• As a consequence of these factors, those hobbyists for whom the fish hobby represents a challenge and for whom a large part of their time is occupied with fishkeeping, form bonds with others of similar tastes. Thus are born societies (many of which struggle for years because of casual, essentially disinterested members) and correspondence fra- ternities. In the case of killifish fanciers, the latter associations inevitably lead to attempts to exchange species by the only means available, i.e., postal or express carriers. Since eggs generally are more readily avail- able than fishes as far as aquarists are concerned, most exchanges in- volve the shipment of eggs. However, the shipment of live fishes from hobbyist to hobbyist is becoming more popular day by day. As for eggs, many techniques have been developed for shipping them. They all share three attributes consistent with reasonable success: the eggs must be viable; they must be protected from the vagaries of the weather likely to be encountered along the way; and they should be shipped with minimum weight to reduce costs. Our first look into shipping procedures and techniques then, is con- cerned with eggs. ll. EGG EXCHANGES The cardinal rule is that eggs that are to be shipped must be fertile eggs. In order to insure this, the aquarist should examine each and every egg individually or else send a large enough quantity so that infertile eggs are offset in numbers by fertile ones. If eggs are not examined prior to shipment, there is the danger of infertile eggs becom- ing fungused, the fungus spores then getting onto fertile eggs where they grow and destroy the incipient embryos. It is preferable that eggs to be shipped be all approximately of the same age, also. In the case of plant breeders such as Aphyosemion australe, A. bivittatum, Epiplatys chaperi, Rivulus cylindraceous, etc., mops in which the fish have spawned should be removed from the water, gently squeezed to remove excess moisture and gone over strand by strand to remove the eggs. A flat container, such as a photographic tray (which has never been used for photographic purposes) in which there is about one inch of clean water of the same pH and DH as the tank in which the breeders are, is used to receive the eggs. Eggs are picked off the mop either with the fingers or with clean tweezers (see figures 1 and
