Fish Population Dynamic and Stock Assessment (2+1)

Problem : 2

Estimate the growth parameters, K and $$L_\infty$$ using Gulland and Holt plot

Sl.No.	t	L(t)
1.	0.64	17.3
2.	1.16	27.9
3.	1.65	25.3
4.	2.10	40.2
5.	2.64	43.3
6.	3.21	45.5

1. Calculate $$\Delta t$$
2. Calculate $$\Delta L(t)$$
3. Calculate $${\Delta L(t) \over \Delta t}$$
4. Calculate mean growth rate.
