Streptococcus agalactiae Infection in Nile Tilapia (Oreochromis niloticus): A Review

Biology
Simple Summary Streptococcus agalactiae, a significant pathogen affecting humans and aquatic species, is causing high morbidity and mortality in fish, particularly Nile tilapia (Oreochromis niloticus). This study focuses on S.

Testosterone nanoemulsion produced masculinized Nile tilapia (Oreochromis niloticus)

Fish Physiology and Biochemistry, 2022
The objective of this work was to develop a food additive for the sex reversal of Nile tilapia (Oreochromis niloticus) based on a simple oil in water (O/W) nanoemulsion with testosterone propionate for incorporation into commercial feed. Oil screening and evaluation of the organoleptic and physicochemical characteristics were carried out to determine ...

Energy metabolism in Oreochromis niloticus

Aquaculture, 1989
A series of experiments was carried out to study the energy metabolism of Oreochromis niloticus. During starvation the energy loss of the fish was 25 kJ kg−0.8 d−1 (54 kJ kg−1 d−1). Maintenance requirement for energy amounted to 57 kJ ME kg−0.8 d−1 (116 kJ ME kg−1 d−1). Apparent utilization of metabolizable energy (ME) below maintenance requirement was

ผลของน้ำโอโซนและการบรรจุแบบสุญญากาศต่อการเจริญของแบคทีเรียก่อโรคและแบคทีเรียที่ทำให้เสื่อมเสียบางชนิดในปลานิล Oreochromis niloticus แล่

2023
งานวิจัยนี้มีวัตถุประสงค์เพื่อศึกษาการใช้โอโซนในรูปของสารละลายต่ออายุการเก็บรักษาปลานิลแล่แช่เย็นที่บรรจุในบรรยากาศปกติและสุญญากาศ ติดตามคุณภาพทางจุลินทรีย์ และกายภาพเคมี โดยศึกษาการใช้น้ำโอโซนที่ระดับความเข้มข้นต่าง ๆ (0-2 ppm) สำหรับทำความสะอาดปลานิลแล่ด้วยวิธีการแช่ และใช้สารละลายโซเดียมไฮโปคลอไรท์ 10 ppm ทำความสะอาดเป็นตัวอย่างควบคุม พบว่าจำนวนจุล ...

Gene transfer in tilapia (Oreochromis niloticus)

Aquaculture, 1988
Abstract The microinjection of the human growth hormone gene into the germinal disc and the development of 90-day live transgenic tilapia are reported. Three different spawns, treated 10 min, 21–24 h or 40–43 h after spawning, were used. For microinjection a linear 4.0 kb EcoRI-DNA fragment containing the mouse metallothionein-I promoter (mMT-I ...

Nile Tilapia Oreochromis niloticus (L.)

2017
Nile tilapia Oreochromis niloticus (L.) is one of the most widely cultured and most widespread invasive fish species globally. It was the most common alien fish species in South China where it has successfully established populations in the major rivers, and became the dominant species in many sites.

Mercury exposure in the freshwater tilapia Oreochromis niloticus

Environmental Pollution, 2010
Mercury (Hg) can be strongly accumulated and biomagnified along aquatic food chain, but the exposure pathway remains little studied. In this study, we quantified the uptake and elimination of both inorganic mercury [as Hg(II)] and methylmercury (as MeHg) in an important farmed freshwater fish, the tilapia Oreochromis niloticus, using (203)Hg ...
