Figures 7-12. — Histological comparisons of healthy (left) and emaciated (right) northern anchovy larvae. — Continued. 7) The trunk 

 muscles cut in cross section above and below the notochord are compact. The foregut and midgut have mucosa of good thickness and 

 integrity. 5.5 mm SL; 100 x . 8) Trunk muscles are separated and uneven, the midgut is filled with disassociated cellular material, and the 

 pancreas is severely disassociated. 5.5 mm SL; 100 x. 9) Portions of the midgut, the pancresis, and the trunk musculature below the 

 notochord all show good integrity. 5.0 mm SL; 250 x. 10) Enlargement of Figure 8 for comparison of pancreas to that in Figure 9. 

 250 X . 11) The foregut is regular and the trunk muscles are compact. The foregut is not yet expanded, and the midgut is not visible in the 

 section. The remnant of the yolk sac, primarily periblast tissue, is prominent. 2;5 mm SL; 250 x . 12) The midgut is a solid mass of necrotic 

 debris. The notochord and trunk muscles are collapsed and irregular. The kidney is necrotic. 2.2 mm SL; 250 x . Symbols: Fg, foregut; K, 

 kidney; L, liver; M, trimk muscle; Mg, midgut; N, notochord; P, pancreas; S, spinal cord; U, mucosa; Y, yolk. 



muscle deterioration observed in the northern an- 

 chovy larva. It is essentially a phenomenon of 

 protracted struggle in large animals. In the case of 



478 



the northern anchovy larvae, time and physical 

 manipulation were minimized in capture.
