یکی از مهم ترین اطلاعات لازم در برآورد مدل های ارزیابی ذخایر، اطلاع از ضرایب رابطه طول و وزن یک گونه می باشد. در این مطالعه نتایج رابطه طول و وزن ماهی شیر (scomberomorus commerson) در سال های 1382 تا 1385 جهت بررسی روند تغییرات ضرایب a و b بر اساس رگرسیون غیرخطی مورد ارزیابی قرار گرفت. مقدار ضریب b به ترتیب سال؛ 76/2، 74/2، 70/2 و 71/2 برآورد گردید. همچنین نتایج نشان می دهد بین تغییرات ضرایب a ...
Tulang ikan tenggiri (Scomberomorus commerson) merupakan salah satu limbah industri pengolahan yang dapat digunakan sebagai sumber mineral. Pada penelitian ini tepung tulang dimanfaatkan bahan pengisi pada pembuatan kukis dan diharapkan mampu meningkatkan kandungan nutrisinya. Tujuan untuk mengetahui pengaruh fortifikasi terhadap sifat fisik, kimia mutu sensori (hedonik) dihasilkan. Kukis dibua...
This study histologically describes the intersexuality of Scomberomorus niphonius collected from the coastal area near Jeju Island. A total of 126 S. niphonius, collected from March to July 2012 with a total length of 62.4 cm (±17.5) and a total weight of 1,701.9 g (±1,528.9) were used for analyses. From a histological perspective, two types of intersex were confirmed. One type had scattered ge...
The aim of this study was to comparing the effect of different hanging ratios (E=0.5 and 0.6) of drift gillnets on catch rates, length composition and Catch per Unit Effort (CPUE) in Bushehr coastal waters between late September 2010 to late March 2011. The length frequency of Spanish Makerels did not differ significantly between gillnets with 0.5 and 0.6 hanging ratios (P>0.05). A total of 558...
The objective of the present study was to determine the effects of fish aggregation device (FAD) deployment on biodiversity, catch composition and length frequency distribution in the Qeshm Island handline fishery. Two FADs were deployed in the Qeshm Island. Four biodiversity indices including Margalef, Shannon-Weaver, Simpson and Pielou and also catch composition and length frequency distribut...
In the current study, the relationships between functional properties and average molecular weight (AMW) of collagen hydrolysates from Spanish mackerel (Scomberomorous niphonius) skin were researched. Seven hydrolysate fractions (5.04 ≤ AMW ≤ 47.82 kDa) from collagen of Spanish mackerel skin were obtained through the processes of acid extraction, proteolysis, and fractionation using gel filtrat...
