The specimens (<em>N</em> = 125) were caught using the gill nets in the Sorgun Dam (Aksu, Isparta). The age of the study specimens varied between one and six years. The total length and body weight of the specimens varied from 17.7 – 36.7 cm and 57.03 – 526.91 g respectively. A negative allometric growth (<em>b</em> = 2.7743) was recorded for the species whereas the LWR and total length (TL) – fork length (FL) equations were <em>W</em> = 0.0203 × TL<sup>2.7743</sup> (<em>R<sup>2</sup></em> = 0.95) and <em>TL</em> = 0.402 + <em>FL</em> × 1.061 (<em>R<sup>2</sup></em> = 0.99) respectively. The condition factor was determined for every specimen. In light of the results obtained in the study this species may be considered for aquaculture ensuring sustainable population in the wild. This study provides new information that can play an important role in the sustainable management this species.</p> 2020-05-26T13:00:40+00:00 Copyright (c) 2020 Journal of Fisheries Behavioural differences between breeding and nonbreeding pairs of protandry monogamous false clown anemonefish Amphiprion ocellaris 2020-05-25T10:00:03+00:00 Eri Iwata Tasuku Yoshida Tetsuya Abe Kou Takahara Koji Masuda <p>Anemonefishes are some of the most popular marine ornamental fishes. Due to the adverse impacts of commercial fishing on the wild populations of anemonefishes, a more suitable and efficient captive breeding programme must be promoted. In the wild, anemonefishes are protandrous sex-changing fish, but when two immature individuals with ambisexual gonads are raised together in captivity, the two differentiate directly into a male and a female, to form a breeding pair. However, not all the formed pairs spawn, explaining the great care required in captive breeding. This behaviour appears to be counter-adaptative, as anemonefish social groups form randomly in the wild, and such phenomenon would disturb their breeding success. This study evaluated the behavioural and physiological differences between breeding and nonbreeding pairs of false clown anemonefish <em>Amphiprion ocellaris</em> under captive conditions. Behavioural observations revealed that nonbreeding females monopolized the shelter provided, whereas breeding females allowed breeding males to use the shelter and the pair frequently stayed together in the shelter. Both nonbreeding and breeding females possessed mature ovarian tissue and similar level of plasma estradiol concentrations, but nonbreeding males had a smaller amount of testicular tissue and lower plasma 11-ketotestosterone levels compared to breeding males.</p> 2020-05-25T10:00:01+00:00 Copyright (c) 2020 Journal of Fisheries Note on occurrence of Lutke’s halfbeak Hemiramphus lutkei Valenciennes, 1847 (Beloniformes: Hemiramphidae), along Odisha Coast 2020-05-24T13:58:18+00:00 Swarup Ranjan Mohanty Jaya Kishor Seth Anil Mohapatra Subhrendu Sekhar Mishra <p>The paper reports occurrence of Lutke’s halfbeak <em>Hemiramphus lutkei</em> Valenciennes, 1847, for the first time from the coastal waters of Odisha coast, India. This report confirms the occurrence of this species form an extended geographical range along the east coast of India and will be helpful in further study of its biology, zoogeography and taxonomic status of the family Hemiramphidae.</p> 2020-05-24T09:26:06+00:00 Copyright (c) 2020 Journal of Fisheries First records of sponge-dwelling shrimp Synalpheus coutierei Banner, 1953 (Crustacea: Decapoda) from the west coast of India 2020-05-21T11:36:42+00:00 Barkha Purohit Kauresh D. Vachhrajani <p>The occurrence of the two pairs of mature sponge dwelling shrimp <em>Synalpheus coutierei</em> Banner, 1953 is reported first time from the west coast in Gujarat, India. This species is previously reported from the east coast of India. The detailed morphological characteristic and distribution of the species are given in the paper.</p> 2020-05-20T13:15:18+00:00 Copyright (c) 2020 Journal of Fisheries Gonadal histology of the tiger barb Puntius tetrazona (Cyprinidae) 2020-05-18T11:32:51+00:00 Sezgi Arman Sema İşisağ Üçüncü <p>The ornamental fish industry constitutes a big portion of the economy in many countries of the world. Thousands of attractive fish species are traded annually. The tiger barb <em>Puntius tetrazona</em> is one of the most charming freshwater aquarium species worldwide. The present paper aimed at expanding the knowledge of the reproductive biology of this tropical fish. The ovary and the testis tissues of the tiger barb were embedded in paraffin following routine histological processes, stained with hematoxylin and eosin and Mallory’s trichrome techniques, and investigated by light microscopy. Histological examinations confirmed asynchronous-type ovaries resembling four different developmental stages including primary growth, cortical alveolar, vitellogenic and maturation. In the testis, primary spermatogonia, secondary spermatogonia, primary spermatocytes, secondary spermatocytes, spermatids and spermatozoa were identified. All oogenetic and spermatogenetic phases and mature germ cells occurred simultaneously in the tiger barb. This feature allows this tropical fish to breed rapidly and helps expanding its global trades.</p> 2020-05-17T21:01:36+00:00 Copyright (c) 2020 Journal of Fisheries
