Some reproductive patterns of the sardine, Sardina pilchardus (Walb, 1792), in Boka Kotorska Bay (Montenegro, southern Adriatic Sea)
The annual alteration of gonad morphology in sardine (Sardina pilchardus, Walbaum 1792) caught in the period from November 2006 to October 2007 using beach seines in the region of Boka Kotorska Bay (Montenegro, southern Adriatic) was studied. Samples were taken in the middle of each month. Total length of individuals ranged from 8.7 to 14.7 cm and weight ranged from 4.67 to 22.61 g. Their gonad...
متن کاملDiet and feeding intensity of sardine Sardina pilchardus: correlation with satellite-derived chlorophyll data
Spatio-temporal variability of the diet of sardine Sardina pilchardus off Portugal was examined through analysis of the stomach contents of fish collected every 14 d from the west and south of Portugal during 2003/2004. Dietary composition of the modal sardine length class was assessed by determining the frequency of occurrence and carbon content of identified prey, and these 2 parameters were ...
متن کاملEvaluating fishermen’s conservation attitudes and local ecological knowledge of the European sardine (Sardina pilchardus), Peniche, Portugal
BACKGROUND European sardines are an important fishing resource in the North Atlantic. Recognized for its great commercial and economic value in southern Europe, this resource currently has low stock indices. From this perspective, fishers' local ecological knowledge (LEK) is appreciated as an auxiliary tool in the management of sardines in this region. Our goal is to evaluate the LEK and attitu...
متن کاملProteolysis of Sardine (Sardina pilchardus) and Anchovy (Stolephorus commersonii) by Commercial Enzymes in Saline Solutions.
Fish sauce production is a very long process and there is a great interest in shortening it. Among the different strategies to speed up this process, the addition of external proteases could be a solution. This study focuses on the effect of two commercial enzymes (Protamex and Protex 51FP) on the proteolysis of two fish species traditionally converted into fish sauce: sardine and anchovy, by c...
متن کاملInfluence of variable catch factors on sardine population level in eastern Adriatic tested by System Dynamics
System perspective can be applied to the fishery management. Therefore investigation of sardine population behaviour dynamics by system dynamics methodology is presented in this paper. The model is based on Schaefer production model and available biological data was used for sardine in the Adriatic Sea. The Schaefer production model is often applied in order to submit behavior dynamics of fish ...
