We analysed histological characteristics of gonads and reproductive effort of the small deep-living dragonfishes Akarotaxis nudiceps (Waite) and Bathydraco marri Norman collected in the south-western Ross Sea. From a macroscopic point of view, most specimens of B. marri were juveniles in early stages of gonad maturity, except for a maturing female. Conversely, the sample of A. nudiceps was composed of both immature and adult fish in different stages of maturity. A single A. nudiceps female was…

Oocyte development and ovarian maturation of the black triggerfish, Melichthys niger(Actinopterygii: Balistidae) in São Pedro e São Paulo Archipelago, Brazil

The identification of five oocyte development stages in the ovarians from M. niger suggested that the specie follows a pattern similar to that described for other marine fish.

Biology of the Antarctic dragonfish Vomeridens infuscipinnis (Notothenioidei: Bathydraconidae)

Inferences from measurements of buoyancy and from morphological data suggest that Vomeridens lives in an epibenthic water column habitat at 400–900 m, and is likely to forage in the water column by hovering above the substrate.

Reproductive biology of estuarine catfish, Arius argyropleuron (Siluriformes: Ariidae) in the northern part of Peninsular Malaysia

A preliminary study on reproductive biology of estuarine catfish, Arius argyropleuron was conducted using samples collected from Merbok estuary which is located in the northern part of peninsular Malaysia, showing that the fish matured throughout the year.

Reproductive strategy of deep-sea and Antarctic octopods of the genera Graneledone, Adelieledone and Muusoctopus (Mollusca: Cephalopoda)

It is demonstrated that the size distribu- tion of post-ovulatory follicles (POF) is mostly unimodal, suggesting that they only lay 1 batch of eggs, and that deep-sea and polar benthic octopods are generally not multiple spawners.

Life history traits of rare Antarctic dragonfishes from the Weddell Sea

Abstract The life history traits of bathydraconids, deep-living fishes distributed all around the Antarctic continent, are poorly known. In particular, very few data are available on the relatively…

First case of possible iteroparity among coleoid cephalopods: the giant warty squid Kondakovia longimana

The capture of a large female of the giant warty squid Kondakovia longimana Filippova, 1972 questions this established point of view and restricts the possibility of iteroparity to those few cephalopods that live for many years.

Histological and ultrastructural study of Zona Radiata in oocyte of common carp Cyprinus carpio (Linnaeus 1758).

Morphological and histological studies on the ovaries of the small-scaled terapon, Terapon puta, from Lake Timsah, Ismailia governorate, Egypt -

The morphological studies of T. puta indicate that the maturity stages of the ovaries could be divided into three stages, namely: the pre- spawning, the spawning and the post-spawning stages.

Reproductive Performance of Carica papaya, Hibiscus rosa-sinensis and Ipomoea batatas on Female African Catfish (Clarias gariepinus)

The findings of this study suggest that C. papaya seeds, hibiscus leaves and sweet potato leaves have the potential to impair reproductive performance in female African catfish and holistic measures should always be taken when using these plants considering the effect it could exert on other aquatic inhabitants and systems.

Light and electron microscope structural study of the zona radiata in the oocyte of zebrafish (Danio rerio).

The zona radiata (ZR) is a non- cellular envelope over oolemma of teleost fish oocytes that varies in different ovarian developmental stages and also among various fish species, which reflects adaptation to ecological conditions.

Gametogenesis in the Antarctic plunderfishes Artedidraco lönnbergi and Artedidraco skottsbergi (Pisces: Artedidraconidae) from the Ross Sea

First data on the reproductive characteristics of these two plunderfishes are presented, including gametogenesis, spawning period and absolute fecundity, which are compared with those reported in literature for other artedidraconids.

Reproductive biology of the icefish Champsocephalus esox (Günther, 1861) (Channichthyidae)

In C. esox, relative fecundity has a similar range to those quoted for the different C. gunnari populations, Whilst mature oocyte diameter is small and reproductive season extended compared to the same parameters in other Channichthyidae, a transfer of matter from liver to the gonads is suggested.

Features of gametogenesis and sexual cycles of six notothenioid fishes from East Antarctica

Among the features of gametogenesis of icefishes are the early accumulation of yolk in oocytes, and the beginning of polarization and homogenization of yocytes, which are far from definitive sizes.

Reproductive biology of female Antarctic spiny plunderfish Harpagifer spinosus (Notothenioidei: Harpagiferidae), from Îles Crozet

The data indicate that the features of the reproductive biology of H. spinosus, in spite of its unusual environment, are similar to those observed in other teleost fish.

Macroscopic and histological analyses of gonads during the spawning season of Chionodraco hamatus (Pisces, Channichthyidae) off Terra Nova Bay, Ross Sea, Southern Ocean

The present data confirm that C. hamatus, as is typical for Antarctic fish, probably spawns a single batch of oocytes once a year, and vitellogenesis is a slow process that extends over at least 1 year.

Oocyte development and maturity classification of Gerlachea australis from the Weddell Sea, Antarctica

The features of oogenesis and ovarian maturation in G. australis are similar to those described for other teleosts.

Reproduction in Antarctic notothenioid fish

A number of reproductive strategies associated with nest guarding, egg size and the duration of the pelagic phase have been identified and there is a general trend in nototheniids of increasing egg sizes and decreasing relative fecundity towards higher latitudes.

Spawning behaviour and early development in the naked dragonfish Gymnodraco acuticeps

Nesting sites of the naked dragonfish Gymnodraco acuticeps have been identified in 15–35 m water under fast ice adjacent to McMurdo Station, making it possible to examine embryonic development and…

Spermatogenesis in some Antarctic teleosts from the Ross Sea: histological organisation of the testis and localisation of bFGF

Testis structure and spermatogenetic activity were studied in two Antarctic teleostean species, Chionodraco hamatus and Trematomus bernacchii, captured during the austral summer in the Ross Sea, to indicate that Antarctic fish have an opportunistic sperMatogenetic cycle.

Reproduction in fish of the Weddell Sea

Reproductive characteristics of 28 fish species were obtained during EPOS leg 3 in the inner Weddell Sea The gonadosomatic index (GSI) of female notothenioid fish was 15–30% at spawning. GSI in males…
