摘要

大规模生产鱼种是石斑鱼水产养殖发展面临的最大挑战之一。石斑鱼可能更容易骨骼异常，由于其复杂的骨骼形成个体发生。这种异常通常与不充分的海鱼幼体养殖方案有关。本研究旨在记录黑石斑鱼(Epinephelus marginatus)骨骼异常的发生。不同程度的后凸、前凸和脊柱侧凸被确定。经过60天的幼虫期，42%的黑石斑鱼出现骨骼异常。因此，我们得出结论，必须重新审查目前的黑石斑鱼幼虫养殖方案，特别是确定更合适的水箱水量。

Skeletal anomalies in dusky grouper Epinephelus marginatus larviculture

The production of fingerlings on a large scale is one of the biggest challenges for grouper aquaculture development. Groupers may be more susceptible to skeletal anomalies due to their complex skeleton formation ontogenesis. Such anomalies are normally associated with inadequate larviculture protocols for marine fish. The present study aimed to record the occurrence of skeletal anomalies in dusky grouper Epinephelus marginatus. Different degrees of kyphosis, lordosis, and scoliosis were identified. After the larviculture period (60 days), 42% of the dusky grouper presented skeletal anomalies. Therefore, we have concluded that the current protocol for the dusky grouper larviculture must be re-examined, especially to determine a more appropriate water flow in the tanks.

期刊介绍： Latin American Journal of Aquatic Research- LAJAR is the continuation of the journal Investigaciones Marinas (1970-2007) and is published since 2008 by the Escuela de Ciencias del Mar, Facultad de Ciencias del Mar y Geografía of the Pontificia Universidad Católica de Valparaíso. LAJAR is an “Open Access” journal that publishes in English language, original research articles, reviews and short communications on aquatic science, which contain the results of research conducted in aquaculture or in oceanic and coastal marine waters of Latin America. The following topics are considered: Physical Oceanography, Chemical Oceanography, Marine Biogeochemistry, Marine Pollution and Toxicology, Marine Geology and Geophysics, Biological Oceanography, Fisheries and Aquaculture.
