Early growth and recruitment in Atlantic mackerel Scomber scombrus: discriminating the effects of fast growth and selection for fast growth

Continuous genetic selection and improvement in nutrition have led to a very fast growth rate in modern strains of broiler chickens. Metabolic disorders such as ascits, sudden death syndrome and leg problems are related to a rapid early growth rate in poultry, especially in broilers, and their incidence can be decreased by slowing early growth. The use of management tools to reduce metabolic disorders that rely primarily on decreasing feed consumption, The feed restriction programs is on of the main techniques in growth curve manipulation for increasing production efficiency in broiler chicken in alleviate the incidence of some metabolic disorders and can be used to reduction the unfavorable effects of fast growth rate in broiler chicken production industry, and could be profitable in broiler chickens production efficiency. This article implicated on new findings in about different feed restriction programs effects on these problems in broiler chickens.

Scomber Scombrus

The microhabitat and morphology of Grubea cochlear (Monogenea), a rare gill parasite of Atlantic mackerel (Scomber scombrus), were investigated for a sample of fourteen parasite individuals obtained from Lyme Bay, southern England. Grubea cochlear showed a preference for the inner hemibranch of the fourth gill arch, this localization contrasting with that of the related and sympatric species Kuhnia scombri. The morphology of G. cochlear in this sample differed slightly from some of the previously documented specimens, especially with regard to the number of small genital hooks and the relative size of the haptor. It is suggested that geographical morphological variation may occur in this species.

Lower Temperature

Refrigerated sea water proved to be an improved method of holding Atlantic mackerel (Scomber scombrus). The uniform lower temperature and reduction in available oxygen retarded the development of oxidative rancidity. Textural deterioration was also retarded. The sodium uptake from and the potassium loss to the sea water was not excessive, and taste panelists could not consistently identify samples with elevated sodium content. The addition of carbon dioxide to the RSW did not regularly affect the level of spoilage as monitored by the measurement of trimethylamine. The values, however, were low for all holding systems, even after 9 days. The presence of dissolved carbon dioxide in the fish muscle made the fish unacceptable for canning.
