The researchers reported finding fewer hake and anchovy eggs than usual in the most recent CalCOFI surveys.
Horne and Smith (1997) argued that the spawning locations of Pacific hake shifted north in warmer years and had moved 444 km toward the north between 1951 and 1984, based on modeling using CALCOFI collections of larval hake.
Details of the CalCOFI sampling area, gear, and methods are available in the literature (Kramer et al.
4 mm, preflexion through early postflexion stage) from the CalCOFI survey were assigned tentatively to a unique unidentified type on the basis of similarities in morphological features and pigmentation pattern.
In July 2004, 2 dedicated marine mammal visual observers were added to the CalCOFI cruises (CalCO-FIb), and a standard line-transect protocol replaced the strip-transect protocol (Burnham et al.
For all CalCOFI surveys, observations were made on daytime tracklines between stations, and no visual observation effort was conducted while the vessel was stationary.
Ellos encontraron que de la region 16 a 18 del plan CalCOFI (frente a Bahia Magdalena y Punta Eugenia), el maximo de BZ se registro en primavera.
En el area que comprende desde Monterey, California a Bahia Magdalena, Mexico, durante el periodo de 1951 a 1989 Hernandez-Vazquez (1995) encontro homogeneidad mensual y latitudinal entre las latitudes 22 a 38[grados]N, con un minimo entre octubre y marzo (invierno) y un maximo de mayo a julio (primavera-verano); los resultados de este trabajo y los de Hernandez-Vazquez (1995) coinciden en la variacion mensual, pero no en la de tipo estacional, probablemente debido a que este ultimo autor empleo toda la base de datos de CalCOFI de la BZ, lo que minimiza la variancia.
Marine mammal surveys on CalCOFI cruises are conducted quarterly, along predetermined transect lines between oceanographic water sampling stations (Fig.
Tokyo) to sight, identify, and estimate group sizes of cetaceans and pinnipeds encountered along the transect lines between CalCOFI hydrographic sampling stations (Fig.

2009), partly because of the concern that measurements within the current CalCOFI sampling pattern may not be representative of conditions for the entire range of the stock.
