 In Mexico , the diamond stingray is one of the most important components of Pacific <unk> shark and ray fisheries , comprising around a tenth of the total annual catch . Its significance is likely underestimated , as Mexican fishery reports frequently suffer from <unk> and a lack of species @-@ specific data . It is mainly caught during summer and fall , being the most common ray landed in Bahía Magdalena , and second most common ray landed off Sonora state . <unk> <unk> are the main fishing gear employed ; both adult and juvenile rays easily become entangled in the <unk> by their tail spines , with juveniles known to have comprised most of the Bahía Magdalena catch in 1998 – 2000 . This species is also often caught incidentally in bottom trawls , on <unk> , and in fish traps . In the future , habitat degradation from increasing numbers of shrimp farms may pose an additional threat to this species in the region . As a result of these pressures , the IUCN has assessed the diamond stingray as Near Threatened in Mexican waters . No management schemes have yet been enacted for this species .
