Abstract
Exploitation of the cannonball jellyfish (Stomolophus sp. 2) is increasing in Mexico and USA due to successful fisheries associated with seasonal blooms in coastal areas. Previously, it was proposed that such blooms could be identified by recognizing the presence of young stages in the water. In our work, we aim to describe the young stages (ephyra and metaephyra) found in the Las Guásimas lagoon, Sonora, Mexico. The description of specimens is based on photographs, drawings, and morphological measurements aimed at helping in the early detection of blooming events.
Highlights
In Western countries, jellyfish are usually associated with bad memories, mostly due to the stings these marine animals can inflict on humans [1,2,3,4]; in Eastern countries, jellyfish are synonymous with a fine dish or delicacy [5,6,7,8], and eventually have been associated with many medicinal properties [9]
We examined a totalstages of 28 samples andephyrae
Ephyrae were only found during thearise winter and (No sword-like, broadly oval, or breadknife-shaped)
Summary
In Western countries, jellyfish are usually associated with bad memories, mostly due to the stings these marine animals can inflict on humans [1,2,3,4]; in Eastern countries, jellyfish are synonymous with a fine dish or delicacy [5,6,7,8], and eventually have been associated with many medicinal properties [9]. The use of jellyfish as food has long been recognized in many places. It is only recently that Western countries have recognized its importance as an economic product [10,11,12]. Jellyfish fisheries have been developed, and declined [13], due to different factors (e.g., fluctuation of stocks or lower interest of fishery companies), but some countries are fortunate to have certain valuable species in their territorial waters.
