“…These show a clear population structure throughout their distribution with a latitudinal variation in their meristic and morphometric characteristics (Hubbs 1925;McHugh 1951;Miller 1956 . 2005).…”

The taxonomic status of hake (Merluccius spp.) in the northeastern Pacific is unclear. Hakes in this region are Merluccius productus, M. angustimanus, M. hernandezi, and a morphotype known as dwarf hake. Of these, only the first two species are currently valid. Descriptions in previous studies have been limited by overlapping morphological characteristic, lack of biological material, and limited numbers of sampling localities. To clarify their taxonomy, 461 hake were obtained from eight localities along the North American coast for morphological and mitochondrial DNA sequence analyses (cytochrome b, cytochrome c oxidase subunit I, and 16S ribosomal rDNA). Morphological and molecular analyses suggest that hake in this region represent a continuum of a single species with some levels of morphological and genetic intra-specific variation. In light of these results, we propose that M. productus is the only species of hake present along the North American and northern Central American coast.

“…Proportions support this latter hypothesis better than ineristie characters do, Numbers of meristic characters are strongly influenced by other factors, as well as water temperature. The number of gill rakers is directly proportional to head size in PaciBc herrings ( McHugh, 1954), in the genus Opisthonenia ( Berry and Barrett, 1963), and in menhadens. B. patronus has a shorter but deeper head than turannus when expressed as per cent of standard length, and their gill raker counts correspond ( Fig.…”

“…Feeundity is related to body size and, therefore, to water temperature. McHugh ( 1951) demonstrated that a decrease in fecundity to the south was related to body size in the northern anchovy (Engraulis mordax). B. tyrannus produce from 38,000 to 631,000 ova each season ( Higham and Nicholson, 1964).…”

Western North Atlantic menhadens, genus Brevoortia, comprise two well-defined groups, four species, several races, and two hybrid combinations. One group, the large-scaled menhadens, live in temperate waters and are represented by B. tyrannus in the Atlantic Ocean and B. partonus in the Gulf of Mexico. B. tyrannus occurs in the Atlantic from Nova Scotia to Jupiter Inlet, Florida. Populations include a spring-spawning race north of Long Island, N.Y., an autumn-spawning race on the coast between Long Island and North Carolina, and a winter-spawning race in the Indian River area of Florida. Evidence also indicates the existence of a southern Atlantic population that ranges from North Carolina to northeast Florida. B. patronus ranges from southwest Florida along the gulf coast to Veracruz, Mexico. The large-scaled manhadens support the fish oil and fish meal industry of the Atlantic and guif coasts of the U.S. The small-scaled menhadens are limited to warm-temperate waters. An Atlantic population of B. smithi is known from North Carolina to Jupiter Inlet, Florida. A gulf population of B. smithi ranges from Florida Bay to Louisiana. The western gulf cognate, B. gunteri, occurs between Louisiana and the Gulf of Campeche and may extend into the Caribbean. Two hybrid combinations are known. B. smithi x B. tyrannus ranges on the Atlantic coast from Sapelo Island, Georgia, to Jupiter Inlet, Florida. B. smithi x B. patronus ranges on the gulf coast from Florida Bay to Port St. Joe, Fla. Evidence is presented that B. tyrannus in the Indian River of Florida is modified by introgression. This study presents a key to the menhaden species and hybrids, describes the various forms, presents synonymies and recent references, and discusses hybridization, geographic variation, population structure, and zoogeography.

“…Due to the relevant data obtained with electrophoretic studies and the relative ease with which they are obtained, these surveys have beenwidely used to identify the population structure of various fish species of different genera (Sodsuk et al, 1995;Macaranas et al, 1996;Engelbrecht and van der Bank, 1997) and, in particular, of the genus Engraulis (Altukov et al, 1969;Fujio and Kato, 1979;Grant, 1985;Spanakis et al, 1989;Oezdamar et al, 1994;Bembo et al, 1996). McHugh (1951), based on morphometric andmeristic studies, established three populations of the northern anchovy E. mordax, corresponding to specific areas of its distribution in the northeastern Pacific: the northern, central and southern populations. This subdivision ( fig.…”
