| ຂໍ້ສັງເກດ | Life stages of the species collected (fish larvae and juveniles). Fish larvae were caught with a bongo net (60 cm in diameter, with 0.5 mm mesh size on the outer net and 0.335 mm on the inner net). At each of the 57 stations, 2 oblique hauls at a speed of 3 knots were carried out up to 2 m above the bottom. The samples were fixed on board in 4% formaldehyde. 'Flow-through counter' measurements made possible the calculation of fish volumes. | ||
