chungsl Posted December 26, 2005 Share Posted December 26, 2005 i try to collect wild copepods by a small plankton net(only wave it in water by two hands), want to know the degree of usefulness of the small net and the abundance of copepod in particular location in winter. date & time: 26/12/05, 14:00, sunny day location: a mangrove beach water temp: 20 degree C(winter) water depth: 2 feet tides : rising i use florida Farm 50 micron plankton net (5"dia,15"long)with a 2m long rod, wave it by hands slowly on the surfuce of water for 15 mins ,mix the collected bottle's water up to 1L seawater. i roughly count the amount and type of copepod in this collection: 1) 2-3 /ml (nauplii of copepods,i only guess it is nauplii)=90% 2) 0.2-0.3/ml ( adult of copepods or one is bigger than nauplii )=10% 3) total collect about 3,000 pcs copepods below pics are in same magnification,the rotifers are s-rotifer(110-140 micron). the two nauplii below the rotifers. just for fun in holiday! any bro. has experience in collecting wild copepods for sharing .

SRC Member iantoh Posted December 26, 2005 SRC Member Share Posted December 26, 2005 hi there bro chungsl, whereabouts did you go plankton netting? thats cool. perhaps you could share with us more. what have your capture rates been for rotifers versus copepod naupliis? theoretically, to catch copepods, youd have to go at night? if youre doing this in singapore perhaps i could tompang? cheers, ian Quote My Goniopora Nano!

keithtanbb Posted December 27, 2005 Share Posted December 27, 2005 Good job! applause for the effort.maybe you can culture them, same methods as for rotifers, use baker yeast to feed (economical) and dose with phythoplanktons before harvest! Been doing this with my LFS -bought rotifers, (got to make sure they have enough food to eat or the culture will crash! Quote Link to comment Share on other sites More sharing options...

chungsl Posted December 27, 2005 Author Share Posted December 27, 2005 FuEl, do you culture copepods? what's type ? iantoh, the mentioned mangrove is in H.K. i have saw the whole bench has numerous carb in low tide,i think the larval carb need enough amount of copepods food(right?), so i try to collecting by hands. if my net is full size and collecting with machine boat, the capture amount of copepods may reach culturing amount of rotifers in my home. this trial of collecting is mainly for experiencing the knowlege of book. theoretically, catching copepods can be at night or daytime. what's the "tompang"? =join me? marinebetta, if my raising fishes should eat copepods and are valuable as Frank Baensch's, i will collect copepods three times a week like him . it is fine that my black oc. eat rotifers and bbs, recently, i have a batch 500+ of babies are 7 days old with one stripe.no copepod need for these. keithtanbb, thank you for your suggestion in culturing copepod. i try to culture them.

SRC Member Maxstar81 Posted December 29, 2005 SRC Member Share Posted December 29, 2005 Bro Dazza, Wanna make a trip out to Pasir Ris Beach to try? Can it it a beach combing & harvesting outing.

FuEl Posted December 30, 2005 Share Posted December 30, 2005 Nah I don't culture copepods. There are two types of copepods. The main group that is useful for fish larvae are calanoid copepods as these are pelagic copepods that swim around all the time. To culture these in sufficient amounts you will need very large culture volumes. Unfortunately, the copepods seen in aquaria are mainly the benthic type. These do not swim in the water column and fish larvae don't really have access to them. While it is rather easy to culture benthic copepods (since all they need is surface area), the low ingestion rates of such copepods by fish larvae don't seem to make such cultures worth the effort.

FuEl Posted January 1, 2006 Share Posted January 1, 2006 Hmm..no probs..but with that said culturing benthic copepods can be useful for other purposes. Such as feeding pipefish, mandarins and other small fish that are hard to wean onto dead food items. A shallow tank of bioballs should work well, with lighting or sunlight provided and with regular addition of silicates (good if your tapwater contains silicates). Increasing evaporation and replacing the lost water with silicate laden tapwater will see your diatoms bloom. That's natural food source for those benthic copepods.

SRC Member ciaolong Posted January 2, 2006 SRC Member Share Posted January 2, 2006 i found it super easy to culture pods my seahorse tank in my room since i havnt added the seahorses has become a pod farm it had almost 1 month without a pump on and the pods are crazy like nuts the tank only get natural sun light and there a bit of nurients in there so aglae is quite a bit (on glass) basicly its a 1ft tank with 1 piece of liverock from my propgation tanks which had the starting pods and i gave it a week and there were mass pods no equipment needed Quote Link to comment Share on other sites More sharing options...
SRC Member iantoh Posted January 2, 2006 SRC Member Share Posted January 2, 2006 hi there everyone, i heard a while back that some guys in sg are culturing calanoid copepods for commercial sales- anyone hear any updates about that? would love to get more copepods. off topic, but bro fuel, you know the suction syringe gun that researchers use to catch fish whilst diving? do you happen to know where i might be able to buy one? those look nice, and im thinking it might prove alot less stressful and troublesome if we could use those to catch fishes in our tank. cheers all, ian Quote My Goniopora Nano!

FuEl Posted January 4, 2006 Share Posted January 4, 2006 Wow guys culturing calanoid copepods? Probably linked to a hatchery? Anyway, never heard of those suction syringe guns before. Unless you are talking about those employed for submersibles.
