Talk:Marine shrimp farming

message: It has been pointed out at the FAC discussion that the "positive sides" of shrimp farming were not mentioned. I plan to add a new "Social impacts" section, but from what I've found so far, it won't be exactly "positive", either. Are there any positive facts about shrimp farming? In third-world countries, they seem to generate profit only for a small minority, while causing losses for the general population. The old issue of external costs...
Here are my links so far, feel free to add more, especially if you do find positive mentions! (The list is completely unsorted and unpruned, and I haven't really reviewed any of the articles pointed to yet. Just the results from some Googling and a quick glance to check whether or not it might be relevant.)

*McClennan, C.: White Spot Syndrome Virus – The Economic, Environmental and Technical Implications of the Development of Latin American Shrimp Farming, Master's Thesis, Tufts University, 2004.
*:Reviews the development of shrimp farming in three Latin American countries: Ecuador, Peru, and Mexico. Places an emphasis on economic developments, with a focus of the effects the Whitespot outbreaks of the late 1990s had. Also highlights some of the differences between Ecuador (an early adopter, tropical country, weak government control, shrimp farming controlled by large companies) and Mexico (late adopter, sub-tropical environment, strongly regulated business, shrimp farms mostly owned by locals or local co-ops). The basic thesis is that disease problems led to a growing recognition amongst shrimp farmers that their current practices were indeed self-destructive, and that they for economic reasons alone realised that they had to develop more sustainable ways of farming. Also mentions the financial problems caused by diseases (wipe-out → no income → cannot pay back loan rates → debt rises → farm folds). The boom period—high profits were possible in the 1980s and early 90s, but apparently only because the negative external costs (i.e., the environmental impacts) were ignored—is over. WSSV led to generally more government regulation of shrimp farming and mangrove protection laws, although enforcement is a problem. The discussion of Peru, a minor producer nation, is rather short. The paper has some nice overviews of the most important viral diseases (the same as in the article), with graphics showing their spreading. Lupo 07:01, August 17, 2005 (UTC)

thread_title:  Social impacts 

message: Lupo, here are a couple links to NPR (National Public Radio) stories relating to shrimp farming:
*"In Vietnam, Shrimp Farming a Glimmer of Hope" (Weekend Edition, May 1, 2005)
*"U.S. Shrimpers Seek Protection from Imports" (Morning Edition, January 1, 2004)
*"Shrimp Farming" (All Things Considered, February 14, 2001)
These are all audio files so if you have trouble listening to them let me know and I'll try to find transcripts.  I'll also look for more links - this is just one source I remember hearing.
* give some idea of profits for peasant farmers in Thailand.
*World Bank documents] on shrimp farming projects - includes this pdf file with a summary of 35 case studies.
*THIS PAGE (by World Bank, WWF, and FAO) is great.

:Indeed I cannot listen to your audio links—I have never found out why, but for some reason I have no sound on this crappy computer. Sorry. NPR transcripts appear to be pay-per-view. Anyway, I prefer written publications. TV and radio broadcasts are so ephemeral, and it's basically just another person stating something. One would need to assess the veracity of any such information in each case, and the danger of arguments along the lines "this or that station is too liberal/too conservative/left-wing/or whatever" is just too big for my taste. (Note that I don't know NPR at all; this is not some disguised criticism of that particular station.) That's why I prefer peer-reviewed scientific publications (they generally tend to be written more carefully), or summary reports like those from the World Bank you pointed out, where one may also safely assume that they are reasonably fair. In some cases, I also settle for publications from other sources (renowned newspapers, Nature, or even web sites of others (such as Rosenberry's)), but only if the facts stated there are corroborated by third parties. For undisputed facts I'm ready to use any odd web site that explains it best. Lupo 09:27, August 17, 2005 (UTC)

message: The lead para uses "shrimp" and "prawn" without the 's' for plural, but most of the rest uses 'shrimps'. Also, "growout" is either BritEng (or CwE), or else is a technical term...is 'rearing' or 'raising' pond only AmerEng, or would one of those work as a compromise? 198.104.63.140 02:21, 12 October 2005 (UTC)
replies: text: I'll check about "shrimps". As to "growout": this seems to be a technical term, it is used in many publications on shrimp farming. Lupo 15:48, 25 October 2005 (UTC)
replies: text: The plural of "shrimp" can be either "shrimp" or "shrimps", both are correct. I wonder if there is a distinction like "fish" vs. "fishes", i.e. using one for a collection of individuals and the other when referring to multiple species of shrimp... Lupo 07:56, 26 October 2005 (UTC)

replies: text: It's a three-page empathic personal account of a Filipino marine scientist who has been working on the topics of mangroves and aquafarming, in particular shrimp farming, in the Philippines since the 1970s. It gives a brief summary of the issues and generally agrees with our article. I have not found any new angles. She confirms the points made here: social disruption (in the Philippines, most shrimp farms are owned by a few wealthy, influential families, not local owners), ecological problems, law enforcement problems, etc. The silvofisheries mentioned by her are also mentioned in the World Bank/NACA/FAO/WWF report; these are still very much in the research stage and are an attempt to develop low-impact, small-scale aquacultures within mangrove areas without clearing the mangroves. Whether that approach is ever amenable to large-scale, export-oriented shrimp farming is uncertain at best. The essay is also available at the Science Magazine Global Voices series (probably will be moved to  in November 2005), together with a nice little slide show. Since the essay is not a peer-reviewed publication and does not contain any references itself, I feel it is not suitable as a reference for our encyclopedia article, but it might be worth adding to the "External links" section once the URL at Science Magazine has stabilized.

replies: text: The terminology is not strict. See Footnote 1. The photo shows a nauplius of Fenneropenaeus chinensis, commonly called "Fleshy prawn", "Chinese white shrimp", or "Oriental shrimp". See Penaeus. Lupo 07:34, 13 February 2007 (UTC)

Edited Document:
While extensive farms mainly rely on the natural productivity of the ponds, more intensively managed farms rely on artificial shrimp feeds, either exclusively or as a supplement to the organisms that naturally occur in a pond. A food chain is established in the ponds, based on the growth of phytoplankton. "Fertilizers" and mineral conditioners are used to boost the growth of the phytoplankton to accelerate the growth of the shrimps. Waste from the artificial food pellets and excrements of the shrimps can lead to the eutrophication of the ponds.
Artificial feeds come in the form of specially formulated, granulated pellets that disintegrate quickly. Up to 70% of such pellets are wasted, as they decay before the shrimps have eaten them. "The shrimps are fed two to four times daily;" the feeding can be done manually either from ashore or from boats, or using mechanized feeders distributed all over a pond. The "feed conversion rate", i.e. the amount of food needed to produce a unit (e.g. one kilogram) of shrimp, is claimed by the industry to be around "1.2–2" in modern farms, but this is an optimum value that is not always attained in practice. For a farm to be profitable, a feed conversion rate below 2.5 is necessary; in older farms or under suboptimal pond conditions, the ratio may easily rise to 4:1.
Additional Information:
#1. The usage of too much fertilizers could result stunted growth of prawn. (Not recommended, unless in serious condition)
#2. Good Pellet Feed retain its shape and would only disintegrate in about 2.5 Hours.
    Pellets lost all its fragrance and nutrients after 3.5 /4 Hours.
#3. FCR - Feed Conversion Rate = ???? Kg of Feed : 1 Kg/lbs of Prawn. (Fixed). FCR= 1.4 - 2.0. 
#4. <FCR = higher Profit Yields. >FCR = Lower Profit Yields.
#5. The Shrimps are fed 2 to 5 times daily.
    a. 6AM, 11AM, 2PM, 5PM, 8AM, 11PM/12AM (This is usually its routine schedule)
#6. There are certain practices on Feeding the Shrimp:
    a. Distribute more feeds on the deepest part of the pond.
    b. Distribute more feeds on the sides, compared to its center. (That's usually where the waste from artificial feed
       and excrements of the shrimps are).
    c. Powder formed of feed usually mixed with the ponds water for easy distributions.

message: I found this article very interesting, having read it right after today's featured article on krill. The subsection "Life cycle of shrimp" calls the third larval stage "mysis" (or myses in its plural form), yet mysis redirects to the article on Mysidacea, not a developmental stage, but rather a different group of species than the Penaeidae described in this article here. The article on krill mentions the larval stages "nauplius, pseudometanauplius, metanauplius, calyptopsis, and furcilia". The article on nauplius lists zoea, mysis, metanauplius, calyptopsis, and furcilia as "other developmental stages of crustaceans". It's possible that this is all correct (except for the misleading redirect, probably), but it's confusing to an uneducated reader such as myself. Unfortunately, I found no article on crustacean life cycles. Anyone know how to untangle it? ---Sluzzelin talk 07:53, 8 December 2007 (UTC)
replies: text: Indeed, that's confusing. Solved by changing the two links to go to Mysis (larval stage) instead. We don't have an article on it, yet. Lupo 10:26, 25 April 2008 (UTC)

message: In the opening paragraph, it says Brazil is the largest producer from Latin America. Under the section "Economy", the chart clearly shows Ecuador as consistently producing more every year. Perhaps that line should be edited, or removed completely? Either the chart or the sentence is wrong.  — Preceding unsigned comment added by Z06 (talk • contribs) 15:39, 24 April 2011 (UTC)
replies: text: Indeed; thanks for pointing it out. In 2005, the latest statistics available were those of 2003, and in that year, the Brazilian production was indeed much higher than that of Ecuador, so the lead was arguably correct when it was written. But in the following years, Ecuadorian production apparently recovered, overtaking that of Brazil again. Lupo 17:15, 24 April 2011 (UTC)
