Relation between spawning and water temperature of Oplegnathus insignis in North of Chile

-

I published my study about spawning of Pacific beakfish at North of Chile. Full text at my archive.

Abstract
Since 2006, the project "Optimizacion de la tecnologia de procuccion de juveniles de San pedro (Oplegnathus insignis)" is running under INNOVA CORFO with CORDUNAP.
Wild captured O. insignis are rearing at Universidad Arturo Prat Ciencia Del Mar (UNAPDCM) since 2002. Ten females (biomass 13.07 Kg) spawned 1,768,292 eggs with 20 times spawning under water temperature 19.3+-0.58C from January 7 to March 17, 2007. Spawning egg consist 1,574,492 floating eggs (89.0 %) and 1,457,692 hatch-out larvae (92.6 %).
O. insignis is multiple spawning fish and the egg behave isolated epipelagie eggs, diameter is 0.87 to 0.96 mm. The egg has one oil droplet, diameter is 0.16 to 0.21 mm. Between spawning quantity and the average water temperature while 4 days before spawning shows the most strong relation at 19.6 C. Thus, the result suggests that the fish takes 4 days to mature and spawn and the spawning are abundant at water temperature range 19.6 C.

Tokyo fish wholesale market prices from 2008 to May 2012 Masatoshi FUTAGAWA / CORDUNAP July 13, 2012 Tokyo wholesale fish markets, Tsukiji (main market), Adachi and Ohta, are part of Metropolitan Central Wholesales Market in Tokyo which consist of 11 markets in Tokyo, is the largest fish market in the world. The market deal about fresh, live, frozen, dried, salted, fermented and processed products about fish, shellfish, shrimps, crabs, algae as the market dealt 527.5 thousand MT and 5,591.8 million USD with 470 items in 2011. I will report the price of some major fish in the market from 2008 to May 2012. Tunas Bluefin tuna (BFT) consist of similar two species, Pacific Bluefin tuna (PBFT; Thunnus orientalis ) distribute at Pacific ocean and Northern Bluefin tuna which grow bigger (NBFT; T. thynnus ) at Mediterranean sea and Atlantic ocean. Southern Bluefin tuna (SBT, T. maccoyii ) distributes the southern hemisphere, Yellowfin tuna (YFT, T. albacares ) at tropi

Overview of marine ranching in Chile

Reduction of coastal fish resources is common problem in the whole world due to overfishing. Qn the other hand, demand is rising due to health consciousness (less cholesterol), contamination of chicken (influenza), cow (BSE) and pork (HEV). Marine ranching is the one of solution to recovering coastal fish resources which has operated in Japan more than four decades. The result shows that some fishes are recovered, even increased, and contribute benefits. Chile coast water has higher productivity compare to Japan and the method produce more fishes quickly. It may create new business model which has less energy consumption, no contamination and sustainable production, and create employment at rural area. 1.             What is Marine ranching 1.1.              Idea and activities General ideas of marine ranching are releasing fish juvenile dismissing species into artificial reef (shelter) which design to protect from predators at reservation. The fish takes natural foods a
