| [spatio-temporal dynamics of fishing effort in a multi-species artisanal diving fishery and its effects on catch variability: insights for sustainable management]. | artisanal diving fisheries are a source of income, employment and food security of coastal areas in many countries. understanding the dynamics of these fisheries, including the spatial and temporal dynamics of fishing effort, gears and species can help to address the challenges involved in fisheries management. we aimed to analyze the differences in fishing strategies undertaken by fishers that use two different diving methods (hookah and free diving), the conditions and their potential impacts ... | 2014 | 25720188 |
| heavy metals in sediments and lobster (panulirus gracilis) from the discharge area of the submarine sewage outfall in mazatlán bay (se gulf of california). | concentrations of selected heavy metals in lobster (panulirus gracilis) tissues and sediments (bulk and bioavailable fractions) from an area influenced by sewage discharge in mazatlán bay were determined. cd, cu, fe, pb, and zn in the sediments showed enrichment factors higher than one related to the discharge and were higher than the lower values of the sediment quality guidelines proposed by noaa and ccme. in addition to the high levels, relatively high bioavailability in the sediments was est ... | 2004 | 15253046 |
| [reproductive pattern and mean size of sexual maturity of female lobsters panulirus gracilis (decapoda: palinuridae) in playa lagarto, guanacaste, costa rica]. | the lobster p. gracilis is important as a fishery resource and also contributes to food security of fishers in coastal communities in the north pacific of costa rica. due to the importance of updating knowledge related to the reproductive pattern of this species, we analyzed 357 specimens of female lobsters caught by the fishing methods of "hookah" and lung diving, from november 2007 to october 2008 in playa lagarto. furthermore, we examined the size composition by depth; monthly pattern of repr ... | 2012 | 23342528 |
