, fishing effort, and ground location by trip, and (b) data from interviews undertaken with fishers at their arrival to port, recording the same type of information as obtained from onboard observers. We use this information to analyze the effect of the measured variables and to standardize the Catch per Unit Effort (CPUE) in each case, using the GAMLSS. For both species, the temperature, region, fishing schedule, month, distance, and the monitoring system were significant variables of the selected models associated with the variability of the catch rate. For Panulirus penicillatus, CPUE was higher at night than during the day, and for Panulirus gracilis it was higher during the day. Increased temperature resulted in a decrease of CPUE values. It was evident that temporal, spatial scales and monitoring system can influence the variability of this indicator. We contend that the identification of drivers of change of relative abundance in low-mobility species can help to support the development of monitoring and assessment programs for this type of fisheries.
