An attempt was made to provide some vital aspects of reproductive biology of cobia Rachycentron canadum (Linnaeus, 1766). Samples for a period of two years from an exploratory vessel and from the landing centers of Mumbai were used for the study. The average sex ratio between males and females observed was 1:0.80. Dominance of the number of females above the size of 100 cm was noticed. The size...

The black sea urchin (Arbacia lixula, Linnaeus, 1758) is a non-edible marine echinoderm of high ecological importance with the potential to affect communities. A. lixula were sampled monthly for one year from supralittoral fringe at two locations in Pagasitikos Gulf, north-western Aegean Sea. Morphometric characteristics exhibited significant spatiotemporal variation. population closer proximit...

A total of 1,364 specimens of Sepia officinalis (Lineaus, 1758), including 643 females and 532 males were measured from February 2010 to January 2011 catching by the commercial trawling fisheries of Algiers region. The sex, dorsal mantle, wet body mass, nidamental gland weight and female gonadal weight were recorded. The mean length of the dorsal mantle for females was 11.68±0.03 cm and for mal...

Objective: The first aim of this study is to describe the length, weight, condition factor, and GSI Alburnus istanbulensis (Battalgil, 1941) in two different connected habitats (stream habitat reservoir lake) Karamenderes River, Çanakkale. second state growth type species sampled using length-weight relationship (LWR) model. Materials Methods: sampling areas are Bayramiç Reservoir tributaries o...

The management of invasive Blue Catfish Ictalurus furcatus in Chesapeake Bay tributaries is hindered by the lack information on its reproductive biology, which a key component population models used to forecast abundance. We quantified and compared traits female from two populations tidal reaches James York River subestuaries during 2015–2017. In these systems, matured between ages 6 10 years s...

Abstract The study deals with the growth pattern, mortality, and reproduction of common sole, Solea solea (Linneaus, 1758), from Sea Marmara (Turkey). A total 580 fish specimens were sampled monthly October 2017 to September 2018. length all individuals ranged 11.1 29.5 cm, corresponding ages 1 3 years. length–weight relationship was expressed as W = 0.022 TL 2.6838 , where slope indicated nega...

Climbing perch called Papuyu fish in South Kalimantan Indonesia caught swamp waters, is a that very popular with the community and has high economic value. Fish reproductive performance important to obtain information on natural conditions of status climbing form gonadal maturity level, fecundity. This research aims analyze based level maturity, index fecundity ( Anabas testudineus Bloch). The ...

Developing a robust understanding of Pacific halibut reproductive biology is essential to the different components (e.g. maturity) that determine output species and, therefore, for estimating relative female spawning biomass. With these, effective and proactive management strategies can be designed implemented face large-scale environmental changes which high-latitude fish are particularly vuln...

Fish reproductive biology plays an important role for fishery management, especially in developing countries. The aim of this study was to compile all available information and analyze reproduction patterns of marine fishes in three Large Marine Ecosystems (LMEs): North, East, and South Brazil Shelves. We tested the hypothesis that the onset and duration of spawning season differ among these th...
