1.000 is pure freshwater, I thought. But a large number of people want to know which live plants they can use in their Supershrimp … But they are *all* wrong. The SG is just below 1.0 right now, so I still have a few weeks to go for the full BW effect. Sorry, your blog cannot share posts by email. The BW species will live indefinitely in BW, the FW ones for some weeks to months. Post was not sent - check your email addresses! What people have been doing for decades is throw some plants in brackish water and observe how some die immediately but others stay green for a long time. I tried to take a picture of one but it doesn't even show up in the tank! So what’s going on? 20 Gallon, 20 Gallon Long, 10 Gallon, and 2.5 Gallon with gravel for most of them and filters and whatnot for sale... Ghost shrimp come as both FW and BW species, which are extremely difficult to tell apart. Although the culture of Macrobrachium has received some attention in a few countries of the region, the Task Force does not consider it necessary for the Centre to undertake any investigation on Macrobrachium culture for the present. There is, therefore, some urgency in establishing viable hatcheries for local species. All Rights Reserved. Species tank or … 2. They proudly come to the forum to announce after a week, a month, or several months that their plants are still doing great (but the problems start later for the second group and most of the time they don’t come back to report on the problems). Their shrimp start dying shortly after, or they start developing an algae or bacterial bloom. Here’s what’s really happening: Even at very low salinities those plants are dying or dead…even though they are still green. How can it be below 1.000???? A true brackish water denizen is the red-nose shrimp Caridina gracilirostris. It's only co-inhabitant would be malaysian trumpet snails, and maybe some pond snails. Another high-priority item of research will be the formulation and production of suitable compounded feed for juvenile and adult shrimps in ponds. Several species of penaeid shrimps contribute to commercial fisheries in Latin America and a screening of species is necessary to determine the more important species to be investigated by the Centre. The production of larval food, which is of considerable importance in the rearing of shrimp larvae, may probably not present major difficulties as there are a number of known sources of Artemia in the region which are not utilized at present. AquariaCentral.com, a division of Monster Aquaria Network, LLC. #1 I'm looking for a good brackish shrimp species to inhabit my refugium. Of course not. How about “Marimo Balls”? Experimental work on shrimp culture has been carried out in Honduras, Brazil, Colombia and Argentina, and pilot farms are now in operation in Costa Rica and Panama, both on the Pacific Coast. Or a BW shrimp that is being sold as food and they just don't care? The only plants, so far, that thrive and reproduce in Supershrimp tanks are the Supershrimp macroalgae, which is an unknown species of Chaetomorpha adapted to very low salinity (not the Chaetomorpha for reef tanks sold in stores and online) and the very mysterious (it simply appeared one day in one of our Supershrimp tanks) Supershrimp mossball (which is NOT a marimo ball, more on that in another article). Juveniles are collected from mangrove swamps for stocking the ponds. So the first thing they do is to go on the internet and search for “brackish tolerant plants” or “brackish water plants”. Some people use rocks, others use plastic plants to decorate. Hence, it’s unlikely that the marimo balls commonly sold in stores and online are adapted to brackish water at the salinities at which we keep our Supershrimp. Grass shrimp have transparent bodies but they also have pigment granules that they can use for camouflage. So they go out and buy these plants and throw them in their brand new Supershrimp tanks. In the shrimp culture project sponsored by the Banco de Desenvolvimento do Rio Grande no Norte in Natal (Brazil), considerable advances are reported to have been made in the hatchery production of shrimp (Penaeus brasiliensis) larvae, using the techniques adopted in the Galveston Laboratory of the United States National Marine Fisheries Service. The possibility of combining pond fertilization and supplementary feeding to obtain satisfactory production needs to be investigated through appropriately designed yield trials. Marimo balls are a species of filamentous algae (Aegagropila linnaei) with a worldwide distribution. A major problem faced in the culture of shrimps is the production of larvae or juveniles. Of course not…. Also, even if the shrimp did hatch, your chances of raising the young are slim to none. Even in marine tanks the plants stay green for a very long time. Didn’t literally dozens of websites list these plants as perfectly fine in brackish water? I guess I've got a lucky batch then. It not only occurs in ball shape but more commonly attached as a carpet-like flat growth to rocks, or as free floating filaments in the water and on the substrate of mostly freshwater lakes. Even in Ecuador, where wild juveniles are collected from the mangrove swamps for culture, one of the difficulties in the expansion of the industry is the insufficiency of seed. And the reverse, of course. It wouldn't surprise me if they could handle brackish water full-time. When I collect Sailfin Mollies in brackish water, I'll catch ghost shrimp and other shrimp varities right along with them. You must log in or register to reply here. Well, ordinary ghost shrimp live well in brackish water anyways. To add to that, commercial fishermen claim that their catches are adversely affected by the large-scale collection of juveniles by shrimp culturists. So far, they seem to be doing a crack-up job of cleaning and are very active! A suitable shrimp hatchery and a series of brackishwater ponds should be built in the Cananeia Sub-Centre in the course of the next two years to enable further investigations on shrimp culture. Some people use rocks, others use plastic plants to decorate. “The brackish water salinity is between sea water and fresh water,” says M Jayanthi, joint secretary at CIBA. There is widespread interest in the culture of shrimps and prawns in many countries of Latin America. It wouldn't surprise me if they could handle brackish water full-time. Cheers, NEale. Beware Of So Called “Brackish Water Plants” Supershrimp tanks are great, almost no maintenance, decorative habitats for our beloved shrimp. for larval and post-larval stages; (vi) formulation and preparation of shrimp feeds using locally available ingredients. Immediately they are bombarded with search results that seemingly indicate that there are lots of plants that can survive and thrive in brackish water. Yes, they did. will be applied in shrimp culture investigations as well. So, theoretically at least some populations (at least the flat growing, rock-attached ones) of this species should be adapted to brackish water, even though the ball shaped populations exclusively occur in freshwater lakes. Juveniles are collected … JavaScript is disabled. Upon observing that these plants stay green, the satisfied freshwater aquarist declares that the plant “does well” or is “brackish water tolerant” and spreads the info online or confirms one of the articles already spreading the misinformation. Behind the Cherry Shrimp, it is the most popular freshwater Shrimp in the hobby Interestingly, because they are incredibly hard to breed, the majority available to buy are actually wild Shrimp. The refugium is in a 30G tank, with ~20G of liveable space (the rest occupied by a DIY crushed coral filter and on the other side the return pump section). 1. But forget about them providing any meaningful supplement to the diet of your fish: these predators will eat them all long before they get a chance to breed. It’s something that is still being perpetuated by well-meaning but ultimately ill-informed *freshwater* aquarium keepers who have dabbled a bit in low salinity brackish water (usually up to around 1.004SG or 5ppt). Hum...then I will watch those guys closely. They are only 1/2 inch to an inch long. For a better experience, please enable JavaScript in your browser before proceeding. For that matter, several types of food shrimp are being raised in freshwater despite the fact that they were originally fully saltwater shrimp. It is similar to the Amano shrimp in shape and colour except that it … Commercial farming, however, has been confined to a single commodity, shrimp – largely Penaeus monodon (the native giant tiger prawn), and Penaeus vannamei (the exotic whiteleg shrimp) – due to its high export potential. Some of the engineering studies proposed to be carried out in connexion with the culture of Mugil spp. But a large number of people want to know which live plants they can use in their Supershrimp tanks. Have any of these people maintained a brackish water tank with a thriving and multiplying population of these plants? Many of our forum members have tried growing Marimo balls in their tanks. Specifically they find that java moss and java fern “do well” in brackish water. Supershrimp tanks are great, almost no maintenance, decorative habitats for our beloved shrimp. Some, like java moss, even grow a little at first at very low brackish conditions (1.004SG) before eventually dying. Are you reading it correctly and did you calibrate the refractometer??? Is that so??? Since we can't have the normal catfish or clean-up crews that we can have in a FW tank...what would you suggest for a BW tank? Local species of shrimps, mainly Penaeus vannamei and P. stylorostris are cultured in earthen ponds built in mangrove areas following the traditional techniques adopted in Southeast Asia (Cobo, 1977), yielding 500-600 kg/ha in nine months. The myth that plants like java moss and java fern grow and thrive in brackish water is decades old. When I collect Sailfin Mollies in brackish water, I'll catch ghost shrimp and other shrimp varities right along with them. Even though their marimo balls (mostly) don’t seem to die immediately and stick around for months or even a year+, they never appear to grow or multiply.
