Tenualosa ilisha (Hamilton) is a valuable migratory fish belonging to the family Clupeidae and it is distributed in a wide area from the Persian Gulf to coasts of Pakistan and China’s southern sea. The aim of the present study was to investigate the changes occurring in innate immunity parameters during upstream migration and comparing them to those during post spawning. Sixty mature female hil...

The purpose of this study was to explore the feeding habits and preference prey of Sphyraena jello in Chabahar marine waters between April 2019 to March 2020. The number of 385 specimens with mean (±SD) total length and weight 64.0±3.5 cm and 925.45±12.0 g for males and 66.0±2.45 cm and 1001.35±5.2 g for females were examined. Length-weight relationships of male and female was respectively comp...

The wetland acts as a natural reproduction and rehabilitation ground for several groups the Caspian Sea fishes. It also serves as a habitat and spawning ground for the Caspian Sea migratory fish ...
C over the production of highly fecund species such as Pacific herring (Clupea pallasii) has been attributed historically to bottom-up effects such as ocean conditions or food availability. In contrast, top-down control exists when predation limits population production. Recent observations of humpback whales (Megaptera novaeangliae) foraging on depressed herring populations suggests top-down c...
