Feeding strategy and cannibalism of the Argentine hake Merluccius hubbsi
Journal of Fish Biology, 2011 The diet composition and feeding strategy of the Argentine hake Merluccius hubbsi in the San Matías Gulf were analysed in order to use this information for the sustainable management of the fishery. Merluccius hubbsi behaved as an opportunistic predator. Small M.

Development of the digestive system of Argentine hake,
AbstractThe Argentine hake Merluccius hubbsi is an important fishery resource of the Southwestern Atlantic Ocean and it is also a potential species for cultivation. In this work, the digestive system development in field‐caught hake larvae was studied using histological and histochemical approaches.

Larval development of Argentine hake Merluccius hubbsi
Journal of Fish Biology, 2009The ontogeny of the developmental stages of the hake Merluccius hubbsi is described. Fish larvae and post‐transitional juveniles were collected in the Nor‐Patagonian area from 1989 to 2004. The opening of the mouth and the pigmentation of the eyes are coincident with yolk resorption, finishing the yolk‐sac stage.

Acid phosphatase activity in pre- and post-spawning hake (Merluccius Hubbsi)
Comparative Biochemistry and Physiology Part A: Physiology, 19871. The specific activity of muscle acid phosphatase (E.C. 3.1.3.1.) in pre- and post-spawning hake was investigated. 2. Specific activity values, 0.54 in pre-spawning hakes and 1.64 in post-spawning fish, have been obtained. 3. Using a histochemical test, acid phosphatase has been localized mainly in the connective tissue.

SSU rDNA analysis of Kudoa rosenbuschi (Myxosporea) from the Argentinean hake Merluccius hubbsi [PDF]
Diseases of Aquatic Organisms, 2005 The cloning and sequencing of the small subunit (SSU) ribosomal DNA gene from Kudoa rosenbuschi (myxosporean species associated with post-mortem myoliquefaction process in the Argentinean hake Merluccius hubbsi) is reported. The SSU rDNA was found to contain 1740 bp with a single polymorphic site with either a C or T at position 221.

Reproductive pattern of the Patagonian stock of Argentine hake (Merluccius hubbsi)
Fisheries Research, 2005Abstract This study is the first analysis of the spatial distribution pattern of Patagonian hake during the spawning period, from December to March. In December, spawning females were concentrated in a small area located between 43° and 44°S. During January and February, reproductive activity expanded to the southern area, three main spawning ...

Spawning and reproductive potential of the Northern stock of Argentine hake (Merluccius hubbsi)
Fisheries Research, 2010Abstract The reproductive activity of the Argentine hake Merluccius hubbsi Northern stock takes place mainly during autumn and winter in the Argentine Uruguayan Common Fishing Zone (AUCFZ) (34°30′–39°30′ S and 52–59° W). At the present scarce information about spawning pattern and reproductive potential of M.

Storage life of chilled Patagonian hake (Merluccius hubbsi)
International Journal of Food Science & Technology, 1980SummaryThe storage life of iced Patagonian hake (Merluccius hubbsi) was studied. Seasonal changes were investigated by means of organoleptic assessments (raw and cooked), total volatile bases (TVB) and pH.During summer‐time (December to March) the keeping time, from the edibility point of view, for round hake in ice is not more than 9 to 10 days; in ...

Spawning aggregations of Merluccius hubbsi, in Patagonian waters: evidence for a single stock?
Fisheries Research, 1993Abstract From 1971, a small scale bottom trawl fishery has developed in the San Matias Gulf (41°–42° S; 64°–65°W) of the Argentinean Sea, targeting the hake (Merluccius hubbsi Marini). The dynamics of a spawning aggregation of hake in the gulf were analyzed based on changes in sex ratio and the proportions of different stages of sexual maturity.
