Spatial Management

Marine conservation areas are an important tool for the sustainable management of multispecies, small-scale fisheries. Effective spatial management requires a proper understanding of the spatial distribution of target species and the identification of its environmental drivers. Small-scale fisheries, however, often face scarcity and low-quality of data. In these situations, approaches for the prioritization of conservation areas need to deal with scattered, biased, and short-term information and ideally should quantify data- and model-specific uncertainties for a better understanding of the risks related to management interventions. We used a Bayesian hierarchical species distribution modeling approach on annual landing data of the heavily exploited, small-scale, and data-poor fishery of Chwaka Bay (Zanzibar) in the Western Indian Ocean to understand the distribution of the key target species and identify potential areas for conservation. Few commonalities were found in the set of important habitat and environmental drivers among species, but temperature, depth, and seagrass cover affected the spatial distribution of three of the six analyzed species. A comparison of our results with information from ecological studies suggests that our approach predicts the distribution of the analyzed species reasonably well. Furthermore, the two main common areas of high relative abundance identified in our study have been previously suggested by the local fisher as important areas for spatial conservation. By using short-term, catch per unit of effort data in a Bayesian hierarchical framework, we quantify the associated uncertainties while accounting for spatial dependencies. More importantly, the use of accessible and interpretable tools, such as the here created spatial maps, can frame a better understanding of spatio-temporal management for local fishers. Our approach, thus, supports the operability of spatial management in small-scale fisheries suffering from a general lack of long-term fisheries information and fisheries independent data.

Abstract Growing seal populations are examples of successful marine management, and the seals are often seen as a symbol of a thriving ecosystem. However, seals are well known to interact with local small-scale fisheries by feeding from the gears. This causes both lost catches and broken gear, which negatively affect the economic viability of the small-scale fisheries. While lost catches are known to be substantial, no information is currently available on costs for mending gear, searching for fishing grounds with less seals, etc. This article estimates these costs from a questionnaire sent to Swedish fishers. The total cost due to seals for small-scale fisheries is about €690 000, which corresponds to 7% of the expenditure for purchased goods (not labour and capital). The total time spent on seal-related work corresponds to ∼8% of total working time. Combining additional costs with revenue losses due to decreased catches, it is shown that the economic viability of the small-scale fisheries becomes low due to the seal interaction, which affects the economic and social sustainability of the sector.

Kesenjangan gender atau perbedaan peran laki-laki dan perempuan terhadap akses dan kontrol dalam pengambilan keputusan pada aktivitas perikanan skala kecil di Kabupaten Natuna masih tinggi. Penelitian ini bertujuan untuk menganalisis kesenjangan gender pada pemanfaatan perikanan skala kecil di Kabupaten Natuna; dan merumuskan strategi untuk mencapai kesetaraan gender. Data yang digunakan adalah data primer yang terpilah gender. Data primer dikumpulkan pada bulan Agustus 2019 terhadap 52 responden nelayan penangkap ikan skala kecil di 5 (lima) kecamatan di Pulau Bunguran – Kabupaten Natuna. Data diolah dan dianalisis dengan menggunakan software excel untuk memperoleh persentase tiga keputusan responden pada 5 kecamatan tersebut. Hasil analisis menunjukkan pengambilan keputusan pada perikanan skala kecil di Kabupaten Natuna masih didominasi oleh laki-laki. Kesenjangan gender terjadi pada aktivitas persiapan penangkapan ikan, kegiatan penangkapan ikan di laut, paska panen (penangkapan) ikan. Oleh karena itu, Pemerintah Daerah Kabupaten Natuna perlu merancang program stimulasi ekonomi untuk membuka lapangan kerja bagi perempuan dan memberi peluang partisipasi terhadap istri nelayan dalam pengambilan keputusan, dengan melibatkannya dalam kegiatan pelelangan ikan di tempat pelelangan ikan (TPI) atau pengurus armada penangkapan ikan. Title: Gender Gap of Small Scale Fisheries Utilization in Natuna Regency The gender gap or the different role of access and control among men and women on the decision making process in small scale fishery activities in Natuna is remain high. The purpose of this research is to analyze the gender gap in small-scale fisheries utilization and to provide the strategy to achieve gender equality. Gender disaggregated primary data were collected in August 2019 from 52 respondents of the small scale fishermen in 5 sub regency in the Bungguran Island of Natuna Regency. The data were processed using excel software to find out the percentage of 3 reasons for respondent participation. The findings shows that decision maker is dominated by fishermen. The gender gap occurred in preparation process of the fishing activities, fishing activities, and post fishing activities. Therefore, government of Natuna Regency must prepare the economic stimulus program for providing labor opportunities for women, encourage the participation of the fishermen’s wife in decision making process by involving them in fish auction activity or as manager of fishing fleets.

The incidence of the Covid-19 pandemic indirectly affects the decline in the activity of the processing industry and fish consumption by the community. In the short term, there is also a decline in fish prices. This study examines whether the decline in economic activity in the fisheries sector causes changes in the performance of small-scale fisheries, both before and during the Covid-19 pandemic in Tolitoli Regency, Central Sulawesi Province. The target of the research object is fishers who use trolling lines, handline, and beach seine. The analytical method used is Exponential Comparison Method. The results showed that capture fisheries belonging to SSF, which had high performance before covid-19, were fishing gear, and the lowest performance was Surrounding net. On the other hand, the surrounding net has a higher performance during the pandemic than the other three fishing gears, and the lowest is Trolling lines. However, there has been a significant decline in prices and market affordability, the economic contribution of small-scale fishing businesses from before and during the COVID-19 pandemic. For this reason, a policy to open up an export-oriented fish catch market and a wider market reach is required.

The contributions of women to fisheries are often invisible, ignored, and unrecognized even though they represent 47% of the global fisheries workforce, especially in pre- and post-production activities. Poor data systems lead to incorrect assumptions about the gender division of labor in fisheries. This causes the role of women in fisheries to be overlooked. To evaluate the contribution of women in the value chain, a participatory methodology was implemented in three small-scale, fisheries in Mexico: California spiny lobster (Panulirus interruptus) fishery from the northern Mexican Pacific, penshell (Atrina maura) fishery from the Gulf of California, and Caribbean spiny lobster (Panulirus argus) fishery from the Mesoamerican Reef region. This study shows an unequal inclusion of men and women as members of the fishing cooperatives where only 4%, 5%, and 20% are women in spiny lobster, red lobster, and penshell, respectively, and in the distribution of direct jobs (1 out of 6.7 jobs was held by a woman). These results indicate limited opportunities for women to access leadership positions. However, the participation percentages increased dramatically when we considered the fishery system (i.e., both direct and indirect jobs), with women accounting for 43%, 21%, and 37% of the California spiny lobster, penshell, and Caribbean spiny lobster fishery workforce, respectively. Women represented 39% of the workforce in pre-production activities, 2% in production, 29% in post-production, and 56% in complementary to production. Women tended to participate in two or more activities at the same time, generally combining work, household, and community activities. The participation of women in fisheries could be equivalent to a second working day, and even when this effort is present in similarly in three fisheries, their contribution is yet to be acknowledged in order to incorporate women in decision-making. The analysis of the value chain and the fishery system provided a more realistic picture of the contribution of women to fisheries than an analysis focused solely on extraction. This work further analyzed the importance and degree of participation of women in fishing cooperatives and the decision-making process. Strategies to reduce gender disparity are needed to encourage inclusion of women in fisheries decision-making.

Insight Into

Abstract. Folk wisdom tells us that additional time to make a decision helps us to refrain from the first impulse to take the bird in the hand. However, the question why the time to decide plays an important role is still unanswered. Here we distinguish two explanations, one based on a bias in value accumulation that has to be overcome with time, the other based on cognitive control processes that need time to set in. In an intertemporal decision task, we use mouse tracking to study participants’ responses to options’ values and delays which were presented sequentially. We find that the information about options’ delays does indeed lead to an immediate bias that is controlled afterwards, matching the prediction of control processes needed to counter initial impulses. Hence, by using a dynamic measure, we provide insight into the processes underlying short-term oriented choices in intertemporal decision making.
