Zootechnical parameters and hepatosomatic index of two genetic strains of Nile tilapia fed with β-Glucan + Mannan oligosaccharide (βG+MOS)

Semina: Ciências Agrárias
The increasing expansion and the rising demand for food require a greater intensification in the production of Nile tilapia (Oreochromis niloticus), and genetic improvement programs are essential to achieve this goal. In managing these programs, new genetic material is introduced after several generations of selections to reduce inbreeding and enhance ...

Effectiveness of Soybean Meal as a Feed Supplement on Gonadal Maturation, Gonadosomatic Index (GSI), Hepatosomatic Index (HSI), and Spawning Success of Female Broodstock Catfish

Nekton
The increasing demand for catfish (Clarias sp.) consumption necessitates a sustainable supply of broodstock and seed for aquaculture. One of the main constraints in meeting this demand is the low gonadal maturation rate of catfish outside the natural spawning season. Reproductive hormones play a central role in regulating gonadal maturation through the

Microplastic contamination in the endemic Fiji maskray (Neotrygon romeoi)

Frontiers in Marine Science
Plastic waste accumulates in coastal environments, posing risks to marine organisms and the human communities that depend on them. Fiji relies heavily on inshore fisheries, yet the extent and physiological implications of microplastic (MP) contamination ...

Determination of the spawning time and changes in the reproduction cycle of ribbon fish, Trichiurus lepturus, according to the hepatosomatic index and gonadosomatic index

, 1997
The ribbon fishes, belonging to the family Trichiuridae, are one of the most important protein resources in the Indian Ocean. A considerable density of the dominant species of this family, Trichiurus lepturus has been observed in the Oman Sea. During the conducted cruises in the northern part of the Oman Sea, gonadosomatic index (GSI) and hepatosomatic
