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> Eri Iwata, Tasuku Yoshida, Tetsuya Abe, Kou Takahara, Koji Masuda Copyright (c) 2020 Journal of Fisheries Mon, 25 May 2020 10:00:01 +0000 Note on occurrence of Lutke’s halfbeak Hemiramphus lutkei Valenciennes, 1847 (Beloniformes: Hemiramphidae), along Odisha Coast <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> Swarup Ranjan Mohanty, Jaya Kishor Seth, Anil Mohapatra, Subhrendu Sekhar Mishra Copyright (c) 2020 Journal of Fisheries Sun, 24 May 2020 09:26:06 +0000 First records of sponge-dwelling shrimp Synalpheus coutierei Banner, 1953 (Crustacea: Decapoda) from the west coast of India <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> Barkha Purohit, Kauresh D.

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> Sezgi Arman, Sema İşisağ Üçüncü Copyright (c) 2020 Journal of Fisheries Sun, 17 May 2020 21:01:36 +0000 Prevalence of white spot virus and monodon baculovirus in shrimp culture systems of West Bengal, India <p>The global shrimp aquaculture is impacted by episodes of viral diseases resulting in huge income losses. This communication presents the results of the polymerase chain reaction (PCR) based surveillance of white spot virus (WSV) and monodon baculovirus (MBV) in shrimp culture systems of West Bengal, India. The WSV was detected in 14.87% of the total samples (<em>N</em> = 121) by first PCR and 16.53% of samples by nested PCR. The WSV infection was noticed in 12 of 65 <em>Penaeus monodon</em>, 6 of 39 <em>Litopenaeus vannamei</em> and 2 of 11 <em>Macrobrachium rosenbergii</em> samples. The MBV was detected in 8 of 65 <em>P. monodon</em> samples by non-nested PCR and all were also positive for WSV, thus indicating concurrent infection of shrimp. The results emphasized the need to observe strict quarantine measures during the seed selection to prevent the introduction of viral pathogens in grow-out systems.</p> Thangapalam Jawahar Abraham; Anjan Mondal, Avijit Patra, Harresh Adikesavalu Copyright (c) 2020 Journal of Fisheries Sun, 17 May 2020 08:31:15 +0000
