Fish consumption in Mexico is considered low (around 12 kg per person per year) and non-homogeneously distributed across the country. One of the reasons for this situation is the scarcity of wholesale selling sites. In this context, the Mercado del Mar (MM), located in Guadalajara city, Jalisco, is the second biggest wholesale fish market in Mexico, with a distribution of about 500 tons per day and a variety of about 350 different species of fish. In this paper, we argue that MM has accumulated social capital, which is formed from two main resources: buyer and seller relationships, and reputation. Specifically, the MM manages a broad and intensive interaction among business actors and the already achieved reputation allows the MM to adapt to market changes. To validate our hypotheses, an empirical study was conducted in 2015 by means of interviews to fish wholesalers in the MM and a sample of their suppliers and buyers. For simplicity we have only considered fresh water fish. We have followed snow-ball sampling as the survey strategy. Results show that the MM has responded to fish market dynamics organizing a complex network of buyers and suppliers whose relationships can be explained in the form of strong and weak ties. At the same time, reputation has been the central resource to build this social capital and also gives place to market transactions. Additionally, the strategic position of Guadalajara city and the well-connected routes have facilitated fish bulking and distribution in the region.

This study aims to construct a theoretical framework to analyze the elements of the network structure and the relationship system within the seafood supply chain. The scope of the investigation is to evaluate how these elements influence the flow of products and the efficiency of the seafood supply chain and why these social interactions can create value and enhance competitive advantage. The model combines the resource- and knowledge-based view and the social network analysis applied to seafood supply chains. To demonstrate the application of the model, two theoretical examples and a real case study of the Mercado del Mar in Guadalajara, Mexico, are used. Primary data are obtained from semi-structured interviews, social network analysis metrics, and qualitative analysis. Findings are based on the analysis of theoretical examples and must be considered with caution. Nevertheless, the observations in the examples and case study provide new arguments to the relationship between the pattern of interrelationship and the efficiency of a supply chain. This study emphasizes the necessity of combining quantitative and qualitative analyses to understand and explain real-life supply networks.

A growing body of critical social-scientific scholarship addresses the implications of marine spatial planning for those who depend on the ocean for their livelihood, sustenance, well-being and cultural survival. Of particular concern are planning initiatives that construct marine space in ways that negate or contradict its particular materiality, the latter holding great significance for how different actors relate to the ocean. In response, scholars are turning towards relational conceptualisations of marine space, focusing on the relationships between human and non-human actors, as well as the factors that mediate them. Here, we argue that legal geography, a strand of interdisciplinary research that explores how space, law and society are co-constituted, can make a valuable contribution to this discussion. In taking seriously the connections between the themes law as discourse, law as representation and law as power, legal geography offers a deeper understanding of the subjectivities, narratives and sources of normativity made in/visible by the legal dimensions of planning frameworks. Using the legal-geographical concept of spatial justice as our frame of reference, we posit that the relational materiality of the ocean lends itself to the socio-legal construction of marine spaces as 'commons', i.e. as pluralist spaces where different knowledges and ways of being coexist and intermingle, and where well-being is perceived in composite, socio-natural terms. This allows us to problematise marine spatial planning, along with its normative, regulatory and institutional underpinnings, as a vehicle for the enclosure of not only marine spaces but also spaces of decision-making.

Several studies have shown that the performance of a supply chain is heavily influenced by the pattern of relationships among firms. This paper analyzes the structure of relationships (network topology) that leads to the highest agility of a food supply chain when sudden demand changes occur. To do this, a simulation model that represents a supply chain and specific rules to allocate orders is built. The supply chain in the model follows the specific characteristics of trade in the primary sector. The model is fitted to the conditions of a real seafood supply chain in Mexico. Agility is measured through the effect on the order fulfillment of a sudden demand shock and the recovery time of this rate to previous values. The simulation results show that the most suitable structure depends on how product is distributed among suppliers. If product is evenly shared, supply chains with homogeneous topologies are more agile than supply chains with heterogeneous topologies, but the result is the opposite if product is unevenly shared among suppliers. Other previous recommendations, such as having multiple suppliers and horizontal links, are confirmed by the simulations. These findings contribute to the general debate on which is the optimal topology for an agile supply chain.

The COVID-19 pandemic has abruptly transformed all social structures around the world, and coastal zones where tourist and fishing activities take place is no exception. Due to the sanitary measures, restrictions to travel and lock down periods, the tourist sector has been one of the economic sectors most affected by this health and economic crisis. However, it is not the only sector to have been affected, the fisheries sector, being highly dependent on the export market, has also suffered the consequences of this crisis. In this article, we aim to identify the main characteristics and key aspects of the fishing and tourist sectors in the states of Yucatan and Campeche, in Mexico, under pandemic dynamics. What are the organizational and governance structures that have been developed in response to this world phenomena? To answer this question, we conducted phone interviews and reviewed governmental and community actions. Results show that individual survival strategies prevail as a response to COVID-19, over community or governmental actions. There was limited coordination among the different governance structures, between the community and governmental levels. However, this crisis has also been a period of learning and innovation to implement adaptive governance structures to build resilience and a “new normal social reality”.
