De zuidwestsectie van het Internationale Regenboogvisgezelschap nam samen met JBL het initiatief een kleine zaterdagmiddagexpeditie te organiseren naar verschillende gebieden aan de Rijnland-Palts-zijde van de Rijn waar het vangen van voederdieren conform de landelijke visserijwet (§31) niet gekoppeld is aan een visvergunning.

Il gruppo sud-est dell'"Associazione internazionale pesci arcobaleno" organizzò, assieme alla JBL, una piccola spedizione, un sabato pomeriggio, a diversi fondali di pesca. Questi si trovano sul lato del reno che appartiene al Palatinato perché qui la cattura di cibo vivo non richiede una licenza di pesca (§31 Legge regionale sulla pesca). Oltre a grandi quantità di larve di zanzare nere e a poche larve di zanzare bianche sono stati catturati molti pulci d'acqua e Cyclops con le reti JBL. In una foresta sommersa furono trovate poi le rare artemie d'acqua dolce! Con l'aiuto del test dell'acqua JBL ProScan determinammo i valori dell'acqua direttamente sul posto: non erano rilevabili nitrito e nitrato benché ci fossero grandi quantità di foglie nell'acqua. La durezza totale e quella carbonatica erano di 4 °dH e il pH di 6,8. I Cyclops grandi circa 2 cm erano così carini che a casa non furono usati come pasto, cosa che avvenne invece per le larve di zanzare, ma vennero allevati in un piccolo acquario. Con un po' di mangime liquido a base di alghe, JBL Artemio, la cura risulta facile.

The south west group of the International Rainbow Fish Association and JBL initiated a little Saturday afternoon expedition to the various fishing grounds on the Rhineland-Palatinate side of the Rhine, since catching feeder animals there is, according to the provincial law on fisheries (§31), not dependant on having a fishing license. Along with large amounts of black and a few white mosquito larvae a lot of water fleas and cyclops were caught in the JBL nets. Then, in a flooded forest, we found our rare freshwater artemia! With the help of the JBL ProScan water tests the water values were determined immediately on-site: nitrite and nitrate were undetectable, although enormous amounts of leaves were present! General hardness and carbonate hardness were at 4 °dH with a pH value of 6.8. The about 2 cm large Branchiopoda were so cute that we don’t plan to feed them to the aquarium fish, as we will with the mosquito larvae. Instead we’ll keep them in a small aquarium. With a bit of liquid algae food looking after them will be easy.
