FACTORS THAT CAN LEAD TO THE DEVELOPMENT OF SKELETAL DEFORMITIES IN FISHES: A REVIEW
Skeletal deformities can significantly reduce hatchery production and impact the production cost. Some of these include kyphosis and lordosis as well as jaw malformations, kyphosis and kyphosis. It is not known what causes skeletal deformities in fishes. These deformities may be caused by many factors. This article will focus on the most important of these…
Characterization by microphotography of larval and prejuvenile stage of discus fish (Symphysodon spp.)
This study examined the morphological growth of the larvae from discus fish (Symphysodon species). The development of the larvae in laboratory conditions was monitored from their hatching day to the 32nd day. Three pairs of broodstock were used to produce the larvae. They were kept in 60L glass aquaria. All larvae were taken from one…

Wound ballistics: analysis of blunt and penetrating trauma mechanisms
Background: The tissue factors that are important in wound ballistics offer valuable insight into the pathophysiology and severity of all types of trauma. Wound ballistics can be used to identify blunt and penetrating trauma mechanisms. The mechanism of tissue injury can be combined, even though it may be either blunt trauma or pure blunt trauma.…
