The fishing zone 90 is located in the Gulf of Tehuantepec and this is composed of five sub-sectors from S-91 to S-95. The “Oaxaquena Coast” is located between Salina Cruz City and The Boca de Tonala (in the Mar Muerto lagoon sytem), where the S-91 and S-92 sub-sectors are located. The “ Chiapaneca Coast” is located between the Boca de Tonala and Puerto Chiapas, where the S-93, S-94 and S-95 sub-sectors are located. From S-91 towards S-95 sub-sectors the total catch of shrimp resource increased from 160 to 1,030 Kg, coincided with a descendent gradient of gravel and an ascendant gradient of mud (g). Sand was present in all sub-sectors, but was not dominant at the coast level except towards the oceanic front. Based on geographic information system techniques, at the fishing zone 90 two shrimp harvest sub-systems were observed and delimited. The first of those is the “Oaxaquena Coast” where was recorded a lower shrimp catch level with gravel dominant in the S-91 sub-sector and a gravel-sand mix in the S-92 sub-sector. The second the “ Chiapaneca Coast” where was recorded a higher shrimp catch level with mud dominant in the S-93,
