Reproductive biology of Siganus rivulatus (Forsskal, 1775) in the Red Sea, Suez Canal and the Mediterranean Sea, Egypt

Abstract

The reproduction of a fish species is very important for the assessment and management of its stock (Froese, 2004). Therefore, the reproductive strategy of the species is one of the most important biological characters to be studied to manage fisheries resources. It gives a predictable future for fish production and recruits adding for the recent stock (El Ganainy, 1992; Dinh, 2018). Since the completion of the Suez Canal in 1869, several Red Sea species invaded the Mediterranean Sea and known as the Lessepsian migrant species (Por, 1978). Family Siganidae (rabbitfish) is ARTICLE INFO

Aspects of fecundity of some fishes from the Sudanese coast off Suakin

“…According to Nandikeswari et al (2014) [24] , the fecundity of Terapon jarbua from the Bay of Bengal ranged from 13,475 to 115,920 eggs in fish of 17.3 to 2.78 cm TL. Changes in food supply (Merryll, 1964) [22] or differences in natural mortality between the sexes (Ahmed and El Moghraby, 1984; Abdelha et al, 2020) [4,1] can cause the sex ratio to deviate from unity. In all six species, the study recognized five gonadal developmental stages, which agrees with Jones (1969) [17] and Alam (2000) [5] .…”

Biologi Reproduksi Rajungan Angin (Podophthalamus vigil) Di Selat Tiworo Bagian Barat, Konawe Selatan, Sulawesi Tenggara

“…Penelitian yang mengkaji tentang aspek biologi P. vigil masih sangat terbatas, diantaranya telah dilakukan oleh Subramaniam (2001) di perairan Tamil Naddu, India, Ikhwanuddin et al (2015) Data mengenai aspek biologi reproduksi seperti rasio jenis kelamin, tingkat kematangan gonad, fekunditas, ukuran pertama matang kelamin serta musim pemijahan perlu diketahui untuk dijadikan sebagai landasan dalam pengelolaan P. vigil yang berkelanjutan (Hamid, 2015;Hamid et al 2015;Ikhwanuddin et al 2015;Zairion et al 2015;Hamid, 2019;Hamid et al 2021) dan pendugaan stoknya (Abdelhak et al 2020). Ketersediaan data biologi reproduksi P. vigil di Indonesia sampai saat ini masih terbatas.…”
