This study investigated the reproductive cycle of edible oyster, Crassostrea belcheri, harvested originally from creeks near Pedaing village in southern part Myanmar September 2017-October 2018 through histological analysis. Five maturity stages were detected C. belcheri gonads: indifferent, developing, mature, spawning, and spent. The overall sex ratio males to females 1:0.98 showed no statist...

We report the proteomic dataset of gonads from wild Paracentrotus lividus related to the research article entitled "Proteomic changes occurring along gonad maturation in the edible sea urchin Paracentrotus lividus" [1]. Gonads of three individuals per sex in the recovery, pre-mature, mature, and spent stages were analyzed using a shotgun proteomics approach based on filter-aided sample preparat...

We searched for correlations between water level, rainfall, temperature, and reproductive activity of fishes in a lotic stretch of the Grande River below the Volta Grande Dam. Gillnets were used to catch the fish on six field journeys made bimonthly between April 1998 and February 1999. Fish gonads were classified according to maturation grade and the amount of mature or spent gonads was correl...

The study was aimed at analysing body size in relation to form of gonad maturation (amount of mature germ cells) in 329 under-yearling sea trout males. The fish, aged 7 months, were caught in late October-early November in 3 streams located in north-western Poland. Each stream supported fish belonging to a different sib group. Standard histological techniques and a computer image analysis progr...

Yolk sac tumour is germ cell tumour commonly found in children and infants under three years of age in its pure form with a good prognosis. The commonest location for the yolk sac tumour is gonads i.e. testis and gonads. Yolk sac tumour is rarely reported in extra- gonadal locations. Parapharyngeal space is an uncommon site for mature teratoma and very few cases have been reported in adults and...

Maturity was studied on 273 rainbow trout of both sexes. The female gonads were classed into 3 maturation stages and the male gonads into 4. Characteristic pherograms of both serum protein electrophoresis and total serum protein corresponded with maturation stage. Electrophoretic globulin and total protein fractions increased considerably with spermatogenetically active testes and mature ovarie...

Acaudina rosettis is one of the commercial sea cucumber species that widely consumed on east coast Surabaya, East Java, Indonesia. Although its abundance in nature has begun to show signs decreasing, studies this are still very limited. This study aimed examine indicators can be used determine sex A. individuals. samples were collected from Madura strait mid Hijri month for three months. The th...

we performed a plankton survey of blood cockle larvae, anadara spp., and histological observations of the gonads of adult blood cockle, anadara granosa , in the coastal waters off sungai buloh, peninsular malaysia from october 2010 to april 2011. the histological observations indicated the main spawning period in both sexes was from november to march. in addition, the occurrence of blood cockle...
