What is happening in LIS Long Island Sound, in the water?? We are addressing part of this question...
==========================
FIVE FUNDAMENTAL sub-QUESTIONS:
- # 1) WHICH are the significant fish etc. ("etc" = & other marine life) in LIS and nearby waters?
- # 2) Which birds EAT which of these fish etc? Which fish are not prey to birds?
- # 3) WHEN are these fish etc. here in LIS and nearby waters? Many fish are migratory & cyclical.
- # 4) Which of these fish etc. have actually been reported in RECENT weeks? How seen? By who?
- # 5) WHO is knowledgeable about these fish matters, and will they collaborate with us?
==========================
From a bird watcher's point of view :
Why do seabirds (and whales) concentrate in some waters, and what are they eating there???
Since fish (and plankton, etc) are such essential food items in the diet of most seabirds, it is important that we understand them better, including their 1) seasonal changes and 2) long term trends. The changes in fish numbers, distributions and health have a large impact on the success and survival of many seabirds (and where seabirds tend to congregate). Seabirds often search for fish (and plankton) concentrations, and we should know which fish species they are eating.
MAIN QUESTION (related to #4 above): Can we find or produce a quarterly or monthly report on the currently changing fish patterns (fish species, ages, numbers, distributions) in nearby waters, such as LIS Long Island Sound, Montauk and Long Island South Shore, Stellwagen Bank, The Gulf of Maine, Georges Bank, Scotian Shelf, Grand Banks, etc?
To do this, somebody has to be able to answer this simple underlying question: Which fish species are ACTUALLY in the water now, right in front of us, as we stand on a ship?
How do we know which fish are "out-there" from month to month, and how they are changing, e.g., migrating? Who knows that? Who is "watching" these fish changes in-the-field, from month to month? Who are these "fish watchers"? How are they "watching"? What are all the methods being used to monitor fish populations, both formal/scientific and informal/nonstandardized?
And secondarily, can we note any relationships being observed with birds (such as flocks of terns, gulls, shearwaters, gannets, cormorants, loons, ospreys, alcids, etc.) feeding on these fish?
Because of our emphasis on "seabirds" we are mostly focusing on salt water fish, with more attention to pelagic species and less on ground fish. Which raises an incidental question about scientific fish surveys: are most of them trawl surveys, focusing more on ground fish than pelagic fish??
We will try to work through this main question at this post, starting with fishing reports, such as:
DEEP: Weekly Fishing Report <<for LIS and CT watershed in 2018.
fishreport092018.pdf <<for the most recent week. Note the good reports on Atlantic Bonito and Little Tunny.
and these more commercial fishing reports:
Weekly Fishing Reports for South Shore Mass. to Maine New England - The Fisherman Magazine
October 8, 2018 Fishing Report: Hillyers Tackle, Waterford CT - The Fisherman Magazine
We will include inputs from fish experts from many areas, including commercial fishing, recreational fishing, academic, governmental, tackle shops, museum collection curators, etc. This new project is already receiving useful information from many subject matter experts and project partners. These two groups include P.Auster, M.Bull, P.Comins, I.Devlin, K.Douton, J.DiCostanzo, K.Hartel, D.Hudson, A.Jordaan, L.Kaufman, B.Lucey, M.Male, K.O'Brien, M.Sedotti, D.Wessner, C.Witek, C.Wood, etc etc.
Tackle shops could be another key source of valuable information, e.g., J&B Tackle Co in Niantic, with outstanding store manager Capt. Kyle Douton.
EXAMPLES:
Here are two interesting samples from the CT DEEP Weekly Fishing Report on Sept.20th. Is this the best contemporaneous fish information we have for LIS, from week to week? These small tuna species were not reported in LIS earlier in the summer, so you can deduce the changing patterns of fish to some extent from studying these qualitative weekly fishing reports...
==========================
"ATLANTIC BONITO & LITTLE TUNNY. Just got back from a great morning of fishing today (Sept 20th). They are here feeding on the crab hatch and forage fish. They are fast movers and moving to different locations is important. However, the action in CT is heating up and many fish have moved into the western Sound. Big catches of these small tunas have been reported from Griswold Point. Pleasure Beach, Pine Island, Bluff Point, Groton Long Point to Norwalk/Darien. Shore anglers are scoring at Pleasure Beach, Ocean Beach, Seaside, Harkness Memorial and Rocky Neck State Park. These small tunas are also cruising around from Pt. Judith, Watch Hill to Bluff Point (including Fishers Island Sound), the Race to Little Gull Island, from Bartlett Reef to Black Point. Dawn and dusk is the best time to fish for these inshore tunas. They are also feeding heavily on young of the year transparent anchovy. Try casting metal (heavy) lures (Swedish pimple and Epoxy jigs) to feeding fish on the surface. A jig with a plastic swimming bait (sluggos, fin-s-fish, super flukes) and no weight on the leader has been very productive. A quiet approach and finding birds (gulls/terns) actively feeding is the key to a successful trip. Jigging for them also works when they are close to the bottom."
==========================
"BLUEFISH fishing has improved a little. They can be found in good numbers the eastern sound (find the birds). More recently good numbers of bluefish can be found in the lower estuaries, rivers and beaches feeding on menhaden/anchovies. The “Top-water” bite continues to be very good, look for the “blow-ups”. Bluefish fishing spots include the reefs off Watch Hill, the Race, Thames River, Sluiceway, Plum Gut, Pigeon Rip, lower Connecticut River, Long Sand Shoal, Sixmile Reef, Falkner Island area, New Haven Harbor and upper reaches, lower Housatonic River, buoys 18 and 20 off Stratford Point, Stratford Shoal/Middleground, Penfield Reef, and Cable and Anchor Reef. SNAPPER fishing has improved in the tidal creeks and rivers with fish measuring 6 to 10 inches in length."
==========================
Other "fish" mentioned by LIS fishermen in their August reports included:
Fluke, black sea bass, porgy(scup), mullets, bluefish (and snappers), menhaden/bunker, striped sea robin, northern kingfish, sand shark, humpback, blackfish (tautog), spearing, weakfish, eels, hickory shad, blue crab, Jimmies.
Of course mention of these fish species (Atlantic Bonito, Little Tunny, Bluefish, Menhaden, Anchovies -- all of various age classes and sizes) makes us wonder which bird species may eat them, and how important they may be to those birds. We will focus on this.
RELATED QUESTIONS:
From a birding and ornithological point of view we cant fully understand the birds and seabirds of a particular body of water such as GOM (Gulf of Maine) or LIS (Long Island Sound) unless we also understand the fish and other lifeforms on which they depend for food and survival. This leads to a series of questions we need to address:
1) What are the predominant 20 or 50 fish species in, for example, the LIS? Both pelagic and ground fish.
2) Are the numbers of these species trending in any long term directions?
3) How do the numbers of these species change seasonally through a typical year? What are the explanations? A great example for this, for California waters, is this site: Seasons in the Sea - Home Page
4) What about this particular year? How have these numbers been changing the last month, or week? Which species have been seen very recently, where, by who, identified how (in hand, photographically at a distance, etc)? And have there been any noteworthy events, such as schools of one species blitzing schools of another fish species?
========================
Basically this is a citizen-science initiative, hoping to get more amateur naturalists and bird watchers to focus on fish and how they are changing (and of course, for us to tap into the knowledge which fishermen and fish scientists already have). We are currently assessing how much we know in this area, and how we can learn more (perhaps by bird watchers starting to catch&release fish, and photograph fish, from above and from below the water). We need to document, for example, the basics of fish in LIS, what we know and dont know, and then go forward from there. We will try to learn this from every source possible, including fish experts and doing our own first-hand field research, with fishing rods, nets, cameras, etc.
========================
SOURCES OF FISH INFO: List of all current methods of monitoring fish in LIS and nearby waters:
- Fishermen catching fish.
- DEEP dock surveys, interviewing fishermen.
- Fishermen reporting some of the fish to tackle shops.
- Tackle shops and charters reporting to The Fisherman Magazine.
- DEEP weekly LIS fish report, in warmer months, with data from fishermen (via charters and tackle shops).
- CT DEEP LIS estuarine seine survey, at several inshore areas.
- CT DEEP LIS Trawl Surveys "LISTS", since 1984.

- What else??
=========================
WHAT FISH ARE ACTUALLY IN THE WATER RIGHT NOW, right in front of us ??
Do some of our own sampling, first-hand (catch & release), with hook, net, camera, fish-finders, etc. Here is our first sampling with underwater photography, in this case, about ten miles NE of Cape Ann, MA: will video camera just under ocean surface show anything? - YouTube
And also contact all the sources above, to learn what they know.
=======================
PLAN:
Focus on LIS Long Island Sound (and GOM) initially.
- Get to know and network with core fish experts, including fishermen, scientists, etc.
- Assess what is known and not known.
- Try to work with experts to fill in a few gaps, to document what is known but not published.
- Start with a TopTen approach, for fish, plankton, seabirds, etc.
- Draft a web page for each of the TopTen fish in LIS, including what categories they fit into, what they eat, what preys on them, their life cycle, their seasonal cycle, etc.
========================
CATEGORIZING FISH: is this a useful way to categorize fish?
1. "Vertical":
- Pelagic (the rest of the water column).
- Demersal (just above the benthos/seabed).
- Benthic (the seabed and its ground fish).
2. "Horizontal":
- Freshwater.
- Anadromous (born in fresh water, e.g., salmon, striped bass).
- Catadromous (born in salt water, e.g., eels).
- Estuarine (e.g., LIS).
- Marine/Oceanic.
3. Size and Trophic levels:
- Apex Predators: Sharks and billfish.
- Gamefish and other medium sized fish.
- Bait/forage fish, including juveniles of larger fish.
- Fish larvae and fish eggs.
========================
FISH CALENDAR FOR LIS:
Is there a Fish Calendar for LIS? Can we assemble one, based on collective expert knowledge? We could start with the Top 25 fish species, and then gradually expand to the Top100 species. Here is the only/best Fish Calendar I could find for LIS, from the PonusYachtClub in Stamford CT...
Here is the new 2018 Forage Fish Calendar for LIS, from CT DEEP (David Molnar and Justin Davis):
Here is my draft LIS Fish Calendar (Fish Calendar for LIS 2018 MIXED - Google Sheets), derived from the 2018 Fish Calendars from CT DEEP, especially from David Molnar and Justin Davis. Click to enlarge this image, and then press ESC key to return...
We could start with these top 25 fish species, as listed in the offshore "deep water" LIS food web model by R.Zajac in 2008 (C:\RZ\LIS Food Webs\LIS FOOD WEBS FINAL REPORT\Zajac et al 2008 Food Webs in LIS Final Report EPA LISS.wpd -- we believe this is the only known formalized food web model for LIS!):
