The present study examined the potential occurrence of the two species off the coast of the Brazilian state of Pernambuco using a multilocus DNA approach, which also provided insights into the conservation status of these stocks in relation to the genetic variation found in both mitochondrial and nuclear regions, analyzed by molecular systematics and population genetics parameters.

The results indicated the presence of only one halfbeak species in the region, reinforced by phylogenetic relationships and population genetics in both mitochondrial and nuclear loci. The conservation status of the stocks in terms of their genetic diversity appears to be good despite the intense exploitation. The results of this study provide a new perspective for the conservation and management of this fishery resource, particularly given the fact that the intensive exploitation over the last five decades appears to have impacted a single species, rather than two.

Species: Hemiramphus brasiliensis, Ballyhoo halfbeak

Analyses of life-history data show that both the size-specific batch fecundities and the age-specific spawning frequencies differ for two halfbeak species, Hemiramphus brasiliensis, the ballyhoo, and H. Halfbeak ages were determined from sectioned otoliths; histological data was used to describe oocyte development and estimate spawning frequency; and batch fecundity was measured from counts of whole oocytes in final maturation. Hemiramphus brasiliensis lived longer 4 versus 2 years and had a higher survival rate Of the two species the larger and longer-lived congener, H.

Gonad development and reproduction of the ballyhoo half beak, Hemiramphus brasiliensis from the coastal waters of Rio Grande do Norte, Brazil. Yamamoto a. The gonad development and reproductive aspects of Hemiramphus brasiliensis from the coastal waters of Rio Grande do Norte, Brazil were verified. This paper presents data on the length-weight relationship, sex ratio, length at first sexual maturity, gonad development, reproductive period and fecundity of H. Females of this species predominated in the sampled population and were larger in size than the males. The length at the first sexual maturation of males was

The ballyhoo halfbeak or ballyhoo Hemiramphus brasiliensis is a baitfish of the halfbeak family Hemiramphidae. It is similar to the Balao halfbeak H. Ballyhoo are frequently used as cut bait and for trolling purposes by saltwater sportsmen. Also known as balahu , redtailed balao , and yellowtail ballyhoo , ballyhoo can be seen above the waters skimming the surface to escape from their predators.
