Age and growth of Mugil cephalus (Linnaeus, 1758) (Perciformes: Mugilidae) in Bonny Estuary

The age and growth of Mugil cephalus was investigated in Bonny Estuary, Nigeria, from January, 1995 to December, 1996. Length-weight relationships were isometric with length exponents of 2.84 (males), 2.90 (females) and 2.88 (overall). Modal length at age were 12.0cm, 20.9cm, 25.0cm, 28.4cm and 30.2cm TL for ages 0+, 1+, 2+, 3+ and 4+ respectively. Corresponding total weights were 20.01g, 78.93g, 173.12g, 217.61g and 247.50g, respectively. Asymptotic length (Lo) was estimated 33.2cm TL, asymptotic weight (W sub(o)) was 484g, growth coefficient K=0.55847 super(-1) and hypothetical age at zero length To = 0.152yr. Longevity, Tmax, was 5.0yr, length and weight growth performance indices were Q super(1)=2.79 and Q = 1.44, respectively. Total mortality, natural mortality and fishing mortality were z = 1.02yr super(-1), M=0.607yr super(-1) and F=O. 3129yr super(-1), respectively. The exploitation ratio E was 0.4048 and exploitation rate U = 0.2302yr super(-1

Raising Standards, Praising Tradition

While holding tight to our heritage through the traditional architectural design of the new building, we\u27re moving toward a new paradigm in the way lawyers are educated. The new School of Law will continue to embrace the Socratic Method, yet house computerized casebooks and dedicated networks and spaces devoted to today\u27s legal practices

“Always Ready for any Sticky Job”: The Canadian Corps of (Civilian) Firefighters in the Second World War

The Canadian Corps of (Civilian) Firefighters was created. In 1942 to assist the British National Fire Service (NFS) in fighting fires caused by German bombings. Some 400 specially-recruited Corps members served in Britain from 1942 to 1944 under often very hazardous conditions. Its story remains one of the forgotten and more unique Canadian contributions to the war effort
