  abstract = {{I}n this study, we examine the effects of connectivity on the total catch of a fishery consisting of two fishing sites when the fish population is a predator of a larger prey-predator system. {T}o this end, we analyze a prey- predator fish community model in a two-site environment and compute catch at {M}aximum {S}ustainable {Y}ield ({MSY}). {W}e exhibit some emergence phenomenon: the total catch can be greater than the sum of the catch at two isolated sites due to connectivity. {T}his result is obtained when the two sites are heterogeneous. {W}e show that the increase in capture at {MSY} is maximal for a certain value of the carrying capacity of the second site, all other parameters remaining constant, including the carrying capacity of the first site. {A} stronger phenomenon can also be observed: even if none of the sites is viable for fishing, the entire system can be viable. {W}e then study the effects of the heterogeneity of the sites and illustrate our results through simulations. {I}t is shown that the excess yield at {MSY} can become very significant when the characteristics of the prey and predator in terms of potential growth are opposite at each site.},
