Spawning season

Therefore, it is necessary to study the spawning season as a basis for artificial spawning, developing seed production technology and subsequently providing this species to the aquaculture industry. Together, this help contributes to diversifying culture species, maintaining, developing resources, protecting genetic resources, and conserving biodiversity in the Central region and the entire country in general.

In order to provide reliable indicators of the spawning season of captive helicopter catfish (Wallago attu), this study evaluated the temporal variation in gonadosomatic index (GSI), plasma levels of testosterone (T), and 11-ketotestosterone (11-KT) in male broodstock in captivity.

The Tibetan highland fish, Gymnocypris przewalskii, migrates from Lake Qinghai to its spawning grounds every summer. This seasonal reproduction is critically regulated by intrinsic and extrinsic signals. However, the molecular mechanisms that process environmental oscillations to initiate the seasonal mating are largely unknown.

Pleurotus mushroom, generally referred to as ‘Oyster mushroom or Dhingri’ in India is relatively new to the mushroom industry. In India, Odisha is a leading state in terms of oyster mushroom production. The condition in most of agro-climatic situation in Odisha are suitable for growing oyster mushroom from month of July to February comprising of the rainy and winter season. Pleurotus pulmonarius is a potential protein source especially in developing countries, besides having minerals and vitamins. Besides its edibility it has also got pharmaceutical properties.

Three species of Oyster mushroom like, Pleurotus ostreatus, Pleurotus sajor-caju, Pleurotus florida mother culture were procured from DMR, Solan and wild collected strain was collected from Bankura district in West Bengal during the monsoon season of 2017- 18. The experimental fruiting trials were conducted under the mushroom house conditions using three substrates viz. Paddy straw, Paddy straw + Sugarcane bagasse (1:1) and Sugarcane bagaase to observe variation in spawn run days, pinning initiation and biological efficiency.

In the present study, the Gonadosomatic index and Hepatosomatic index of common carp (Cyprinus carpio var. communis) broodstock was evaluated. Both sexes of two different age groups (virgin and 1+ year) were selected for the study. It was observed that all the physico-chemical conditions were optimum. The GSI and HSI values were maximum during March which is supposed to be the spawning season of common carp in India.

Performance of milky mushroom (Calocybe indica) on different agricultural wastes like paddy straw, castor stalks, sunflower stalks, coconut coir pith, oil palm waste and groundnut shells was evaluated during the summer season. The spawning was done by sterilization of all the seven substrates. The bags were kept in spawn running room with the maintenance of temperature (30°C–35° C) and relative humidity (70–80 %) respectively.

The ob jective of this paper is to study the economic management of Eastern Baltic cod (Gadus morhua) under the influence of nutrient enrichment. Average nitrogen concentration in the spawning areas during the spawning season of cod stock is chosen to be an indicator of nutrient enrichment.

The experiments were implemented during the spawning season from April to October 2007 in Nha Trang, Khanh Hoa under laboratory conditions. There were no significant differences of embryo development time when eggs were incubated at salinity of 20 ppt and 30 ppt. The salinity of 10 ppt was not suitable for embryo development. The surival rate of 3 - day larvae at 30 ppt group was higher than that of 20 ppt group.

The Mekong River system supports one of the world’s largest and most diverse inland fisheries. It includes a broad assortment of operations, ranging from solitary fishers to largescale commercial enterprises. The catch contains a high proportion of fishes whose lifecycles involve migrations between feeding and spawning grounds and dry season refuges. The preservation of the river’s fisheries, therefore, partly depends on keeping the migration routes these fish use free from obstructions and barriers that could critically disrupt their lifecycles.
