hey guys. i've been meaning to take a trip to Broward and check out the dipnetting action.
finally managed to go today, was only there for about one hour, but in that hour caught a lot and got a lot of information to share.

species collected or seen:
- bluefin killifish
- gambusia (normal and melanistic)
- sailfin molly (normal and melanistic - YES YOU READ RIGHT - PICTURE BELOW)
- least killifish/livebearer
- jewel cichlid
- mayan cichlid
- salvini
- ghost shrimp
- crayfish
- ramshorn snails, trapdoor snails, trumpet snails
- tadpoles!
- sunfish (possibly bluegill - pictures below)
- unidentified bass-like juveniles (pictures below)

what I didn't see that I expected to see from my previous trips to this spot:
- jaguars
- black acaras
- spotted tilapia
- tadpole madtoms
- fat sleeper gobies

noteworthy information:
- vegetation is growing well and densely. there are a variety of plants (notably cambomba-like and hornwort-like plants), but the one type dominating the area is the valisneria americana
- the gambusia, least livebearers and bluefin killifish that were caught were for the most part all unusually large and plump
- whereas I usually catch 1-2 crayfish, this time caught more than 20, ranging from new hatchlings to a 4-5" specimen with one inch claws.
- in this spot i usually catch jaguars and black acaras, at least 3-5 each trip. today didn't even see one of either species. likewise for tilapia.
- netted two mayans (3" and 5") but saw at least 3 10"+ specimens
- at least 3 big catfish are under the tunnel
- there are much bigger fish in that area than the 10" mayans, as more than once something BIG splashed...i'm thinking maybe huge oscars or something along those lines.
- caught several, and i mean at least 10-12 specimens of an unidentified species of fish (for me anyways), looking like juvenile bass but i can't tell which kind, if they are bass.
- saw melanistic gambusia, but actually collected a mostly black melanistic MALE sailfin molly (picture below). in the year that I've been dipnetting with the club i've never heard of a melanistic molly? is this a rare event?


now on to the pictures:

and last but not least...male sailfin molly (melanistic!!!) - this guy came home with us too :)

on a less pleasant note, when i crossed to the other side where I go under the bridge, we noticed there were a lot of fishing lines that looked to be stuck and had just been left there. at one point Mary noticed there was a big fish basically in front of us in the plants, it looked to be stuck or caught on something, so i get it out with my dipnet and what do you know, it's got a hook going through its mouth, attached to one of those lines that looked to be abandoned. the fish was very much alive but had some injuries, maybe from trying to break free of the hook or from being nipped at by other fish.

the line had been tied to an iron bar and left (most likely with bait) in the water. i cut the line at both ends, removed the hook from the sunfish and released it.
then I thought I should try to cut the other two lines that were "stuck" so no other fish would get hooked, and much to my surprise when I pulled on the lines both had sunfish hooked! :evil:

same procedure, cut the lines and unhooked both fish and released:

all three were between 6-8 inches and just gorgeous, specially the last one, which despite having been hooked by the biggest hook was the easiest to free and the one with least injuries:

i dont know who thought this was a good idea, but I find it cruel and dangerous, and i wouldn't be surprised if it is illegal. i took more pictures than what i'm posting here, of each step and each fish before and after, kept the lines and the hooks, and will report this to the FWC, as I want this moron caught :evil:

anyways, i had a fun time in that one hour I was there. and I feel like I did something good by releasing those fish and removing those lines, so all in all it wasn't a bad use of a morning :)

i know it's a lot of information to digest and a lot of pictures to load, but if you make it this far, please comment! I need help identifying the bass-like fish, want more info on the occurrence of melanistic sailfin mollies, and on the legality of leaving fishing lines hooked and baited in the water like that.

i hope you enjoyed the read and the pictures :)
 
some nice fish pics and great news that you found and released them fish, well done :good: .
 
Great pictures, and great catches! Where in the US is Broward (I assume it is US...)
sorry, sometimes I assume everyone lives in Miami! Broward is the next county north of Miami-Dade, where I live. it was about a 30-minute drive from my place to the spot. so Broward is just north of Miami, in South Florida, yes, the US of A :S

:good:
 
nice catches, i caught Pongo (yes i name my fish) 3 days ago in the lake behind my house

it was ided as a Phalloceros caudimaculatus well at least with that pic and this forum.
 
sorry to disappoint whoever identified that fish, but if you live anywhere in the united states, that fish is a male melanistic gambusia sp. (most likely affinis if you're in the east, holbrooki if you're in the west). common name for the fish is mosquito fish, and it is a native species to the US.
it is a very prolific livebearing species, and if you put a female with him you will get live fry within the month :good:

for a picture of the standard form female of the species look at my picture at the top of this thread titled "gambusia"
 
yeah im in Tampa, so i gues my question now, are gambusia agreesive? would it be safe to put my 3 males guppys with this guy?
 
i haven't kept them (they are usually treated as feeders) but the few times i've put them in my girl's tank they've seemed nippy. i would be worried for the guppies' tails.
anyways, if you have any more questions pm me, this thread is already too long to also sidetrack it! :lol:
 
Those unidentified bass look to be Largemouth Bass (Micropterus salmoides) Also, those fish that you released were most likely bait for turtles. It's legal to set those lines as long as you have a fishing license.
 
and leave them unattended like that? besides, those were pretty big fish, what size or kind of turtle would they need a 6-8" fish for with a tiny hook? :huh:

according to the Florida Fishing Regulations it is legal but the owner must tag the lines with date and time and owner information. these things werent tagged at all. either way, the fish are now (hopefully) living happily :shifty:
 
LOL,
You still catching those amazing Bluefins.
 
difficult to tell in the photos, but if the dorsal fin of the bass sp. in question is deeply notched (almost apearing as two separate dorsal fins) it is a largemouth. if one continual more rounded looking dorsal its a small mouth. also counting the last dorsal rays (without membranes inbetween) gives good clues as well. any more than 3 and its a largemouth. they are difficult to ID when tiny like that. another good clue is how far the jawline extends relative to their eye. largemouth "lips" extend beyond the eye whereas smallmouth only extend as far as the middle of the eye. but again, being only small specimins, can me difficult to tell. since you handled them and no doubt examined-up to you to determine sp.
as for the unattended lines. in NY "night lines" (or unattended hooks) are illegal even with a license. even live bait trapping (generally) requires special permits. i am an AVID fisherman(woman) and would never leave hooks unattended. for so many reasons. glad you did what you had to do. id have done the same :)

looks like a LOT of fun! i used to get paid to do similar things using seines on the Hudson River for fish population/id studies in the tidal marshes. good times there :good:
cheers

I wasn't trying to defend whoever put them there, just giving a possible reason for :)
