Synopsis (short abstract) This document is prepared for fisheries biologists, managers and administrators concerned with lagoon fisheries and aquaculture. Our main objective is to draw attention to the need for greater understanding of relationships between the hydraulics and productivity of lagoon fish and shellfish. The fishery yields from lagoons vary widely, and, probably, predictably, once such relationships are understood. Furthermore, the productivities of many lagoons could probably be enhanced by hydraulic manip ulations, but the hydraulic manipulation is presently risky, except in dystrophic lagoons. The document includes a description of lagoon physics, how hydraulics are likely linked to lagoon productivity, how lagoons might be expected to respond to hydraulic alterations, and a protocol for physical investigations. This latter is a necessary step to protect as well as enhance fisheries and aquaculture resources in lagoons, which are especially vulnerable to degradation and overexploitation.

    Some considerations for the management of coastal lagoon and estuarine fisheries 1981

    Management of artisanal fisheries in coastal lagoons and estuaries is treated in three broad categories -- regulatory management, non-regulatory management, and interactions between fisheries or fishery interests. Regulation of artisanal fisheries in coastal lagoons and estuaries by government authority is hampered for several reasons. Technical and financial constraints on government severely limit enforcement capabilities. S ocio-economic considerations, chiefly the lack of alternative employment opportunities for fishermen, preclude the adoption of many of the classical regulatory management techniques. As a means to complement or supplement management by central government authority, revitalization of local traditional authority is advocated. Non-regulatory management, the application of methods which increase capture and culture fishery potenti al through manipulation of the environment, is illustrated by various kinds of hydraulic engineering, predator control, stocking, artificial nursery areas, and brush-park fisheries. Interactions between fisheries or fishery interests is treated at several levels. Considered are competition between groups of fishermen of different ethnic and economic backgrounds, interactions between artisanal capture fisheries and aquaculture, and competiti on between artisanal fisheries of coastal lagoons and estuaries and off-shore shore industrial fisheries which fish the same stocks.

    Mediterranean coastal lagoons: sustainable management and interactions among aquaculture, capture fisheries and the environment 2015

    The Mediterranean region hosts around 400 coastal lagoons, covering a surface of over 641 000 ha differing in both their typology and use. Fisheries and various forms of aquaculture have been traditionally carried out in Mediterranean coastal lagoons since ancient times and are part of the cultural heritage of the region. Traditional lagoon management linked to extensive aquaculture and fish harvesting has certainly contributed, over time, to preserve these peculiar ecosystems, although much of the coastal lagoon areas have progressively disappeared due to land reclamation and other uses. Recently, coastal lagoons have become a relevant environmental concern: land claiming, pollution and the lack of management, among other factors, have strongly modified both the structure and functioning of these sensitive coastal ecosystems. In particular, the management of traditional aquaculture and capture fisheries activities has been identified as the main instrument to maintain lagoons’ ecolog ical features and to prevent the degradation of their sensitive habitats, both from an environmental and socioeconomic point of view. To guarantee the sustainability of aquaculture and capture fisheries in lagoons, proper management plans should be established so as to ensure the preservation of both biodiversity and local knowledge. This should also be considered as a fundamental pillar for any programme aiming at the preservation and restoration of lagoons’ environment.
