    Since Thursday, corpses of dead tilapias have littered the shores of Lake Toho, 90 km northwest of Cotonou. Nobody knows yet what is behind this hecatomb. The Mono is a region where one lives mainly fishing, the activity suffers therefore.

    When we approach the shore of Lake Toho, it smells like rotten fish, there are plenty of flies. Between Thursday and Saturday, thousands of fish were mysteriously crushed. Tuesday, silverfish corpses still littered the ground, they will be buried on Wednesday.

    Most of the tilapias that will be cremated belong to Olivier Zaga, a fish farmer. His 40,000 fry had matured, he was just starting to sell them when the tragedy happened, he lost everything: "We lost all our fish, 40,000 fry. We are completely at zero. Are we going to leave? If we have the means, we will do it. "

    If nobody explains the cause of this unprecedented hecatomb, just before, a creamy pink substance appeared on the water. Samples are being analyzed and pending the results, the government has taken action. "We asked that the water bench be no longer sailed and that the sinners, those we have there, leave the water at rest for at least two weeks, even if the danger can pass," details for RFI the Minister in charge of Fishing, Gaston Dossouhoui.

    The whole lake is not soiled, explains the minister. The fluvial brigade and the experts sailed for several hours and fished live alvins.

    In Benin, the mysterious death of Toho Lake fish

    How are tens of thousands of fish dead? It will be to the many experts solicited to solve this enigma.

    By RFI Published on 30-05-2018 Modified the 30-05-2018 at 04:22

    On May 21, tens of thousands of fish died in Toho Lake, about 100 kilometers northwest of Cotonou. A hecatomb. To understand what has happened, the government has committed the central laboratory of health safety control for the analyzes. He published his results Tuesday, May 29 in Cotonou.

    The laboratory is formal: the waters of the lake have not been contaminated by an external product. This is the essential conclusion, explanation of the director of the laboratory, Kisito Chabi Sika.

    "There was no contamination of Toho Lake by external input. This phenomenon is certainly endogenous to the lake and these are hypotheses that remain to be verified. The lake, we put it from this moment under surveillance to see in the coming days how the phenomenon will evolve. "

    What has been collected and analyzed are sediment, lake water and the flesh of dead fish. In the absence of toxic products and given the magnitude of the disaster, the laboratory explores another track. He suspects intoxication of endogenous origin to the lake, arrived by underground infiltration.

    Further analysis is needed to confirm, and for that, it is necessary to broaden the skills and associate divers, geologists and call upon international specialized laboratories. The work is not finished. As for the prohibition to fish, sell and eat fish, it is still in force ...

    At the same time, Kpinnou city watered by Lake Toho, a fishing town and good fish, lives in slow motion.

      Benin - Lake Toho Drama: Professor Michel Boko and Patrice Sagbo question the results of the laboratory

      Rufin Patinvoh June 4, 2018
      ...
      Patrice Sagbo suspects these pesticides to be at the base of the fish drama. According to him, it is common ground that people practice pesticide farming around the lake. It can be assumed that the lake was polluted by pesticides and that the fish died from heat because they no longer had oxygen. He therefore does not believe in the results of the analyzes that rule out the possibility of pollution of the lake by pesticides.

      Controversy over Toho Lake results: Kisito Chabi Sika explains

      Press Group Le MATINAL June 4, 2018

      Guest on the program "Tour de contrôle" of Golfe Television Saturday, June 02, 2018, Kisito Chabi Sika, Director General of the central laboratory for food safety (Lcssa) has spread the capabilities of its structure. He also reassured the public about the doubts expressed about the provisional results of his laboratory following the analyzes carried out on Lake Toho intoxication.

      "Initial analyzes by the Central Laboratory for Food Safety Control (LSCA) failed to elucidate the causes of this likely intoxication of fish in Toho Lake." This was stated by Kinnou Kisito Chabi Sika, Lcssa's General Manager on the "Tour de Contrôle" show on Saturday, June 02, 2018. According to his explanations, more than thirty molecules of pesticides belonging to four major families (organophosphorus, organochlorine, carbamate, pyrethroid) and five (05) families of veterinary drugs (Beta-lactam, amphenicols, Macrolides, Tetracyclines, Sulfamides) were sought through advanced technologies. "To date, we could just remember that the lake water, which is the predominant contact environment for fish, does not contain traces of the pesticides of the families mentioned in terms of the detection limits (Ld) of the methods of analysis that allowed the technical research operations to be carried out, "he said. He therefore reiterated that the mass death of fish can not be explained by the presence of any toxin belonging to pesticides and veterinary drugs sought. Pending the continuation of the additional toxicological investigations with the foreign laboratories of the sub-region, the Director of Lcssa added that a depletion of the lake in dissolved oxygen is not to be excluded. Because, several hypotheses are still emitted to widen the searches. There is, for example, a poisoning of the fish either by overloading organic matter by decomposition of the aquatic flora, or by the phenomenon of the rise of ferric ions through the rejects of junk, underlined the guest.
