  abstract = {{M}icrochemical analyses were carried out in order to estimate the {S}trontium:{C}alcium ({S}r:{C}a) ratio in the otolith of the white mullet, {M}ugil curema, in the {P}ernambuco (at the {S}anta {C}ruz channel, {B}razil) in order to determine its connectivity between the estuary and ocean. {V}ariation in the otolith {S}r:{C}a ratio was directly related to salinity, with greater salinity denoting a higher otolith {S}r:{C}a value. {D}ata on the otolith {S}r:{C}a ratio demonstrates that the individuals analyzed are born in areas of salinity that are characteristic of the estuary, where they develop until approximately one year of age, at which point they migrate to areas of greater salinity until reaching sexual maturity (3 years of age) in the sea. {S}pawning occurs in the ocean, after which {M}. curema individuals may either remain or return to the estuary until the next spawning. {D}ifferences in estuarine salinity were found for young of-year individuals and may be related to the season when spawning took place, since {M}. curema females are found spawning throughout the year. {T}he hypothesis is that higher salinity in the dry season leads to a greater otolith {S}r.{C}a signature among individuals spawned in this season from birth until one year of life. {O}n the other hand, the lower salinity in the rainy season leads to a lower otolith {S}r:{C}a signature among individuals spawned in this season. {T}hese information are important for the adequate management of the white mullet stock in northeastern {B}razil.},
