TLDR
Holistic approaches, including parasites as biological tags for stock delineation will render valuable information to help insure fisheries and marine ecosystems against further depletion and collapse.Abstract:
Many marine fisheries in South American Atlantic coasts (SAAC) are threatened by overfishing and under serious risk of collapsing. The SAAC comprises a diversity of environments, possesses a complex oceanography and harbours a vast biodiversity that provide an enormous potential for using parasites as biological tags for fish stock delineation, a prerequisite for the implementation of control and management plans. Here, their use in the SAAC is reviewed. Main evidence is derived from northern Argentine waters, where fish parasite assemblages are dominated by larval helminth species that share a low specificity, long persistence and trophic transmission, parasitizing almost indiscriminately all available fish species. The advantages and constraints of such a combination of characteristics are analysed and recommendations are given for future research. Shifting the focus from fish/parasite populations to communities allows expanding the concept of biological tags from local to regional scales, providing essential information to delineate ecosystem boundaries for host communities. This new concept arose as a powerful tool to help the implementation of ecosystem-based approaches to fisheries management, the new paradigm for fisheries science. Holistic approaches, including parasites as biological tags for stock delineation will render valuable information to help insure fisheries and marine ecosystems against further depletion and collapse.read more

Why ignoring parasites in fish ecology is a mistake
Juan T. Timi,Robert Poulin +1 more
TL;DR: Given the impact of parasites across all levels of biological organisation, it is shown that their omission from the design and analyses of ecological studies poses real risks of flawed interpretations for those patterns and processes that ecologists seek to uncover.

Helminth parasites of South American fishes: current status and characterization as a model for studies of biodiversity.
TL;DR: The closest true estimations of species diversity and distribution will rely on further studies combining both molecular and morphological approaches with ecological data such as host specificity, geographical distribution and life-cycle data.

Conceptual and practical advances in fish stock delineation
Alfonso Pita,John Casey,Stephen J. Hawkins,Manuel Ruiz Villarreal,María-José Gutiérrez,Henrique N. Cabral,Fabio Carocci,Pablo Abaunza,Santiago Pascual,Pablo Presa +9 more
TL;DR: The fish stock delineation concept has now evolved informed by knowledge affordable from a variety of new genetic and geochemical life cycle tracers in addition to traditional morphometric, parasitological and life history trait approaches as discussed by the authors.

Parasites in fisheries and mariculture.
Juan T. Timi,K. MacKenzie +1 more
TL;DR: The relationship of parasitology with mariculture practices, which are carried out mostly on artificial and controlled systems, follows a more classical approach, focusing on the development of strategies of prevention, management and control of pathogens.

Fishing Down Marine Food Webs
TL;DR: The mean trophic level of the species groups reported in Food and Agricultural Organization global fisheries statistics declined from 1950 to 1994, and results indicate that present exploitation patterns are unsustainable.

TL;DR: Zoning the oceans into unfished marine reserves and areas with limited levels of fishing effort would allow sustainable fisheries, based on resources embedded in functional, diverse ecosystems.
