The lack of available information on fish species surrounding the Galapagos Islands poses a 
problem in assessing their status and the resilience of their populations. For some of the main 
targeted species by the artisanal fishery, there is little more knowledge than a description of 
adult individuals. Data about the larval stages of fish provide efficient means of understanding 
their distribution, growth and early life history. The aim of this study is to identify fish species 
through the establishment of a link between larval morphotypes and their corresponding 
cytochrome oxidase I sequences by DNA barcoding. Subsequent to this, the occurrence, 
abundance and temporal distribution of the determined species throughout the sampling 
stations will be investigated. To our knowledge, this will be the first study to date identifying 
fish larvae in the Galapagos Islands through DNA barcoding. Therefore, the results will provide 
the groundwork for the design of an identification guide of the documented larvae, an 
important tool for further scientific research. Concurrently, the results of the occurrence, 
abundance and temporal distribution of fish larvae will be relevant information for sustainable 
management of the artisanal fisheries and the coastal waters of the Galapagos Islands.
