“…The majority of fishes are gonochoristic and have various sexually dimorphic characteristics in their secondary sexual characteristics 30 . Distinguishing characteristics for the morphological qualities of many teleosts have been documented, including body color, ornamental patterns, breeding tubercles on the snout, pectoral fins and scales, fin hooks, body shape, fin size and shape [31][32][33][34][35] .…”

يعد إزدواج الشكل الجنسي وعلم الأحياء الإنجابي من الجوانب الأساسية لدراسات تربية الأسماك. كان الهدف من هذا البحث هو تحليل إزدواج الشكل الجنسي والبيولوجيا الإنجابية لـ N. notopterus. تم جمع ما مجموعه 74 N. notopterus من نهر كيليكار في منطقة أوغان إلير، إندونيسيا، وتتكون من 38 ذكرًا (طول الجسم: 18-23.6 سم؛ وزن الجسم: 35.1-92.1 جم) و36 أنثى (طول الجسم: 19.6-26.3 سم؛ وزن الجسم: 35.1-92.1 جم) و36 أنثى (طول الجسم: 19.6-26.3 سم؛ وزن الجسم: 49.4-133.8 جم). تم تحليل سبعة عشر شخصية مورفومترية وثلاثة صفات مرسية وخمسة معايير بيولوجية إنجابية. أظهرت النتائج وجود اختلافات في الخصائص المورفومترية للذكور والإناث N. notopterus. ومع ذلك، لم يكن هناك اختلاف في الشخصيات المرسية. ويتراوح مؤشر الغدد التناسلية عند الذكور من 0.15 إلى 0.61%، وعند الإناث من 1.12 إلى 9.10%. تراوح المؤشر الكبدي عند الذكور من 0.19 إلى 1.38%، وتراوح عند الإناث من 0.15 إلى 1.23%، مع نسبة جنس 1.056:1، وخصوبة 1.007-3.901 بيضة، وأقطار البويضات 1.1-3.9 ملم، ومستويات النضج. من الغدد التناسلية المتطورة لتنضج عند الذكور وتنضج لوضع البيض عند الإناث. في الختام، يمكن تحديد الاختلافات بين الذكور والإناث N. notopterus شكليا.

This study examined the age distribution and growth characteristics of the striped eel catfish (Plotosus lineatus), which is an invasive alien species in the eastern Mediterranean. A total of 1,011 samples were collected from Iskenderun Bay (Turkey), with lengths ranging from 5.1 to 16.8 cm, predominantly comprising females (1:1.92). Age 3 represented the majority in the population (52.03%). The value of the scaling exponent “b” of the length-weight relationship was less than “3” for both sexes (females: 2.28; males: 2.26; combined: 2.27). The results for the von Bertalanffy growth parameters were observed for the combined sexes as, L∞ = 24.9934 cm, k = 0.1718 year−1, and t₀ = −1.7707 years. The striped eel catfish populations in Iskenderun Bay exhibited negative allometric growth patterns and were predominantly composed of adult individuals. This study presents the dataset on the length-weight correlations, age-growth characteristics, and von Bertalanffy growth parameters of Plotosus lineatus in the Mediterranean Sea, thereby significantly contributing to comprehending the stock dynamics. It is anticipated that this study will make a significant contribution to the management of P. lineatus stocks, given its invasive nature.
