TLDR
A pure-cone retina has been reported in the larval stages of teleosts from three families, viz. the salmon Oncorhynchus spp, the herring Clupea harengus and plaice Pleuronectes platessa.Abstract:
A pure-cone retina has been reported in the larval stages of teleosts from three families, viz. the salmon Oncorhynchus spp. by Ali (1959), the herring Clupea harengus by Blaxter & Jones (1967) and plaice Pleuronectes platessa by Blaxter (1968 a). There is also an absence of any retinomotor responses (movement of retinal masking pigment and changes in the relative positions of the visual cells) until the rods develop, which is usually at metamorphosis where this is clear-cut. Most adult teleosts are known to have a duplex retina.read more

TL;DR: The conductivity bridge derives its bridge source from a self-contained vacuum tube oscillator adjusted to approximately 1,000 cycles as mentioned in this paper, which operates directly from the A.C. power source.

TL;DR: The findings demonstrate that rods and cones are developmentally distinct cell types in the mouse retina.
Roles of behavioral and physical factors in larval and juvenile fish recruitment to estuarine nursery areas
TL;DR: This work considers recruitment to the estuary of species spawned offshore as a two-stage process dependent first upon factors in the offshore planktonic environment and second upon estuarine factors related to tidal flux, and suggests that the suite of factors associated with tidal flux at particular locations may act as the zeitgeber for an endogenous rhythm with a tidal periodicity.

The ocular structure, retinomotor and photo-behavioral responses of juvenile pacific salmon
TL;DR: From a histophysiological study it is evident that only the emerged fry and older stages are capable of retinomotor responses and that these responses become more marked with age.
