Sustainability and economic consequences of creating marine protected areas in multispecies multiactivity context

Seamount influences on mid-water shrimps (Decapoda) and gnathophausiids (Lophogastridea) of the South-West Indian Ridge

“…As a result of historical overfishing and subsequent collapse, some of the fish populations on the SWIR may be in a state of recovery, the rate of which will depends partly on energy input and prey accessibility (Kar and Ghosh, 2013). Moreover, population connectivity and the potential 'island' effect of seamount will have relevance for replenishment and for the capacity of population to resist any depensation (Courchamp et al, 2008) at low densities arising from the allee effect (Stephens et al, 1999).…”

Dynamics of predator-prey models with refuge, harvesting and dispersal

“…Several authors have studied predator-prey models with harvesting functions that are constant, linear or rational [5,9,15]. Two and three-dimensional model with linear harvesting and/or refuge, as well as harvesting with the habitat divided in two patches have been studied in [2,6,7,14]. A detailed study of the impact of harvesting in one or both species and its relationship to maximum sustainable yield is given in [4,8].…”

Stability Analysis of a Biological Model of a Marine Resources Allowing Density Dependent Migration

“…Dubey [4] proposed a mathematical model to study the role of a reserved area on the dynamics of the predator-prey system. Kar and Chakraborty [5], [6] and [7] considered a predatorpredator model with prey dispersal in a two-patch environment, one of which is a free fishing zone and another is a zone protected. They described the different consequences of the reserve using numerical simulations.…”
