Seven licensed vessels operate in this Mexican fishery – in the waters of the states of Sinaloa and Nayarit – targeting three similar kinds of thread herring (Opisthonema libertate, Opisthonema bulleri and Opisthonema medirastre). 

Thread herring grow to a length of 20 to 30cm. They form dense schools on the surface, feeding mostly on zooplankton. The fleet uses purse seines to catch them, an activity it pursues for 10 months each year.

Three Mexican government agencies help manage the fishery, which brings in a little more than a third of Mexico’s total thread herring landings. Regulations regarding entry to the fishery, gear restrictions, protection of sensitive species, and area closures all contribute to the sustainability of the stocks.

“In recent years, we have taken our products to many countries and different industries, and have found consumers are increasingly concerned about the origin and sustainability of the products they are buying. In order to ensure our product is traceable and sustainable, Maz Sardina decided to enter the thread herring fishery into the MSC assessment process. In the Gulf of California there is already one certified fishery and another in the assessment process, and it is a source of pride for the entire Mexican fishing industry that we are making the effort to achieve this certification.”
